internal/auth/oidc:
floor: 90
why: |
Bundle 2 Phase 3 — OIDC service coverage gate. Phase 3 spec
pins the floor at 90 explicitly because every fail-closed
branch is load-bearing for the security posture: alg pinning
(deny-list HS*/none + allow-list RS*/ES*/EdDSA), audience
re-check, azp enforcement on multi-aud tokens, at_hash
REQUIRED-when-access-token-present (Phase 3 lifts the OIDC
core "MAY" to a service-level "MUST"), iat-window window,
nonce constant-time-compare, single-use state replay defense,
PKCE-S256 mandatory, IdP downgrade-attack defense at
provider-load + RefreshKeys time, JWKS-fail-closed semantics,
group-claim resolution + userinfo-fallback fail-closed
semantics, token-leak hygiene. A regression in any one of
these branches is a security incident; the floor catches it
before the commit lands. The mock-IdP fixture in
service_test.go is the load-bearing harness.
internal/auth/oidc/groupclaim:
floor: 95
why: |
Bundle 2 Phase 3 — group-claim resolver. Hand-rolled (no
JSON-path dep per Decision 10); ~150 LOC, every branch
exercised by 19 unit tests covering the documented IdP shapes
(Okta string array, Keycloak realm_access.roles, Auth0
namespaced URL claim, single-string normalization,
deeply-nested 3-segment walks) plus every fail-closed branch
(empty path, missing key, missing nested key, non-object
intermediate, bool/number/object/nil values, array with
non-string element, URL-shape with dots-in-path treated as
literal). Resolver should be at 100%; floor at 95 leaves a
1-statement margin for future error-message refactors.
internal/auth/oidc/domain:
floor: 90
why: |
Bundle 2 Phase 1 — OIDCProvider + GroupRoleMapping domain.
Validation-heavy package; constructors + Validate methods
cover all canonical IdP shapes (Okta / Azure AD / Google
Workspace / Keycloak / Authentik / Auth0). Floor at 90 to
catch any future field that ships without a validator.
internal/auth/session:
floor: 90
why: |
Bundle 2 Phase 4 — session lifecycle service. Phase 4 spec
pins the floor at 90 because every fail-closed branch carries
a security invariant: HMAC-SHA256 cookie signing with a
LENGTH-PREFIXED canonical input (defeats the
`<a, bc>`-vs-`<ab, c>` concatenation collision attack on the
bare-concat form), v1. version-prefix lock, idle expiry,
absolute expiry, revocation, retired-but-in-retention key
success path, retired-past-retention failure path, CSRF
constant-time compare against the SHA-256-hashed copy on the
session row, optional IP/UA-bind defense-in-depth gates,
fail-fatal initial-key bootstrap. A regression in any one of
these branches is a security incident; the floor catches it
before the commit lands. The 15-case negative-test matrix in
service_test.go is the load-bearing harness; the in-memory
stubs of SessionRepo + SigningKeyRepo + AuditRecorder let the
state machine be exercised without the postgres testcontainer
overhead (which Phase 2's integration tests already cover).
internal/auth/session/domain:
floor: 90
why: |
Bundle 2 Phase 1 — Session + SessionSigningKey domain. Both
types ship Validate() with full invariant coverage: ID prefix
enforcement (ses-/sk-), expiry-order CHECK (absolute > idle >
created), CSRFTokenHash format pin (64 lowercase hex chars),
KeyMaterialEncrypted non-empty, retired-before-created
rejection, TenantID defaulting. Cookie naming constants are
pinned by TestCookieNamingConstants because the GUI's
web/src/api/client.ts will read `certctl_csrf` by string.
Floor at 90 to catch any future field that ships without a
validator.
internal/auth/breakglass:
floor: 90
why: |
Bundle 2 Phase 7.5 — break-glass admin service (Argon2id +
lockout state machine + constant-time-via-verifyDummy). Phase
13 Pre-merge audit: floor at 90 with no carve-out. Phase 7.5
spec ships the package at 91.5%, validated by 8 mandated
negatives + ~12 coverage-lift tests. Every fail-closed branch
is load-bearing for the security surface (default-OFF posture
only matters if every "disabled" path returns ErrDisabled
BEFORE any DB lookup; constant-time defense only matters if
every path goes through verifyDummy on the no-credential leg).
A regression that drops a fail-closed branch's coverage below
90 is a real security risk — gate trips, operator audits.
internal/auth/breakglass/domain:
floor: 90
why: |
Bundle 2 Phase 1 — BreakglassCredential domain. Argon2id PHC
format pinned ($argon2id$ prefix), MinPasswordLengthBytes (12)
+ MaxPasswordLengthBytes (256) constants pinned by dedicated
test, IsLocked(now) state machine helper. The package ships
at 100% coverage; floor at 90 is the standing-room floor for
any future field added without a validator.
internal/auth/user/domain:
floor: 90
why: |
Bundle 2 Phase 1 — User domain (federated-human identity).
OIDCSubject + OIDCProviderID unique-index per the Phase 2
schema, WebAuthnCredentials JSONB reserved for v3, Validate()
enforces every on-disk invariant. The package ships at 96.4%
coverage. Floor at 90 to catch any future field added without
a validator.
Phase 13 prompt explicitly enumerates internal/auth/user/ at
floor 90. The parent (non-domain) directory has no Go source —
the user upsert lives in internal/auth/oidc/service.go alongside
group resolution + role mapping (cohesive sequence within the
OIDC callback). Splitting upsertUser into a separate
internal/auth/user/ service package would harm cohesion without
adding test value; the domain layer's invariant coverage is
where the floor actually applies.

# Changelog
## v2.1.0 - Auth Bundle 1: RBAC primitive ⚠️
## Unreleased
### Tests
- **Vitest coverage for the 2026-05-10/11 GUI batch (Audit 2026-05-11 Fix 12).**
The original GUI-batch commit `661b6db` claimed `npx tsc --noEmit PASS`
but shipped no Vitest cases for the new surfaces. The regression-
prevention layer was missing — a future refactor of `KeysPage`'s
assign modal could silently drop scope_type handling, the LOW-1 demo
banner could be hidden by a stray predicate flip, the LOW-11 hide of
the delete button on default roles could disappear and let operators
click straight into a backend 409, and nothing would surface in CI.
This closure adds 35 new test cases across five files:
`web/src/pages/auth/UsersPage.test.tsx` (new, 8 cases pinning the
active/deactivated/reactivate flow + provider filter + empty state +
loading state), `web/src/pages/auth/AuthSettingsPage.test.tsx`
(extended +4 cases pinning the MED-12 runtime-config panel —
alphabetical sort, `(empty)` placeholder, 403 silent-hide),
`web/src/pages/auth/KeysPage.test.tsx` (extended +8 cases pinning
the HIGH-10 GUI half — scope_type=global/profile/issuer body shape,
expires_at omission vs RFC3339 promotion, whitespace-only scope_id
rejection, demo-anon row mutation-button hide),
`web/src/pages/auth/RoleDetailPage.test.tsx` (new, 9 cases pinning
the MED-8 scope picker + the LOW-11 default-role delete-button hide
via the `DEFAULT_ROLE_IDS` set against `r-admin` + `r-auditor`),
`web/src/components/AuthProvider.test.tsx` (new, 5 cases pinning the
LOW-1 demo-banner visibility predicate — `authType==='none' &&
!loading` — across happy/api-key/oidc/loading/rejected branches; the
rejected-fetch path keeps the banner visible because the catch
treats it as an old-server-fallback to demo-mode, and that behavior
is pinned here so a future change surfaces in the diff). 40/40
test-file-scoped pass; `tsc --noEmit` clean.
### Security
- **CSRF rotation on logout closes HIGH-2 fourth call site (Audit 2026-05-11 Fix 13).**
The HIGH-2 closure (`dev/auth-bundle-2`) documented four
`RotateCSRFTokenForActor` call sites: login completion (fresh by
construction), Assign/RevokeRole on role-mutation (wired), Logout, and
an explicit operator endpoint. The 2026-05-11 review verified only 3
of the 4 — Logout did NOT rotate the actor's sibling sessions
post-revoke, leaving a window where a token captured pre-logout
(browser DevTools, malicious extension, session-storage leak) could
be replayed against the user's other-device/other-browser sessions
until those sessions hit their own idle/absolute expiry.
`SessionMinter` interface extended with `RotateCSRFTokenForActor`;
`Logout` invokes it after `Revoke(sess.ID)` succeeds. The
`auth.session_revoked` audit row gains a `csrf_rotated` detail key
carrying the rotated count so SOC / SIEM can correlate logout events
with CSRF churn. The no-cookie + invalid-cookie 204 short-circuit
paths skip rotation (no session row to rotate against). 3 regression
tests in `internal/api/handler/auth_session_oidc_test.go` pin the
happy path + the two short-circuit branches. The explicit operator
endpoint (4) remains intentionally unbuilt — the three automatic
triggers (login + role-mutation + logout) cover the threat model;
operators who want a nuclear option can use the existing
`RevokeAllForActor` flow which forces re-login → fresh session →
fresh CSRF. **HIGH-2 fully closed across all four documented call
sites.**
- **Demo-mode residual-grants detector + cleanup endpoint + CI guard (Audit 2026-05-11 A-8).**
HIGH-12 (closure `b81588e`) added a fail-closed bind-address guard
that refuses startup when `CERTCTL_AUTH_TYPE=none` binds non-loopback
without `CERTCTL_DEMO_MODE_ACK=true`. The Phase 2 leg of that spec —
production-startup banner when `actor-demo-anon` has residual role
grants in `actor_roles` plus a CI guard banning new synthetic-admin
code paths — was deferred. This closure lands all three deferred
legs. (1) `cmd/server/preflight_demo_residual.go` runs after the DB
is open + audit service is constructed, before the HTTPS listener
starts; under any non-`none` auth type it queries `actor_roles` for
`actor-demo-anon` and emits a WARN log + `auth.demo_residual_grants_detected`
audit row when the row is present. The migration 000029 baseline
unconditionally seeds the `ar-demo-anon-admin` row at install time,
so EVERY production deploy will see this WARN on first boot — the
intended cutover workflow is documented at `docs/operator/security.md`.
(2) `POST /api/v1/auth/demo-residual/cleanup` is an admin-class
(`auth.role.assign`) cleanup endpoint that removes every
`actor-demo-anon` row from `actor_roles` and returns
`{"removed": <int64>}`; idempotent (a second call returns
`removed:0`), refuses 503 under `Auth.Type=none` (deleting the row
would break the demo path), audit-logs every invocation. (3) New
env var `CERTCTL_DEMO_MODE_RESIDUAL_STRICT` (default `false`)
pivots the WARN to fail-closed startup refusal for operators who
want a paranoid hostile-environment posture. (4) CI guard
`scripts/ci-guards/no-new-synthetic-admin.sh` pins the 17-entry
allowlist of source files that may reference the `actor-demo-anon`
literal; new runtime code paths that resolve to the synthetic actor
are rejected at PR time so the credibility gap stays closed. The
closure was framed as "credibility gap, not exploitable
vulnerability" — the residue requires a regression elsewhere in the
middleware chain to be exploitable. After this fix, the canonical
acquisition-readiness narrative ("RBAC primitive with no
synthetic-admin fallback") is fully true. Operator runbook at
`docs/operator/security.md#demo-to-production-cutover-audit-2026-05-11-a-8`.
- **OIDC provider "Test connection" panel (Audit 2026-05-11 Fix 09 — MED-5 GUI half).**
MED-5's backend dry-run endpoint (`POST /api/v1/auth/oidc/test`, gated
`auth.oidc.create`) shipped on `dev/auth-bundle-2` but had no GUI caller —
the `authOIDCTestProvider` function in `web/src/api/client.ts` was dead
code. Operators had to complete the create form blind, save, then click
"Refresh" to discover whether the issuer URL worked; failures left a
broken provider row in the database that had to be deleted before
retrying. New shared component
`web/src/pages/auth/OIDCTestConnectionPanel.tsx` calls the backend
against the live form state and renders a four-row status panel inline:
Discovery fetched, JWKS reachable, supported algs (warns when the IdP
advertises none), and RFC 9207 iss-parameter advertisement (informational
`·` glyph, not ✗, because the spec is SHOULD). Backend per-leg `errors[]`
flow into an inline bullet list. The panel is mounted in the
OIDCProvidersPage create modal AND the OIDCProviderDetailPage edit form —
the edit-form half is load-bearing for verifying IdP rotations (Keycloak
realm rename, Okta tenant move) without committing first. Run button is
disabled until the issuer URL is non-empty (whitespace-trimmed); the
component is read-only — safe to run repeatedly. 8 Vitest tests pin the
glyph-vs-glyph contract (✓/✗/⚠/·), the button-disabled-without-issuer
shape, and the test-id-suffix collision-prevention when the panel is
mounted twice on the same page.
- **OIDC JWKS health panel + Refresh-now button (Audit 2026-05-11 Fix 10 — MED-7 GUI half).**
MED-7's backend endpoint `GET /api/v1/auth/oidc/providers/{id}/jwks-status`
(commit `d85114f`) shipped the per-provider verifier counters on
`dev/auth-bundle-2` but the GUI never called it. The audit doc had
prematurely flipped the row to CLOSED; `authOIDCJWKSStatus` in the
API client was dead code. Operators investigating "why is login
failing for this IdP" couldn't see `last_refresh_at`,
`rejected_jws_count`, or `last_error` from the GUI — they had to
drop to curl. New shared component
`web/src/pages/auth/OIDCJWKSStatusPanel.tsx` queries the endpoint
via TanStack Query (30s `staleTime`, `retry: 0` so a 403 hides the
panel silently for callers without `auth.oidc.list`) and renders
six dt/dd rows: Last refresh (with `(never — cold cache)` sentinel
when the timestamp is empty), Refresh count, Rejected JWS count,
Last error (red treatment when non-empty, `(none)` sentinel
otherwise), RFC 9207 iss param ("supported by IdP" / "not
advertised"), and Current KIDs (`(not exposed — query jwks_uri
directly)` sentinel when the backend declines to expose the list).
A "Refresh now" button invokes the existing
`POST .../refresh` (RefreshKeys path) and invalidates the panel's
query so the freshly-updated counters render without a page
reload. The button is hidden for callers without `auth.oidc.edit`
via the panel's optional `canRefresh` prop. Mounted on
`OIDCProviderDetailPage.tsx` between the read-only field display
and the Actions section. 9 Vitest tests pin: loading state,
happy-path-all-six-rows, 403-hides-panel, refresh-invalidates-
query, refresh-failure-surfaces-inline-without-hiding-panel,
never-refreshed-cold-cache-sentinel, current-kids-empty-not-
exposed-sentinel, last-error-red-treatment, and canRefresh=false-
hides-the-button.
- **UsersPage sidebar nav entry (Audit 2026-05-11 Fix 11 — MED-11
discoverability).** The MED-11 closure shipped `UsersPage.tsx` + wired
the `/auth/users` route in `web/src/main.tsx`, but the sidebar
navigation never gained a corresponding entry. Operators reached the
federated-user-admin surface (used during compliance audits — "show
me last login for every IdP-federated user") only by knowing the URL.
A page that exists but isn't navigable is a half-finished page. New
Users entry under the Auth section in `web/src/components/Layout.tsx`
sits between Sessions and Roles (federated-identity grouping). Three
Vitest tests in `Layout.test.tsx` pin the link's presence, the
`/auth/users` destination, and the DOM ordering relative to Sessions
so a future refactor that re-orders or removes the entry surfaces in
the diff.
- **Scope-aware actor-role revoke (Audit 2026-05-11 A-4).**
HIGH-10 made it possible to grant the same role to the same actor at
multiple scopes (e.g. `r-operator` on `profile=p-acme` AND `profile=p-globex`)
via the unique constraint extension on `actor_roles`, but
`ActorRoleRepository.Revoke` ignored `(scope_type, scope_id)` and
unconditionally deleted every variant. Operators who wanted to drop
one scoped grant had to nuke them all and re-grant the remainder —
a race window where the actor's access was briefly different. The
`DELETE /v1/auth/keys/{id}/roles/{role_id}` endpoint now accepts
optional `?scope_type=` / `?scope_id=` query params that narrow the
revoke to a single variant; no-match returns 404. The legacy "revoke
every variant" semantic is preserved when the query params are
absent, so existing CLI / GUI buttons keep working unchanged. The
audit row's `details` payload records which mode fired so SOC / SIEM
can distinguish wide cleanups from targeted demotions. MCP tool
`certctl_auth_revoke_role_from_key` gains optional `scope_type` +
`scope_id` input fields with matching semantics. Documented in
`docs/operator/rbac.md` under "Revoke: legacy 'all variants' vs
scope-selective."
### Security (BREAKING — silent-elevation closure)
- **HIGH-10 actor-role scope is now enforced (Audit 2026-05-11 A-1).**
Pre-fix, `actor_roles.scope_type` / `scope_id` (added in migration 000043
by the HIGH-10 closure) were persisted by Grant + accepted on the handler
body + surfaced through the GUI/MCP — but the load-bearing
`EffectivePermissions` SQL never read them. A profile-scoped grant
silently elevated to global at authorization time. Canonical CRIT-5
lying-field shape, replicated. **The post-fix authorization narrows
correctly**: every existing `actor_roles` row with `scope_type != 'global'`
now takes effect.
> **Operator advisory:** if you used the HIGH-10 scope-bound role-grant
> API between commit `551812b` and the v2.1.0 tag (the column was
> populated but ignored), the grants were silently global. After
> upgrading, audit `SELECT actor_id, role_id, scope_type, scope_id FROM
> actor_roles WHERE scope_type != 'global'` and confirm the narrowing
> reflects intent. If an actor was granted a scoped role but expected
> global behavior, re-grant with `scope_type=global`.
### Security (BREAKING)
- **Federated-user deactivation now actually blocks login (Audit 2026-05-11 A-2).**
The MED-11 closure shipped `users.deactivated_at` + `DELETE /api/v1/auth/users/{id}`
+ cascade-session-revoke, but the column was a "lying field" three legs over: the
postgres user repository never SELECTed it (so `User.DeactivatedAt` always read
nil), the `Update` SQL never wrote it (so the handler's mutation was a no-op),
and the OIDC `upsertUser` path never checked it (so the next login under the
same `(provider, subject)` tuple re-minted a session and re-elevated the user).
The cascade-revoke remained correct for the current cookie only. **Operator
advisory: if you deactivated a federated user between the MED-11 closure
(Bundle 2 merge `dea5053`) and the v2.1.0 release tag, verify the user cannot
OIDC-log-in after upgrading — the column took no effect at login time before
this fix. If needed, re-run the deactivation against the upgraded server.**
Closure: `userColumns` + `scanUser` now read `deactivated_at` via `sql.NullTime`;
`Create` + `Update` write it explicitly; `upsertUser` returns the new
`ErrUserDeactivated` sentinel before mutating fields (preserves `last_login_at`
forensics on rejected logins); `classifyOIDCFailure` surfaces the rejection
as audit category `user_deactivated`. Self-deactivate guard on
`DELETE /api/v1/auth/users/{id}` returns HTTP 409 + audit row
`auth.user_deactivate_self_rejected` (prevents an admin from one-way-door
locking themselves out via the standard handler — break-glass remains the
recovery path). New inverse endpoint `POST /api/v1/auth/users/{id}/reactivate`
(gated `auth.user.deactivate` — reactivation is the inverse op, not a separate
privilege) clears `deactivated_at`; emits audit row `auth.user_reactivated`.
Sessions revoked at deactivation stay revoked across reactivation — the user
must complete a fresh OIDC login. GUI: `UsersPage.tsx` now renders a Reactivate
button on deactivated rows. CWE-862 (missing authorization at the user-state
boundary). SOC 2 CC6.3 + ISO 27001 A.9.2.6 compliance-table-flipping fix.
- **`__Host-` cookie prefix on all three auth cookies (Audit 2026-05-10 MED-14).**
The session cookie, CSRF cookie, and OIDC pre-login cookie are renamed from
`certctl_session` / `certctl_csrf` / `certctl_oidc_pending` to
`__Host-certctl_session` / `__Host-certctl_csrf` / `__Host-certctl_oidc_pending`
to gain browser-enforced subdomain-takeover protection (a `__Host-*` cookie can
only be set with `Path=/` + `Secure` + no `Domain` attribute, and the browser
rejects subdomain attempts to overwrite it). **Active sessions invalidate on
the rolling deploy that lands this change** — operators must re-authenticate
once after upgrading. The GUI's CSRF cookie reader was updated in lockstep.
See `docs/migration/oidc-enable.md` for operator-facing detail.
### Security
- **OIDC `allowed_email_domains` now editable in the GUI (Audit 2026-05-11 A-3).**
The backend gate that rejects logins whose email domain is outside the
configured allowlist landed in v2.1.0 (CRIT-5 closure, 2026-05-10), but the
GUI never exposed the field — GUI-driven operators had to use the API
directly to configure tenant isolation against multi-tenant IdPs (Auth0,
Azure AD common endpoint, Google Workspace). The OIDCProvidersPage create
modal and OIDCProviderDetailPage detail view now render a chip-style
multi-input with client-side validation that mirrors the backend rules
(no `@`, no whitespace, no wildcards, lowercase-only FQDNs). The read-only
view renders an explicit "any (no gate configured)" sentinel when the list
is empty so operators can tell "not configured" apart from "field is
invisible." A "Clear all" button on the edit form is gated by a confirm
dialog that warns about removing the tenant gate. **Operator advisory: if
you provisioned OIDC providers via the GUI between v2.1.0 and this fix,
verify `allowed_email_domains` matches your tenant policy — the field was
configurable only via API / MCP / direct SQL during that window.** Per-IdP
runbooks for multi-tenant IdPs in `docs/operator/oidc-runbooks/` already
documented the field; the GUI now matches.
- **Approval payload preview (Audit 2026-05-11 A-5).**
The MED-10 closure claim ("PARTIAL: raw JSON preview; diff library
deferred") was inaccurate — `ApprovalsPage.tsx` rendered no payload
at all, so approvers were clicking Approve / Reject without seeing
the change they were authorizing. That defeats the entire four-eyes
primitive: an approver who can't see what they're approving is
rubber-stamping. Each row now carries a Preview toggle that expands
an inline panel dispatching by kind: `profile_edit` shows a
field-level before/after diff (changed-only rows, red/green cells,
`(unset)` sentinel for added/removed fields); `cert_issuance` shows
a definition list of CN / SANs / profile / key algo / must-staple /
validity (catches the wildcard-against-corp-internal-profile attack
at review time); unknown kinds render a generic JSON preview for
forward-compat with future approval kinds. The base64-encoded JSON
payload is decoded via the new `decodePayload` helper; malformed
inputs render an explicit decode-error fallback — silent failure on
the payload preview is what produced this bug in the first place.
- **Strict pre-login UA/IP binding (Audit 2026-05-11 A-6).**
The MED-16 closure left a request-side empty-header bypass: when the
pre-login row carried a User-Agent or client-IP binding but the
`/auth/oidc/callback` request omitted the corresponding value, the
binding check was silently skipped. `curl` doesn't send User-Agent
by default; many programmatic clients omit it. An attacker who
acquired a pre-login cookie could replay it without the bound
header and bypass the RFC 9700 §4.7.1 defense. The check is now
strict-when-stored — an empty request-side value with a non-empty
stored binding rejects with HTTP 400 and the new audit failure
categories `prelogin_ua_missing` / `prelogin_ip_missing` (distinct
from the existing `*_mismatch` categories so SIEM rules can alert
specifically on bypass attempts). **Operator advisory:** environments
where the User-Agent is stripped in transit (some debug proxies, a
handful of CDN configurations) must set
`CERTCTL_OIDC_PRELOGIN_REQUIRE_UA=false` to keep logins working;
symmetric `CERTCTL_OIDC_PRELOGIN_REQUIRE_IP=false` exists for the
IP-side. The legacy-row compat window — pre-migration rows with no
stored binding — still passes through unchecked, but that window is
bounded by the 10-minute pre-login TTL.
- **OIDC provider Advanced fields are now editable in the GUI (Audit 2026-05-11 A-7).**
The MED-4 row had been DEFERRED to v3 with the rationale "backend
already accepts these fields." The verifier hit the GUI and found
that the read-only display claimed the values were editable, but the
edit form had no inputs — the save handler passed `provider.scopes`
/ `provider.groups_claim_path` / `provider.groups_claim_format` /
`provider.iat_window_seconds` / `provider.jwks_cache_ttl_seconds`
unchanged from the loaded object. Operators who wanted to bump the
IAT window or change the groups-claim path had to drop to curl /
MCP and trust the GUI's display matched what they'd set elsewhere.
Lying UX. The OIDCProviderDetailPage edit form now has a collapsible
Advanced section with five inputs (scopes as a space-separated text
field; groups-claim path; groups-claim format select with the
backend's `string-array` / `json-path` enum; IAT window number input
bounded 1–600; JWKS cache TTL number input with floor 60). Client-side
validation mirrors the backend `Validate` rules so common operator
mistakes (IAT > 600, JWKS TTL < 60, empty scopes, empty groups-claim-path)
reject inline instead of round-tripping a 400. The read-only `<dl>`
also gained the previously-invisible `jwks_cache_ttl_seconds` row.
- **Pre-login cookie Path widened from `/auth/oidc/` to `/` (Audit MED-14
follow-on).** Required to satisfy the `__Host-` prefix's `Path=/` rule. The
cookie lifetime is unchanged (10 minutes) and only the callback handler
consumes it; the wider path scope is harmless.
- **RFC 9207 `iss` URL parameter check on OIDC callback (Audit 2026-05-10
MED-17).** When the matched IdP's discovery doc advertises
`authorization_response_iss_parameter_supported: true`, certctl now requires
the `iss` query parameter on `/auth/oidc/callback` and enforces a
constant-time compare against the configured provider's `IssuerURL`. Mismatch
rejects with HTTP 400; the audit row's `failure_category` distinguishes
`iss_param_missing` / `iss_param_mismatch` (RFC 9207 leg) from the existing
`id_token_iss_mismatch` (in-token iss claim leg). Closes the mix-up-attack
defense for modern Keycloak, Authentik, and public-trust CAs that ship
RFC-9207 discovery. Providers that don't advertise support (the majority
today) keep pre-fix behavior — back-compat is preserved.
- **Auth GUI batch (Audit 2026-05-10 MED-4/7/8/10/11/12 + LOW-1/11/12 +
HIGH-10 GUI).** New backend endpoints land alongside their GUI
consumers: `GET /api/v1/auth/users` + `DELETE /api/v1/auth/users/{id}`
(auth.user.read / auth.user.deactivate; migration 000045 adds
`users.deactivated_at` plus the two new permissions); `GET
/api/v1/auth/runtime-config` (auth.role.assign) returning a sanitized
flat-map of deployed CERTCTL_* values (no secrets leaked — only
set/unset booleans and counts); `GET
/api/v1/auth/oidc/providers/{id}/jwks-status` (auth.oidc.list)
returning the per-provider verifier counters (refresh count, last
refresh / error timestamps, rejected JWS count, RFC 9207 iss-param
flag). New `UsersPage` lists federated identities + soft-deactivates.
`AuthSettingsPage` gains the runtime-config panel. `KeysPage`'s
assign-role modal now collects `scope_type` / `scope_id` /
`expires_at`. `RoleDetailPage`'s add-permission form gains the same
scope picker, and the Delete button is hidden on the 7 default
system roles (server already rejected, this is pure UX).
`AuthProvider` renders a sticky red demo-mode banner when
`auth_type=none`. `actor-demo-anon` rows on `KeysPage` already had
buttons disabled.
- **11 new MCP tools (Audit 2026-05-10 MED-13).** Approval workflow
(`certctl_approval_list` / `_get` / `_approve` / `_reject`), break-glass
credential admin (`certctl_breakglass_list` / `_set_password` /
`_unlock` / `_remove`), bootstrap status + consume
(`certctl_bootstrap_status` / `_consume`), and audit category filter
(`certctl_audit_list_with_category`). All route through the existing
HTTP client so server-side permission gates fire unchanged.
`certctl_bootstrap_consume`'s tool description carries an explicit
"NEVER WIRE THIS TO AUTONOMOUS OPERATION" warning — a leaked
bootstrap token mints a fresh admin API key bypassing every other
access-control gate, so the tool is for one-shot manual operator
invocation only.
- **JWKS auto-refresh on cache-miss (Audit 2026-05-10 MED-6).** When
the IdP rotates its signing key between pre-login + callback, the
cached JWKS no longer contains the kid referenced by the inbound ID
token's JWS header. Pre-fix, the verify failed with a generic error
and the operator had to manually call `POST
/api/v1/auth/oidc/providers/{id}/refresh`. The service now detects
the kid-not-in-cache shape (`isKidMismatchError`) and runs a
one-shot `RefreshKeys` (evict cache → re-fetch discovery + JWKS →
re-run alg-downgrade defense) before retrying the verify exactly
once. Bounded recovery: a second failure surfaces as
`ErrJWKSUnreachable` per the original branches; no retry loop. A
separate matcher (`isKidMismatchError`) is intentionally narrow
so generic signature failures don't trigger refresh.
- **OIDC provider test endpoint (Audit 2026-05-10 MED-5).** New
`POST /api/v1/auth/oidc/test` dry-runs an OIDC provider configuration
without persisting: fetches the discovery doc, runs the alg-downgrade
defense, detects RFC 9207 iss-parameter advertisement, and confirms
JWKS reachability. Returns `TestDiscoveryResult{discovery_succeeded,
jwks_reachable, supported_alg_values, iss_param_supported, errors[]}`
so the GUI (forthcoming) can render per-check status rows. Per-leg
failures ride in the response body's `errors` array; only a malformed
request body trips 400. Gate: `auth.oidc.create`. Audit row
`auth.oidc_provider_tested` carries the success/failure summary.
- **Pre-login UA / source-IP binding on OIDC callback (Audit 2026-05-10
MED-16).** RFC 9700 §4.7.1 defense against stolen-pre-login-cookie replay
by a different browser / source. Migration `000044_prelogin_uaip` adds
`client_ip` + `user_agent` to `oidc_pre_login_sessions`; values captured at
`/auth/oidc/login` are constant-time compared at `/auth/oidc/callback`.
Mismatches return HTTP 400 with audit `failure_category` =
`prelogin_ua_mismatch` or `prelogin_ip_mismatch`. Two operator escape
hatches: `CERTCTL_OIDC_PRELOGIN_REQUIRE_UA` and
`CERTCTL_OIDC_PRELOGIN_REQUIRE_IP` (both default `true`) — operators on
enterprise proxies that rewrite UA, or dual-stack v4/v6 environments where
source IP routinely flips, can disable the affected leg. The binding column
is persisted even when enforcement is off, so retroactive forensics remain
possible. Empty values on either side pass through (rolling-deploy +
headless-proxy compat).
## v2.1.0 - Auth Bundles 1 + 2: RBAC primitive + OIDC SSO + sessions ⚠️

@@ -34,6 +448,27 @@
What else changed in v2.1.0:
- **Audit 2026-05-10 CRIT-1 closure — wire-layer RBAC enforcement.**
The Bundle 1 + Bundle 2 audit surfaced that the permission catalogue
was enforced on ~24 admin-only routes only; the bulk of state-changing
routes (`POST /api/v1/certificates`, `PUT /api/v1/profiles/{id}`,
`DELETE /api/v1/issuers/{id}`, `POST /api/v1/agents/{id}/csr`, even
`POST /api/v1/auth/roles` + `POST /api/v1/auth/keys/{id}/roles`) had
no `rbacGate` wrap. A `r-viewer` Bearer was essentially `r-admin`
minus five fine-grained verbs at the wire layer (CWE-862). This
release wraps every state-changing + read endpoint with
`rbacGate` (global scope) or `rbacGateScoped` (per-profile / per-
issuer scope-bound grants), and adds an AST-level CI guard
(`TestRouterRBACGateCoverage`) that fails when a new route is
registered without enforcement. Catalogue extended via migration
000039 with 30 permissions covering `cert.edit`, `job.*`,
`approval.*`, `policy.*`, `team.*`, `owner.*`, `notification.*`,
`discovery.*`, `network_scan.*`, `healthcheck.*`, `digest.*`,
`verification.*`, `stats.read`, `metrics.read`. **AUDIT YOUR
KEYS** (the scope-down call-out above) now translates to real
reduction in blast radius. Auditor pin preserved at exactly
`{audit.read, audit.export}`.
- **RBAC primitive shipped.** `tenants`, `roles`, `permissions`,
`role_permissions`, `actor_roles` tables (migration 000029); 33-permission
canonical catalogue; 7 default roles (`admin`, `operator`, `viewer`,

`phase12_protocol_allowlist_test.go` AST scan all guard against
accidentally wrapping ACME / SCEP / EST / OCSP / CRL routes in
`rbacGate`.
- **Bundle 2 (OIDC + sessions) starts after Bundle 1 lands on
master.** Roadmap entry remains in `cowork/auth-bundle-2-prompt.md`.
- **Bundle 2: OIDC + sessions + back-channel logout + break-glass.**
Auth Bundle 2 ships in the same v2.1.0 release. Operators get OIDC
SSO support for Keycloak / Authentik / Okta / Auth0 / Microsoft
Entra ID / Google Workspace (via Keycloak broker), HMAC-signed
session cookies with idle/absolute timeouts + CSRF defense,
back-channel logout per OpenID Connect Back-Channel Logout 1.0,
and a default-OFF break-glass admin path with Argon2id passwords
for SSO-broken incidents. API-key auth keeps working unchanged
alongside; existing automation needs no changes. Migration walkthrough
at [`docs/migration/oidc-enable.md`](docs/migration/oidc-enable.md);
per-IdP setup guides at
[`docs/operator/oidc-runbooks/index.md`](docs/operator/oidc-runbooks/index.md).
- **OIDC token validation pinned at three layers.** Algorithm
allow-list (RS256/RS512/ES256/ES384/EdDSA only) with HS-family + `none`
rejected at the service-layer sentinel; IdP-downgrade-attack defense
at provider creation AND every JWKS RefreshKeys (intersects the IdP's
advertised `id_token_signing_alg_values_supported` against the allow-
list, rejects providers that advertise weak algs even before any
token is signed); OIDC Core §3.1.3.7 re-verification of `iss` /
`aud` / `azp` / `at_hash` (REQUIRED-when-access_token-present per
Phase 3 tightening of the spec MAY → MUST) / `exp` / `iat` window
/ `nonce` constant-time-compare. PKCE-S256 mandatory; `plain`
rejected. Single-use state + nonce via atomic `DELETE...RETURNING`
on consume.
- **Session cookies use length-prefixed HMAC.** The cookie wire format
is `v1.<session_id>.<signing_key_id>.<base64url-no-pad(HMAC-SHA256)>`
with HMAC input `len:sid:len:kid` (NOT bare-concat) to defeat
concatenation collisions. `HttpOnly` + `Secure` + `SameSite=Lax`
default; `SameSite=Strict` configurable via `CERTCTL_SESSION_SAMESITE`.
Idle timeout 1h / absolute 8h defaults; scheduler GC sweeps expired
rows hourly. Signing keys rotate via the new `RotateSigningKey`
primitive; the old key stays valid for `CERTCTL_SESSION_SIGNING_KEY_RETENTION`
(default 24h) so existing cookies validate during rollover.
- **CSRF defense via double-submit-cookie + hashed-token-on-row.**
Plaintext CSRF token in the JS-readable `certctl_csrf` cookie
(intentionally `HttpOnly=false` for the GUI to echo into the
`X-CSRF-Token` header); SHA-256 hash on the session row;
`subtle.ConstantTimeCompare` in the new `CSRFMiddleware`. API-key
actors are CSRF-exempt (no session row in context).
- **OIDC `client_secret` encrypted at rest.** AES-256-GCM v3 blob
format (magic 0x03 + salt(16) + nonce(12) + ciphertext+tag) using
the existing `CERTCTL_CONFIG_ENCRYPTION_KEY`. Encryption invariant
pinned by an integration test asserting ciphertext != plaintext +
v3 blob shape + round-trip recovery + wrong-passphrase fails.
- **OIDC first-admin bootstrap.** New `CERTCTL_BOOTSTRAP_ADMIN_GROUPS`
+ `CERTCTL_BOOTSTRAP_OIDC_PROVIDER_ID` env vars: the first
OIDC-authenticated user with a matching group claim becomes admin
per tenant. Coexists with the Bundle 1 env-var-token bootstrap;
the admin-existence probe ensures only one wins. Audit row
(`bootstrap.oidc_first_admin`) on every grant.
- **Break-glass admin (default-OFF).** New `CERTCTL_BREAKGLASS_ENABLED`
env var (default `false`). When enabled, the local Argon2id-password
admin path bypasses OIDC + group-claim layers — intended ONLY for
SSO-broken incidents. Argon2id with OWASP 2024 params (m=64 MiB,
t=3, p=4); lockout after 5 failures (configurable); constant-time
across all failure paths via `verifyDummy`; surface invisibility
(HTTP 404 on every endpoint when disabled, NOT 403). WARN log at
server boot when enabled. WebAuthn/FIDO2 second factor pairing on
the v3 roadmap (Decision 12).
- **GUI: OIDC Providers + Group → Role Mappings + Sessions + login
buttons.** Four new pages under `/auth/*` consume the Bundle 2 API
surface. Login page renders one "Sign in with X" button per
configured OIDC provider (in addition to the API-key form, which
remains as a fallback for Bearer-mode + break-glass paths). Sessions
page exposes own-sessions + admin all-actors view. Every actionable
element is permission-gated server-side via `auth.oidc.*` and
`auth.session.*` perms; client-side hide is UX layer. Logout button
in the sidebar fires `POST /auth/logout` to clear the session
server-side before redirecting to login.
- **MCP server gains 11 OIDC + session tools.** `certctl_auth_list_oidc_providers`,
`_get_oidc_provider`, `_create_oidc_provider`, `_update_oidc_provider`,
`_delete_oidc_provider`, `_refresh_oidc_provider`,
`_list_group_mappings`, `_add_group_mapping`, `_remove_group_mapping`,
`_list_sessions`, `_revoke_session`. Operator-facing MCP tool count
goes 12 (Bundle 1 RBAC) → 23 across the auth surface. Total MCP
tool count: `grep -cE 'mcp\.AddTool\(' internal/mcp/tools*.go` ≈ 150.
- **Per-IdP runbooks: 6 production-tier setup guides** at
`docs/operator/oidc-runbooks/`. Each runbook follows a consistent
five-section layout (Prerequisites / IdP-side config / certctl-side
config / Verification / Troubleshooting + Validation checklist with
operator sign-off line). Keycloak is the canonical reference;
Authentik / Okta / Auth0 / Entra ID / Google Workspace document the
IdP-specific deltas (Auth0's namespaced custom claims; Entra ID's
group OBJECT IDs; Google Workspace's missing-groups-claim limitation
+ the recommended Keycloak broker pattern).
- **Threat model extended.** [`docs/operator/auth-threat-model.md`](docs/operator/auth-threat-model.md)
ships 5 new "Defenses Bundle 2 ships" subsections + 8 new threat-
catalogue subsections (OIDC token forgery / session hijacking / IdP
compromise / back-channel logout failure modes / group-claim
manipulation / bootstrap risks / break-glass risks / token-leak
hygiene). 6 new SQL-shaped operator-facing checks. New "Threats
Bundle 2 does NOT close" section enumerating the 8 v3-backlog items
(WebAuthn / JIT elevation / SAML / multi-tenant activation /
HSM-FIPS / OIDC RP-initiated logout / Playwright / per-IdP
external-tester sign-off).
- **Performance baselines documented.** [`docs/operator/auth-benchmarks.md`](docs/operator/auth-benchmarks.md)
ships four benchmarks with measured baselines on a 4 vCPU /
8 GiB / Postgres 16 / Go 1.25 floor: `BenchmarkSession_SteadyState`
p99 5 µs (target < 1 ms; 200× under), `BenchmarkSession_ColdProcess`
p99 7.1 ms (target < 10 ms), `BenchmarkOIDC_SteadyState` p99 1.5 ms
(target < 5 ms), `BenchmarkOIDC_ColdCache` operator-runs against
live Keycloak via `make benchmark-auth-coldcache`.
- **Standards + RFC implementation table.** [`docs/reference/auth-standards-implemented.md`](docs/reference/auth-standards-implemented.md)
ships 13 RFC / standard rows + 14 CWE rows with concrete file paths
+ negative-test anchors per row. NOT a compliance-mapping doc per
the operator's 2026-05-05 retired-compliance-docs decision; the
doc explicitly says "build the framework mapping yourself against
the rows here using the framework-mapping methodology your audit
firm prescribes; this project does not own that mapping."
- **Coverage gates held at floor 90 across all four Bundle 2
packages.** `internal/auth/oidc/` 93.7%, `internal/auth/session/`
94.9%, `internal/auth/breakglass/` 91.5%, `internal/auth/user/domain/`
96.4%. NO held-low-with-rationale entry — the Phase 13 prompt's
anti-Bundle-1-mistake rule held. Bundle 1's existing 85% floors
for `internal/auth/` + `internal/service/auth/` stay 85
(already-shipped-and-accepted) per the prompt's explicit
inheritance rule.
- **Multi-tenant query CI guard.** New `scripts/ci-guards/multi-tenant-query-coverage.sh`
(ratchet-style, baseline 32 at v2.1.0 close): greps every
SELECT/UPDATE/DELETE in `internal/repository/postgres/` against
10 tenant-aware tables, fails on regression OR improvement (forces
the operator to lift / lower the baseline visibly). Forward-compat
protection so a future Bundle 3 / managed-service multi-tenant
activation can flip the switch without finding silent
tenant-data-leak bugs in shipped queries.
- **Phase 10 Keycloak testcontainers integration test.** New build-tag-
gated suite at `internal/auth/oidc/testfixtures/` + `integration_keycloak_test.go`
drives the full OIDC flow against a live Keycloak container booted
by testcontainers-go. 5-test matrix: discovery + JWKS load, full
PKCE auth-code happy path with HTTP form scraping, logout-revokes-
session, JWKS rotation, unmapped-groups-fails-closed. Reuses one
container across the matrix to amortize the 60-90s boot. Optional
Okta smoke test (build-tagged `integration && okta_smoke`) for live
tenant validation. New Makefile targets: `make keycloak-integration-test`
+ `make okta-smoke-test` + `make benchmark-auth-coldcache`.
- **OpenAPI surface extended.** New `cookieAuth` security scheme
(apiKey/cookie/`certctl_session`) alongside the existing
`bearerAuth`. 13 new Bundle 2 endpoints across the OIDC + session
+ group-mapping CRUD surface; 4 break-glass endpoints with
surface-invisibility framing. The N-bundle-2-security-empty-preserved
CI guard locks the `security: []` opt-out count at ≥ 14 so existing
public endpoints stay public.
- **Bundle-1-only compat regression CI guard.** New
`scripts/ci-guards/bundle-1-compat-regression.sh` asserts the
load-bearing invariants that protect the Bundle-1-only-deploy
case (session middleware defers-to-next, CSRF passthrough on
missing session row, ChainAuthSessionThenBearer wired, public
OIDC routes in AuthExempt allowlist, AuthInfo guards on
OIDCProvidersResolver != nil). Sibling
`bundle-1-to-2-upgrade-regression.sh` asserts the upgrade-path
invariants (migrations 000034..000038 are CREATE TABLE IF NOT EXISTS
+ BEGIN/COMMIT-wrapped + no DROP TABLE / ALTER...DROP COLUMN
against 19 protected Bundle-1 tables + ON CONFLICT DO NOTHING on
permission seed).
Migration ordering, idempotency, and downgrade are documented in
[`docs/migration/api-keys-to-rbac.md`](docs/migration/api-keys-to-rbac.md).
The threat model + compliance mapping live at
[`docs/migration/api-keys-to-rbac.md`](docs/migration/api-keys-to-rbac.md)
(API-key → RBAC, Bundle 1) and [`docs/migration/oidc-enable.md`](docs/migration/oidc-enable.md)
(API-key → OIDC, Bundle 2). The threat model lives at
[`docs/operator/auth-threat-model.md`](docs/operator/auth-threat-model.md).

// Audit 2026-05-11 A-8 — demo-mode residual-grants detector. Closes the
// deferred Phase 2 leg of HIGH-12 (cowork/auth-bundles-fixes-2026-05-10/
// 11-high-12-demo-mode-guard.md). The HIGH-12 closure (`b81588e`) added
// the fail-closed bind-address guard at config.Validate; the deferred
// leg here adds a startup-time WARN (or strict refuse-startup) when
// `actor-demo-anon` has live role grants under a non-`none` auth type.
//
// Why this matters: migration 000029 unconditionally seeds the
// `ar-demo-anon-admin` row granting r-admin to actor-demo-anon. The
// row is dormant under auth_type=api-key|oidc (the middleware chain
// never injects the synthetic actor as the request principal), but
// it represents a security debt: any future regression in the
// middleware chain (a misrouted CORS preflight, a fallback in a new
// auth-exempt route) that resolves to actor-demo-anon would re-elevate
// to admin. The canonical acquisition-readiness narrative — "we have
// an RBAC primitive with no synthetic-admin fallback" — requires this
// row to be either gone or explicitly acknowledged.

# Enable OIDC SSO on a Bundle-1-merged deployment
> Last reviewed: 2026-05-10
This guide walks an operator already running certctl with Bundle 1 (RBAC primitive on top of API-key auth) through enabling OIDC SSO from Bundle 2. The path is additive: API-key auth keeps working unchanged; OIDC sits alongside as a second authentication surface for human users.
If you are upgrading from a pre-Bundle-1 deployment, finish [`api-keys-to-rbac.md`](api-keys-to-rbac.md) first. If you have not deployed certctl at all, start with [`getting-started/quickstart.md`](../getting-started/quickstart.md). For the canonical mental model + per-flow threat coverage, see [`security.md`](../operator/security.md) and [`auth-threat-model.md`](../operator/auth-threat-model.md).
## What "enable OIDC" gives you
After this migration:
- Human operators can log in via the OIDC button on the certctl login page (one button per configured IdP).
- The IdP authenticates the user; certctl validates the returned ID token, mints a session cookie, and redirects to the dashboard.
- IdP groups → certctl roles are operator-configured (e.g. `engineering@example.com` → `r-operator`).
- Every login emits an audit row (`auth.oidc_login_succeeded`) attributing the action to the federated user, NOT to a shared API key.
- The first user from a configured admin group (when `CERTCTL_BOOTSTRAP_ADMIN_GROUPS` is set) becomes admin per tenant; one-shot per the admin-existence probe.
What does NOT change:
- API keys keep working. Existing automation continues to authenticate via `Authorization: Bearer` exactly as before.
- The break-glass admin path (Phase 7.5) stays default-OFF.
- The auditor split + approval workflow + RBAC primitive are unchanged.
## Pre-requisites
**On certctl side:**
- Server build ≥ v2.1.0 (the post-Bundle-2 master). Confirm via `curl https://<your-host>:8443/api/v1/version`.
- `CERTCTL_CONFIG_ENCRYPTION_KEY` set in the server environment. This is the passphrase that encrypts the OIDC `client_secret` at rest. Use a stable, secrets-manager-stored value at least 32 random bytes long. **The server refuses to start if the key is missing AND any source='database' rows already exist** (per Bundle B / M-001 / CWE-311 closure). Set this before doing anything else.
- An admin actor available to drive the configuration. The actor needs the `auth.oidc.create` + `auth.oidc.edit` permissions; `r-admin` carries both by default. Get one via the day-0 bootstrap path if you don't have one yet.
- HTTPS-only control plane (post-v2.2 milestone — this is the default). The OIDC redirect URI MUST be `https://`.
**On IdP side:**
- A Keycloak / Authentik / Okta / Auth0 / Entra ID / Google Workspace tenant where you can register an OIDC application. Free dev tiers work for evaluation. See the per-IdP runbook at [`oidc-runbooks/index.md`](../operator/oidc-runbooks/index.md).
- Network reachability from certctl-server to the IdP's `/.well-known/openid-configuration` discovery endpoint. The certctl service fetches discovery + JWKS at provider creation and at every `RefreshKeys` call.
## Step-by-step
### 1. Pin `CERTCTL_CONFIG_ENCRYPTION_KEY`
If your deployment already has it set (the Bundle B M-001 fail-closed gate enforces this for any source='database' issuer/target row), skip this step. If you don't:
```bash
# Generate a 32-byte random key + base64-encode it.
openssl rand -base64 32 > /etc/certctl/config-encryption-key
chmod 600 /etc/certctl/config-encryption-key
```
Then make the server consume it at boot:
```bash
# In your environment, systemd unit, k8s Secret, etc.
export CERTCTL_CONFIG_ENCRYPTION_KEY="$(cat /etc/certctl/config-encryption-key)"
```
Restart the server. Confirm the boot log does NOT show the `ErrEncryptionKeyRequired` warning. If it does, the server refuses to start because there's pre-existing source='database' material that needs to be re-sealed; see the pre-Bundle-B migration notes for re-encryption flow.
### 2. Pick an IdP runbook + complete the IdP-side configuration
Pick the runbook for your IdP and do EVERYTHING in its IdP-side section. The runbooks are at [`docs/operator/oidc-runbooks/`](../operator/oidc-runbooks/index.md). What you need from the runbook before continuing here:
- The IdP's discovery URL (the `iss` value certctl will validate against).
- An OIDC client ID + client secret. Save the secret; you'll paste it into certctl in step 3.
- At least one IdP group with the users who should be allowed to log in. The runbook walks the group-claim mapper config.
- The IdP-side group claim shape — most IdPs emit `string-array` under a `groups` key, but Auth0 uses namespaced URL keys (`https://your-namespace/groups`) and Entra ID emits group OBJECT IDs (GUIDs) instead of names. The runbook calls out the per-IdP shape.
### 3. Configure the certctl-side OIDC provider
Via the GUI (recommended for first-time setup):
1. Sign in as an admin actor.
2. Navigate to **Auth → OIDC Providers** in the sidebar.
3. Click **Configure provider**.
4. Fill in the form using the values from step 2's runbook.
5. Click **Save**.
If the discovery doc fetch fails, the modal surfaces the error inline. Most-common cause: a typo in the issuer URL.
Or via the CLI / MCP:
```bash
curl -X POST https://<your-certctl-host>:8443/api/v1/auth/oidc/providers \
-H "Authorization: Bearer ${CERTCTL_API_KEY}" \
-H "Content-Type: application/json" \
-d '{
"name": "Keycloak",
"issuer_url": "https://keycloak.example.com/realms/certctl",
"client_id": "certctl",
"client_secret": "<paste-the-secret>",
"redirect_uri": "https://certctl.example.com:8443/auth/oidc/callback",
"groups_claim_path": "groups",
"groups_claim_format": "string-array",
"scopes": ["openid", "profile", "email"],
"iat_window_seconds": 300,
"jwks_cache_ttl_seconds": 3600
}'
```
The MCP equivalent (`certctl_auth_create_oidc_provider`) accepts the same JSON shape.
### 4. Add the group → role mappings
Empty mapping list = nobody can log in via this provider (the fail-closed contract; pinned by `ErrGroupsUnmapped`). Add at least one mapping BEFORE announcing the SSO endpoint to users.
Via the GUI: **Auth → OIDC Providers → <provider> → Group → role mappings → Add**.
Via the API:
```bash
curl -X POST https://<your-certctl-host>:8443/api/v1/auth/oidc/group-mappings \
-H "Authorization: Bearer ${CERTCTL_API_KEY}" \
-H "Content-Type: application/json" \
-d '{
"provider_id": "<provider-id-from-step-3>",
"group_name": "engineering@example.com",
"role_id": "r-operator"
}'
```
A typical setup adds two or three mappings: `engineers → r-operator`, `viewers → r-viewer`, optionally `admins → r-admin`. For Entra ID, use group object IDs (GUIDs) NOT names; for Auth0, use the bare group name from inside the namespaced claim array.
### 5. (Optional) Configure first-admin bootstrap
If your deployment has no admin actor yet AND you want the first OIDC-authenticated user from a specific group to become admin (instead of using the env-var-token bootstrap path), set:
```bash
export CERTCTL_BOOTSTRAP_ADMIN_GROUPS=admins
export CERTCTL_BOOTSTRAP_OIDC_PROVIDER_ID=<provider-id-from-step-3>
```
Restart the server. The first user with the `admins` group claim from that provider becomes admin on login per tenant. Subsequent logins go through normal group-role mapping. Audit row on every grant (`bootstrap.oidc_first_admin`).
If you already have an admin actor (likely — you needed one to run step 3), the bootstrap hook silently falls through to normal mapping; no harm done. The probe is one-shot per tenant and can't double-grant.
### 6. Verify with a single test user
Before announcing the SSO endpoint to your users, verify the full login flow with a test user from your IdP:
1. Open `https://<your-certctl-host>:8443/login` in a fresh incognito window.
2. The page should render `Sign in with <provider>` button(s) above the API-key form. If not, check that `getAuthInfo` is returning the `oidc_providers` field — `curl https://<your-host>:8443/api/v1/auth/info` should show the configured provider(s).
3. Click the provider button. The browser redirects to the IdP, you authenticate, and the IdP redirects back. You should land on the certctl dashboard.
4. Navigate to **Auth → Sessions**. You should see a row with your own actor ID and the current timestamp.
5. Confirm the audit row:
```bash
curl https://<your-host>:8443/api/v1/audit?category=auth \
-H "Authorization: Bearer ${CERTCTL_API_KEY}" \
| jq '.events[] | select(.action == "auth.oidc_login_succeeded")'
```
You should see a row attributed to the federated user with `details.provider_id` matching your configuration.
If any step fails, see the **Troubleshooting** section below.
### 7. Announce the SSO endpoint
Once step 6 passes, the SSO endpoint is operational. Tell your users to log in via `https://<your-host>:8443/login` and click the provider button. API-key auth continues to work for automation; the two paths coexist.
Optional GUI hardening:
- If you want the API-key form hidden once OIDC is configured, the operator can add a frontend feature flag in a follow-on commit. Default behavior keeps both paths visible (the API-key form stays for break-glass + Bearer-mode deploys).
- If you want to revoke a user's session immediately (e.g. an employee left), use **Auth → Sessions → All actors (admin) → <user> → Revoke**. The next request from that user's browser fails 401.
## Rollback
If you need to disable OIDC:
1. Delete every group-role mapping for the provider:
```bash
# GUI: Auth → OIDC Providers → <provider> → Group → role mappings → Remove (each)
```
2. Delete the OIDC provider:
```bash
# GUI: Auth → OIDC Providers → <provider> → Delete (type-confirm-name dialog)
```
The server returns HTTP 409 if any user has an authenticated session minted via this provider; revoke those sessions first.
3. The `Sign in with <provider>` button disappears from the login page on the next `getAuthInfo` round-trip (typically the next page load).
4. Existing sessions continue to work until idle/absolute expiry. To force-revoke them, **Auth → Sessions → All actors (admin) → revoke each row**.
API-key auth continues to work throughout this rollback; you do not need to re-bootstrap or change any other configuration.
## Troubleshooting
**"Discovery doc fetch failed" at provider creation.**
The most common cause is a typo in the issuer URL. Curl the URL manually:
```bash
curl -v https://<idp-host>/<path>/.well-known/openid-configuration
```
If that returns 404, fix the issuer URL.
**"IdP downgrade-attack defense" rejected provider creation.**
Your IdP advertises HS256/HS384/HS512 or `none` in `id_token_signing_alg_values_supported`. Configure the IdP to advertise only RS256 / RS512 / ES256 / ES384 / EdDSA before re-creating the provider in certctl. The relevant runbook section walks this.
**Login redirects to IdP, user authenticates, but the callback redirects back to `/login` with "no roles assigned".**
The user authenticated successfully but their groups didn't match any configured mapping (`ErrGroupsUnmapped`). Check:
- The user is a member of the IdP group you mapped.
- The group-claim mapper is configured correctly at the IdP (the runbook walks per-IdP).
- The group name in your certctl mapping exactly matches what the IdP emits — case-sensitive, no leading slash for Keycloak full-path-OFF.
Decode the ID token at jwt.io against the IdP's JWKS to see exactly what's in the `groups` claim.
**`ErrIssuerMismatch` even though the discovery doc looks correct.**
The `iss` claim in the ID token must match `OIDCProvider.IssuerURL` byte-for-byte. Some IdPs include / omit a trailing slash; check the per-IdP runbook section on `iss` formatting.
**`oidc: pre-login session not found or already consumed`.**
The user clicked the OIDC login button, then the browser tab idled past the 10-minute pre-login TTL OR the user opened the IdP login in a new tab and consumed the row from the first one. Have them retry from the login page.
**`oidc: state parameter mismatch (replay or forgery)`.**
Either the user double-submitted a callback URL (clicked it twice from email or browser history), or a CSRF attempt. The pre-login row is single-use; second consumption returns `ErrPreLoginNotFound`. Have them retry from the login page.
**`Sessions revoked but the user can still hit the API.`**
Check the Phase 4 session contract: the cookie is HMAC-validated on every request, but the actual database row is what `Revoke` deletes. If your reverse proxy is caching the response or the `certctl_session` cookie wasn't actually cleared on the client, the cookie hits the server's session middleware which returns 401 on the missing-row lookup. The middleware never serves stale data; the issue is upstream of certctl in this case.
**JWKS rotation: an IdP rotated its signing key and existing users start failing login.**
Click **Refresh discovery cache** on the OIDC provider detail page (or `POST /api/v1/auth/oidc/providers/<id>/refresh`). The certctl service re-fetches discovery + JWKS. New tokens validate immediately. The Phase 10 integration test exercises this drill end to end.
**Database row count drift.**
After OIDC is live, expect to see new rows under:
- `oidc_providers` (one per configured provider)
- `group_role_mappings` (one per configured mapping)
- `users` (one per first OIDC-authenticated user; certctl auto-upserts on login)
- `sessions` (one per logged-in browser session; idle 1h / absolute 8h GC)
- `session_signing_keys` (one active + retained-history rows post rotation)
- `oidc_pre_login_sessions` (transient; 10-minute TTL, scheduler-GC'd)
All ten of these tables are tenant-scoped (`tenant_id` column); single-tenant deployments use the seeded `t-default` tenant.
## What you can do next
- Run [`docs/operator/oidc-runbooks/<your-idp>.md`](../operator/oidc-runbooks/index.md) end to end to fill in the validation checklist + sign-off line.
- Read [`docs/operator/auth-benchmarks.md`](../operator/auth-benchmarks.md) for the steady-state + cold-cache performance baselines.
- Review the [`auth-threat-model.md`](../operator/auth-threat-model.md) Bundle 2 sections to understand the failure modes the OIDC + sessions surface defends against.
- Schedule a rotation reminder for the OIDC `client_secret` (typically 6-12 months; the IdP doesn't auto-rotate it). Edit the provider via the GUI when the time comes; leaving `client_secret` blank in the edit form preserves the existing ciphertext, providing a value rotates.
## `__Host-` cookie rename (Audit 2026-05-10 MED-14, BREAKING)
Post-Bundle-2 deploys carrying the 2026-05-10 audit-fix wave include a wire-format change to the three auth cookies: they now carry the `__Host-` prefix. The cookie names are:
- `__Host-certctl_session` (was `certctl_session`)
- `__Host-certctl_csrf` (was `certctl_csrf`)
- `__Host-certctl_oidc_pending` (was `certctl_oidc_pending`)
The rename gains browser-enforced subdomain-takeover defense: a `__Host-*` cookie can only be set with `Path=/` + `Secure` + no `Domain` attribute, and the browser rejects any subdomain attempt to overwrite it. The protection is free (the existing cookies already met the prerequisites) but the wire-format change means:
- **Every active session is invalidated by the deploy that lands this change.** Operators see one re-authentication prompt; subsequent logins issue the new `__Host-*`-prefixed cookie.
- **The pre-login cookie's Path widens from `/auth/oidc/` to `/`** — required by the `__Host-` prefix. The cookie lifetime is unchanged (10 minutes) and is only ever consumed by the callback handler; the wider path scope is harmless.
- **No operator action required beyond accepting the one-time re-login window.** The GUI's CSRF cookie reader was updated in lockstep; existing bookmarked deep links work without modification.
If you have GUI customizations that read `document.cookie` directly, update them to look for `__Host-certctl_csrf` (the lookup in `web/src/api/client.ts` is the in-tree reference).

# Authentication performance benchmarks
> Last reviewed: 2026-05-10
This document records the four Auth Bundle 2 / Phase 14 performance benchmarks: session validation (steady-state and cold-process) plus OIDC token validation (steady-state and cold-cache). Numbers below are the as-measured baseline at the Bundle 2 close; future regressions are caught when the operator re-runs `make benchmark-auth` and the per-quantile values move outside the documented bounds.
For the threat model that motivates each path's structure, see [`auth-threat-model.md`](auth-threat-model.md). For the OIDC-side validation pipeline these benchmarks exercise, see [`internal/auth/oidc/service.go`](../../internal/auth/oidc/service.go) and [`internal/auth/session/service.go`](../../internal/auth/session/service.go).
## Hardware floor
The numbers below are bounded by this configuration. Operators on weaker hardware (Raspberry Pi 4, low-tier VPS) should re-run + record their own measurements; operators on faster hardware will see proportionally lower numbers.
| Component | Spec |
|---|---|
| CPU | 4 vCPU (linux/arm64; ARM Neoverse-N1 class) |
| RAM | 8 GiB |
| Postgres | 16-alpine in same docker network as certctl-server (cold-process simulation: deterministic 1ms RTT per repo call) |
| Go runtime | 1.25.10 |
| Disk | NVMe SSD (CI-runner-equivalent) |
GitHub-hosted Ubuntu runners satisfy this floor. The Phase 14 baselines below were captured on a `linux/arm64` 4-vCPU sandbox at 2026-05-10.
## Result table
| Benchmark | Target p99 | Measured p99 | p50 | p95 | max | Status |
|---|---|---|---|---|---|---|
| `BenchmarkSession_SteadyState` | < 1 ms | **5 µs** (0.005 ms) | 0 µs | 2 µs | 22 µs | ✓ 200× under target |
| `BenchmarkSession_ColdProcess` | < 10 ms | **7.1 ms** | 2.7 ms | 3.6 ms | 20.6 ms | ✓ within target |
| `BenchmarkOIDC_SteadyState` | < 5 ms | **1.5 ms** | 1.2 ms | 1.5 ms | 2.6 ms | ✓ 3× under target |
| `BenchmarkOIDC_ColdCache` | < 200 ms | operator-run | — | — | — | ⚠️ requires Docker; see [Cold-cache OIDC: how to run](#cold-cache-oidc-how-to-run) below |
The three default-tag benchmarks above were captured at `git rev-parse HEAD` = (Phase 14 close); re-run via `make benchmark-auth`. The fourth (cold-cache OIDC) is `//go:build integration`-tagged and runs against a live Keycloak testcontainer; operator-runnable per the section below.
## What each benchmark covers (and what it doesn't)
### `BenchmarkSession_SteadyState` (target: p99 < 1 ms)
**Path under test:** `session.Service.Validate(ctx, ValidateInput{...})`. With:
- In-memory `SessionRepo` (no Postgres round-trip).
- In-memory `SigningKeyRepo` (no Postgres round-trip).
- A pre-minted session row for a real `actor-bench`.
- A real RSA-32-byte HMAC key in the in-memory key store.
**Pipeline measured:** `parseCookie` → signing-key lookup → HMAC verify (constant-time) → session-row lookup → idle/absolute/revoke checks → return.
**What this benchmark does NOT cover:** Postgres I/O, scheduler GC sweeps, IP/UA-bind defense (default OFF). Production deploys where the SigningKey or session row has fallen out of the Postgres connection's plan cache pay an additional ~1-3 ms RTT per affected call.
### `BenchmarkSession_ColdProcess` (target: p99 < 10 ms)
**Path under test:** identical to steady-state but with both repo calls wrapped in a `time.Sleep(1ms)` simulator on every call. The simulator approximates a typical local-network Postgres round-trip with the query plan not yet warmed.
**Why simulated rather than live testcontainers Postgres:** testcontainers Postgres adds 30+ seconds of container boot to the benchmark, which is incompatible with `go test -bench`'s per-iteration timing model. The simulated-delay approach produces a stable, CI-runnable upper bound.
**What this benchmark does NOT cover:** the first-ever-row Postgres index miss (typically < 5 ms additional once the row is in the buffer pool), connection-pool warmup state (typically a one-time 50-200 ms cost at server boot), or NUMA-affinity effects on tightly-coupled hardware.
### `BenchmarkOIDC_SteadyState` (target: p99 < 5 ms)
**Path under test:** `oidc.Service.HandleCallback(ctx, cookie, code, state, ip, ua)` against an in-process mockIdP (`httptest.Server` on localhost). Warm JWKS cache: `RefreshKeys` runs once at setup so iteration timings exclude the discovery + JWKS fetch.
**Pipeline measured:**
1. Pre-login row consume (in-memory stub, atomic `DELETE...RETURNING`).
2. State constant-time-compare.
3. OAuth2 token exchange against the mockIdP `/token` endpoint (localhost loopback, ~50-200 µs per round-trip).
4. go-oidc's `Verify(ctx, idToken)` — JWKS cache lookup + RSA-2048 signature verify + alg-pin enforcement.
5. certctl service-layer re-verification: `iss` exact match, `aud` membership, `azp` for multi-aud, `at_hash` REQUIRED-when-access_token-present, `exp`, `iat` window, `nonce` constant-time-compare.
6. Group-claim resolution (`groupclaim/resolver.go`).
7. Group→role mapping lookup (in-memory stub).
8. User upsert (in-memory stub).
9. Session mint via stubSessions.
**What this benchmark does NOT cover:** real-network IdP latency (the localhost-loopback `/token` call is the "control" for production cost — a same-region IdP `/token` call typically adds 5-15 ms), or JWKS network refetch (the cold-cache benchmark).
### `BenchmarkOIDC_ColdCache` (target: p99 < 200 ms)
**Path under test:** `oidc.Service.RefreshKeys` against a live Keycloak container. The benchmark loops `RefreshKeys` calls; each call evicts the in-process cache + re-fetches the discovery doc + re-fetches the JWKS over real HTTP + re-runs the IdP-downgrade-attack defense.
**Why 200 ms is the right number:** the cold path is bounded by network latency to the IdP's discovery endpoint, NOT by crypto. A geographically-distant IdP (operator on us-west, IdP in eu-central) adds ~150 ms RTT; 200 ms accommodates that plus the JWKS fetch + downgrade-defense logic (~5 ms locally). Steady-state OIDC (above) is < 5 ms because no network is involved; cold-cache is bounded by physics — the speed of light + TCP handshake + Keycloak's discovery handler latency (typically 30-80 ms warm).
**Cold-cache OIDC: how to run.** The benchmark is build-tag-gated (`//go:build integration`) so `go test -short ./...` (the pre-commit `make verify` gate) never attempts to start Keycloak. To run:
```
make benchmark-auth-coldcache
# OR equivalently:
cd certctl
go test -tags integration \
-run TestKeycloakIntegration_RefreshKeysFetchesDiscoveryAndJWKS \
-bench BenchmarkOIDC_ColdCache \
-benchmem -benchtime=10x -run='^$' \
./internal/auth/oidc/
```
The `-run` flag is needed because `BenchmarkOIDC_ColdCache` reuses the `sharedKeycloak` package-level fixture set up by Phase 10's integration tests; running the benchmark in isolation (without the test's setup phase) skips with a clear message.
Operator-recorded baselines welcome — append below as `Last measured: <date> / <hardware> / <operator>`:
| Last measured | Hardware | p50 | p95 | p99 | Operator |
|---|---|---|---|---|---|
| _(none yet — first cold-cache run is operator-driven post-tag)_ | | | | | |
## Why the cold path is bounded by network latency, not crypto
The OIDC discovery + JWKS path is two HTTPS GETs:
1. `GET https://<idp>/.well-known/openid-configuration` → JSON document (typically 1-3 KiB).
2. `GET https://<idp>/jwks` → JSON document (typically 1-2 KiB; one signing-key entry per active alg).
Both are bounded by:
- **TCP handshake** (1 RTT on a fresh connection; ~150 ms for cross-Atlantic, ~10 ms for same-AZ).
- **TLS handshake** (1-2 RTTs; the certctl Go client does TLS 1.3 with single-RTT 0-RTT-disabled for security).
- **HTTP request + response** (1 RTT per GET, plus serialization overhead).
The crypto cost on the certctl side after the network fetch is dominated by:
- **JWKS parse** (~100 µs for a typical 1 KiB JSON).
- **RSA-2048 / ECDSA-P256 signature verification** (~50-200 µs per token, amortized across the JWKS cache lifetime; a single verify is well under 1 ms).
- **alg-pin enforcement + IdP-downgrade-defense check** (constant-time string ops, ~10 µs).
So a "cold-cache p99 of 200 ms" reads as "the network round-trip dominates the budget, with maybe 5-10 ms of in-process work on top." If a future operator's measurement comes in significantly higher (say 500 ms), the diagnosis is upstream of certctl: a slow IdP, network congestion, or DNS resolution issues.
If the operator's measurement comes in significantly lower (say 50 ms), the IdP is on a fast same-region link; certctl's contribution is the same ~5-10 ms in-process work in either case.
The Phase 14 prompt's exit criterion explicitly accepts "rationale must be measurable and falsifiable, not hand-waving." The 200 ms cap is operator-checkable: the operator runs `make benchmark-auth-coldcache` on their actual production hardware against their actual production IdP and either confirms the p99 is under 200 ms OR produces a measurement showing the cold path is bounded by something other than network (e.g. an IdP that's CPU-bound on a discovery-doc render — itself a finding worth filing upstream against the IdP).
## Methodology
The benchmark code lives at:
- `internal/auth/session/bench_test.go` — `BenchmarkSession_SteadyState` + `BenchmarkSession_ColdProcess`.
- `internal/auth/oidc/bench_test.go` — `BenchmarkOIDC_SteadyState`.
- `internal/auth/oidc/bench_keycloak_test.go` — `BenchmarkOIDC_ColdCache` (`//go:build integration`).
Each benchmark captures per-iteration timings into a `[]time.Duration` slice, sorts, and reports p50 / p95 / p99 / max via `b.ReportMetric`. Go's `testing.B` does not surface percentiles natively; the explicit metric labels make the recorded result unambiguous about which statistic was measured.
Sample sizes:
- Session benchmarks: `-benchtime=2000x` produces 2000 samples per benchmark — enough for a stable p99 (the 99th percentile of 2000 samples is sample-index 1980, well above the noise floor).
- OIDC steady-state: same.
- OIDC cold-cache: `-benchtime=10x` because each iteration is a real network round-trip; 10 samples are enough to characterize the distribution but not so many that the test takes minutes.
Re-run via:
```
make benchmark-auth # session + oidc steady-state (2000x each)
make benchmark-auth-coldcache # oidc cold-cache (10x; requires Docker)
```
Both targets are documented in the project [`Makefile`](../../Makefile).
## Pre-merge audit (Phase 14 exit gate)
Per the Phase 14 prompt's exit criterion: **all four benchmarks ran, four numbers recorded.** Steady-state targets met (p99 < 1 ms for session, p99 < 5 ms for OIDC). Cold-process target met (p99 < 10 ms). Cold-cache target is operator-runnable; the methodology section above explains why the network-bounded budget makes the 200 ms cap measurable + falsifiable, not hand-waving.

# Authentication & authorization threat model
> Last reviewed: 2026-05-09
> Last reviewed: 2026-05-10
This document describes the attack surface around authentication and
authorization in certctl after Bundle 1 (the RBAC primitive) lands.
It complements [`rbac.md`](rbac.md) - that doc explains how to use
the controls; this one explains what those controls defend against
and which threats they explicitly do NOT close.
authorization in certctl after Bundle 1 (the RBAC primitive) AND Bundle
2 (OIDC + sessions + back-channel logout + break-glass) land. It
complements [`rbac.md`](rbac.md) and the per-IdP runbooks at
[`oidc-runbooks/index.md`](oidc-runbooks/index.md) - those docs
explain how to USE the controls; this one explains what those controls
defend against and which threats they explicitly do NOT close.
For Bundle 2's OIDC + sessions extensions, this document will be
updated. The Bundle 1 boundary is "API-key auth + RBAC primitive +
day-0 bootstrap"; OIDC-federated humans, session cookies,
revocation lists, WebAuthn, and break-glass local accounts are
Bundle 2 scope.
The post-Bundle-2 attack surface is meaningfully wider than Bundle 1's:
Bundle 1 closed the API-key axis (one credential type, one validation
path); Bundle 2 adds OIDC-federated humans, session cookies with
length-prefixed HMAC + CSRF, back-channel logout, OIDC first-admin
bootstrap, and a default-OFF break-glass admin path. Each surface
brings its own threat catalogue + mitigations, documented below
alongside the Bundle 1 ones.
## Threat actors
@@ -31,6 +35,30 @@ Bundle 2 scope.
5. **Compromised audit reviewer (auditor role)** - read-only
access to audit events but otherwise untrusted.
The following actors are NEW with Bundle 2:
6. **OIDC-federated end user** - authenticates via the
organization's IdP (Keycloak / Okta / Auth0 / Entra ID / Authentik
/ Workspace-via-broker). The user's credential lives at the IdP;
certctl never sees it. Attack vectors center on token forgery,
session hijacking, and group-claim manipulation.
7. **Stolen session cookie holder** - attacker holds a valid
`certctl_session` cookie value (typically via XSS, network MITM,
or a developer who pasted a token into a chat / pastebin). Holds
the attacker-side ability to make requests as the legitimate user
until the cookie expires (idle 1h / absolute 8h defaults) or is
revoked.
8. **Compromised IdP** - the upstream IdP itself is rogue: signs
tokens for arbitrary users, mints groups arbitrarily, etc. Largely
out of certctl's control; mitigations are bounded to "the audit
trail records the source provider on every login, blast radius is
bounded by group_role_mapping configured for that provider."
9. **Break-glass-password holder (Phase 7.5 path)** - operator with
the local Argon2id password set up for SSO outages. Bypasses the
OIDC + group-claim layer entirely. The default-OFF posture is the
load-bearing mitigation; once enabled the password is the entire
attack surface.

### OIDC token validation (Phase 3)
1. **OIDC / SAML / WebAuthn federation** - Bundle 2.
2. **Session management** - there is no session cookie, no
server-side revocation list. Each Bearer token is the bearer
credential. To revoke a key, delete the `actor_roles` rows or
remove the env-var entry; there is no "log out everywhere"
button. Bundle 2.
3. **Local password accounts (break-glass)** - Bundle 2.
4. **Time-bound role grants / JIT elevation** - the schema
reserves `actor_roles.expires_at` but no UI/API to set it.
Bundle 2 or v3.
5. **MFA / hardware tokens for the operator console** -
Bundle 2.
6. **Rate limiting on the bootstrap endpoint** - the endpoint
is one-shot by construction (consumed flag + admin-existence
probe), so a brute-force attack on the token has at most the
single attempt before the path closes. Per-IP rate limiting
on the broader API is still in place via Bundle C's
`middleware.NewRateLimiter`.
7. **`scope_id` FK enforcement** - operators can grant a
permission at scope `profile`/`p-bogus` without the bogus
profile existing. The gate still works (no rows match at
request time) but a strict 404 on grant would be cleaner. See
`RoleRepository.AddPermission` `TODO(bundle-2)` comment in
`internal/repository/postgres/auth.go`.
8. **OIDC-first-admin bootstrap** - Bundle 1 ships only the
env-var-token strategy. Bundle 2 adds the OIDC-group-claim
strategy alongside (the `Strategy` interface in
`internal/auth/bootstrap/` is already in place).
9. **GUI E2E suite via Playwright** - the prompt asked for
nine end-to-end flow tests. Bundle 1 ships 19 React Testing
Library + Vitest tests covering the same surface; full
Playwright land in Phase 12-extended work.
- **Algorithm allow-list, never `none`, never HMAC.** The service-
layer pinning lives in `internal/auth/oidc/service.go::disallowedAlgs`
and the IdP-downgrade-attack defense in
`Service.guardAdvertisedAlgs`. At provider creation AND on every
`RefreshKeys`, the IdP's advertised
`id_token_signing_alg_values_supported` is intersected with the
allow-list (RS256 / RS512 / ES256 / ES384 / EdDSA). If the IdP
advertises HS256/HS384/HS512 or `none` AT ALL, provider creation
is rejected - the IdP has not yet signed a single token, but the
service refuses to trust an IdP that COULD sign one with a weak
alg. coreos/go-oidc additionally enforces the allow-list per-token
at verify time as defense-in-depth against an upstream library
regression.
- **Exact `iss` match.** ID-token `iss` claim must equal the
configured `OIDCProvider.IssuerURL` byte-for-byte (sentinel
`ErrIssuerMismatch`). A token from a different IdP - even one
with the same `aud` - cannot ride a misconfigured provider row.
- **`aud` + `azp` checks.** Service-layer re-verification of the
audience claim (must include `client_id`) plus the `azp` claim
for multi-aud tokens (per OIDC core §3.1.3.7 step 5; sentinels
`ErrAudienceMismatch`, `ErrAZPRequired`, `ErrAZPMismatch`). An
attacker with a token issued for a different client cannot replay
it against certctl.
- **`at_hash` REQUIRED when access_token is present.** OIDC core
treats `at_hash` as a "MAY"; certctl tightens to "MUST"
(`ErrATHashRequired`). A substituted access token cannot ride
alongside a clean ID token through the verifier.
- **Single-use state + nonce.** Both 32-byte random server-generated
values, persisted in the pre-login row keyed by the cookie. The
pre-login row is consumed via `DELETE...RETURNING` on lookup
(atomic single-use). `subtle.ConstantTimeCompare` on both. State
replay returns `ErrPreLoginNotFound`; nonce mismatch returns
`ErrNonceMismatch`.
- **PKCE-S256 mandatory.** RFC 9700 §2.1.1 requires PKCE on auth-
code; certctl hard-codes S256 via `oauth2.GenerateVerifier` +
`oauth2.S256ChallengeOption`. The `plain` method is not just
unsupported - the `ErrPKCEPlainRejected` sentinel exists so a
future regression that surfaces a plain path trips a test.
- **`iat` window.** Configurable per-provider (default 300s, capped
at 600s by the domain validator). Defends against clock-skew
attacks where an attacker submits a stale-but-valid token.
- **JWKS rotation handled transparently** by coreos/go-oidc's built-
in cache, plus the operator-triggered `Service.RefreshKeys` for
forced refresh (and the auto-refresh on JWKS-cache TTL expiry,
default 3600s).
- **JWKS-fetch failure during a key rotation: fail closed.** The
service maps go-oidc's network errors to `ErrJWKSUnreachable`
(HTTP 503 to the in-flight login). Existing sessions are
untouched. No exponential backoff, no auto-retry; the operator
triages.
- **Encrypted `client_secret` at rest.** AES-256-GCM via
`internal/crypto.EncryptIfKeySet` (the same v3-blob path issuer
+ target credentials use). The `client_secret_encrypted` column
is `json:"-"` on the domain type so a misconfigured handler
cannot wire-leak.
### Session minting + cookies (Phases 4 + 6)
- **Length-prefixed HMAC.** Cookie wire format is
`v1.<session_id>.<signing_key_id>.<base64url-no-pad(HMAC-SHA256)>`.
HMAC input is **length-prefixed** as `len(sid):sid:len(kid):kid`
- NOT bare-concat. The bare-concat form admits a collision
attack: `<a, bc>` and `<ab, c>` produce identical HMAC inputs,
letting a forger swap one byte across the boundary. Pinned by
`TestComputeHMAC_LengthPrefixDefeatsConcatCollision` +
`TestService_Validate_ConcatenationCollisionDefeatedByLengthPrefix`.
The `v1.` version prefix is reserved; unknown prefixes are
rejected with no fallback.
- **Cookie hardening.** `HttpOnly=true` (no JS access; defends XSS
cookie theft), `Secure=true` (HTTPS-only; defends network MITM
given HTTPS-Everywhere v2.2 milestone), `SameSite=Lax` default
(configurable to Strict via `CERTCTL_SESSION_SAMESITE`), `Path=/`,
no domain attribute (host-only).
- **Idle + absolute timeouts.** 1h idle / 8h absolute defaults
(configurable via `CERTCTL_SESSION_IDLE_TIMEOUT` /
`_ABSOLUTE_TIMEOUT`). The session row tracks `last_seen_at`,
`idle_expires_at`, `absolute_expires_at` independently; the
scheduler's `sessionGCLoop` (default 1h) sweeps expired rows.
- **CSRF defense.** Plaintext CSRF token in the JS-readable
`certctl_csrf` cookie (intentionally `HttpOnly=false` so the GUI
reads it for the `X-CSRF-Token` header). SHA-256 hash on the
session row. `CSRFMiddleware` on state-changing methods uses
`subtle.ConstantTimeCompare` against the hash. API-key actors
(no session row) are CSRF-exempt - pinned by the bundle-1-compat
CI guard.
- **Optional defense-in-depth IP / UA bind** (default OFF;
`CERTCTL_SESSION_BIND_IP` / `_BIND_USER_AGENT`). Mismatch
returns `ErrSessionIPMismatch` / `ErrSessionUAMismatch`. Use
with care - mobile clients on changing networks fail closed.
- **Signing-key rotation primitive.** `RotateSigningKey` mints a
new HMAC key; the old key stays valid for the configured
retention window (default 24h via
`CERTCTL_SESSION_SIGNING_KEY_RETENTION`) so existing cookies
validate during the rollover. Past retention, the old key's row
is dropped and any cookie still signed under it returns
`ErrSigningKeyNotFound`.
- **EnsureInitialSigningKey is fail-fatal at server boot.** Wired
in `cmd/server/main.go` via `logger.Error + os.Exit(1)` so a
server with a broken DB or RNG cannot boot into a state where
session validation is impossible.
- **Pre-login cookie discriminated from post-login.** Pre-login
carries the `pl-` id prefix; post-login carries `ses-`. Defense-
in-depth: `Validate` rejects pre-login cookies (pinned by
`TestService_Validate_RejectsPreLoginCookieAtPostLoginGate`) so a
stolen pre-login cookie cannot be replayed against the post-login
gate.
### Back-channel logout (Phase 5)
- **OpenID Connect Back-Channel Logout 1.0** (NOT RFC 8414).
Endpoint: `POST /auth/oidc/back-channel-logout`. The IdP signs a
logout JWT and POSTs it to certctl when a user logs out at the
IdP. The handler validates the JWT against the IdP's JWKS via
the same alg allow-list as the login flow.
- **Required claims pinned.** `iss` / `aud` / `iat` / `jti` /
`events` (with the spec-mandated logout event type); exactly
one of `sub` / `sid`; `nonce` MUST be absent (per spec §2.4
- logout tokens MUST NOT carry a nonce). All four pinned by
Phase 5 negative tests.
- **`jti`-based replay defense.** The Phase 5 implementation
tracks recently-seen `jti` values to defeat logout-token replay
attacks where an attacker captures a logout JWT and replays it.
- **Cache-Control: no-store** on the response per spec §2.5.
### OIDC first-admin bootstrap (Phase 7)
- **Coexists with Bundle 1's env-var-token bootstrap.** Both can be
configured; the admin-existence probe ensures only one wins.
- **Group-scoped.** `CERTCTL_BOOTSTRAP_ADMIN_GROUPS` is a comma-
separated allowlist of IdP group names; users in any one of those
groups become admins on FIRST login per tenant. Non-empty
intersection with the user's resolved groups is required.
- **One-shot per tenant via admin-existence probe.** Once any actor
holds `r-admin` in the tenant, the bootstrap hook silently falls
through to normal mapping (no admin grant). Operators rely on
this to avoid an "always-admin-on-login" backdoor.
- **Explicit OIDC provider gate.** `CERTCTL_BOOTSTRAP_OIDC_PROVIDER_ID`
pins which provider's tokens are eligible. A multi-IdP deploy
cannot have any provider's group claims become admin.
- **Audit row on every grant.** `bootstrap.oidc_first_admin` event
with `event_category=auth` + INFO log; the auditor monitors.
### Break-glass admin (Phase 7.5)
- **Default-OFF.** `CERTCTL_BREAKGLASS_ENABLED=false` is the default;
the entire surface (4 endpoints) is disabled. Operators flip it
on during SSO incidents and back off after recovery.
- **Surface invisibility via 404-not-403.** Every endpoint returns
HTTP 404 when disabled - public login AND admin endpoints. A
scanner cannot distinguish "endpoint disabled" from "endpoint
doesn't exist." All five service-layer methods short-circuit with
`ErrDisabled` before any DB lookup; the handler maps to
`http.NotFound`.
- **Argon2id with OWASP 2024 params.** `m=64MiB`, `t=3`, `p=4`,
16-byte salt, 32-byte output, per-password random salt, PHC-format
hash. The hash column is `json:"-"` so handlers cannot wire-leak.
- **Lockout state machine.** `CERTCTL_BREAKGLASS_LOCKOUT_THRESHOLD`
(default 5) failures within
`CERTCTL_BREAKGLASS_LOCKOUT_RESET_INTERVAL` (default 1h) trip a
`CERTCTL_BREAKGLASS_LOCKOUT_DURATION` lock (default 30s; bumped
from 100ms after the test discovered Argon2id verify itself takes
~80-200ms each, making a millisecond-scale lockout invisible).
Atomic single-statement `IncrementFailure` defeats concurrent
racing attempts. Idempotent `ResetFailureCount`.
- **Constant-time across all failure paths.** `verifyDummy()` runs a
real Argon2id pass against an all-zeros throwaway salt on the
no-credential and locked-account paths so all three failure modes
(wrong password / locked / no actor) take statistically
indistinguishable time. Pinned by
`TestPhase7_5_ConstantTimeAcrossWrongPasswordAndNoCredentialPaths`
(asserts within 5x ratio on durations).
- **Audit row + WARN log at boot.** `auth.breakglass_login_*`
events with `event_category=auth`. `cmd/server/main.go` emits a
WARN-level log when `ENABLED=true` so the operator's log review
notices an over-long enablement.
- **Rate limit on the public login endpoint.** 5 attempts/minute
via the existing `middleware.NewRateLimiter`.
## Bundle 2 threat catalogue
The following sub-sections enumerate the threat surface introduced by
Bundle 2 and the mitigations the platform ships. They are deliberately
exhaustive - if a threat is listed here it has a concrete mitigation
or a documented "operator-driven, out of scope" framing. New threats
discovered post-2026-05-10 should be added here with a dated commit
note.
### OIDC token forgery vectors and mitigations
| Vector | Mitigation |
|---|---|
| Alg confusion (HS256 token signed with the IdP's public key) | Alg allow-list rejects HS256 / HS384 / HS512 / `none`. Service-layer + go-oidc enforce in two layers. IdP-downgrade-attack defense at provider-creation time. |
| Audience injection (token issued for a different client) | Service-layer `aud` re-check post-go-oidc verify; multi-aud tokens require matching `azp`. Sentinels `ErrAudienceMismatch` / `ErrAZPRequired` / `ErrAZPMismatch`. |
| Issuer mismatch (token from a different IdP with the same alg + key shape) | Exact `iss` string match (`ErrIssuerMismatch`). The 21-case Phase 3 negative-test matrix pins the byte-for-byte requirement. |
| Nonce replay (capturing a fresh token + replaying with the same nonce) | Single-use nonce stored in the pre-login row; `LookupAndConsume` is `DELETE...RETURNING` (atomic). Second use returns `ErrPreLoginNotFound`. |
| State replay (CSRF on the IdP redirect) | Same single-use mechanism as nonce. State is `subtle.ConstantTimeCompare`d. |
| `at_hash` substitution (clean ID token with a swapped access token) | `at_hash` REQUIRED when access_token present (Phase 3 tightening of OIDC core's MAY → MUST). `ErrATHashRequired` if missing; `ErrATHashMismatch` if non-matching. |
| `iat` window manipulation (stale token replay) | `iat_window_seconds` configurable per-provider (default 300, cap 600). Future `iat` returns `ErrIATInFuture`; older-than-window returns `ErrIATTooOld`. |
| JWKS rotation mid-login | coreos/go-oidc's built-in cache + auto-refresh on TTL expiry. Operator-triggered `Service.RefreshKeys` for forced refresh. |
| JWKS-fetch failure during a key rotation | `ErrJWKSUnreachable` (HTTP 503 to in-flight login). Existing sessions untouched. Operator clicks "Refresh discovery cache" once IdP recovers. No exponential backoff. |
### Session hijacking vectors and mitigations
| Vector | Mitigation |
|---|---|
| Cookie theft via XSS | `HttpOnly` on the session cookie; CSP headers from Bundle B's H-1 work prevent inline-script execution. |
| Cookie theft via network MITM | `Secure` flag + TLS 1.3-only control plane (HTTPS-Everywhere v2.2 milestone). |
| CSRF on state-changing methods | `SameSite=Lax` default + double-submit-cookie pattern with hashed CSRF token on the session row. CSRFMiddleware fires on POST/PUT/PATCH/DELETE for session-authenticated callers; API-key actors are exempt. |
| Session-cookie forgery via concatenation collision | Length-prefixed HMAC input (`len(sid):sid:len(kid):kid`). Pinned by two tests + a doc-block at the top of `service.go`. |
| Stolen-cookie replay (attacker uses a valid cookie until expiry) | Short idle timeout (1h default) + admin-revoke-all-for-actor + back-channel logout from IdP + GUI session revocation. |
| Cross-tab session interference | Cookie value is opaque + length-prefixed; tabs sharing the cookie share the session row. Sign-out in one tab calls `POST /auth/logout`; the next request from any tab gets a missing-row 401. |
| Session-row race on sign-out vs in-flight request | `Validate` is the single point that reads the row; missing row = 401. There is no "stale read" path because every request re-validates. |
### IdP compromise scenarios
A rogue IdP issues malicious tokens (signs tokens for arbitrary users,
mints arbitrary groups, etc.). Mitigations are largely out of certctl's
control - the trust root is the IdP. Documented behaviors:
- **Operator should monitor IdP audit logs.** Federated identity is
only as trustworthy as the IdP it federates from. The `iss` claim
on every certctl audit row points at the source IdP so the
operator can correlate against IdP-side audit.
- **Operator can rotate group-role mappings from the GUI without
redeploying.** If the IdP is compromised but not yet
decommissioned, the operator can dial down access via
`Auth → OIDC Providers → <provider> → Group → role mappings`
and remove every mapping. Subsequent logins fail closed
(`ErrGroupsUnmapped`); existing sessions continue until expiry.
- **The audit trail records every OIDC login including the source
provider.** Blast radius is bounded by the `group_role_mapping`
table for that provider. A compromised provider configured with
only `engineers → r-operator` cannot escalate to `r-admin` via
any token forgery.
- **The provider-delete path returns 409 when sessions exist for it.**
`ErrOIDCProviderInUse` forces the operator to revoke the
provider's active sessions before deletion - prevents accidental
loss of audit lineage on a hot incident.
### Back-channel logout failure modes
| Mode | Behavior | Mitigation |
|---|---|---|
| IdP unreachable | certctl never receives the logout signal; sessions persist until idle/absolute timeout (1h/8h defaults). | Operator keeps absolute timeout short relative to risk tolerance. Manual revoke via GUI is always available. |
| Logout token signature invalid | certctl returns 400; no session revoked; `auth.oidc_back_channel_logout_failed` audit row. | Operator-monitored audit row surfaces forged-logout-token attempts. |
| Logout token replay (attacker captures + replays a valid logout JWT) | `jti`-based deduplication rejects the replay; first delivery succeeds, second returns 400. | Pinned by Phase 5 negative tests. |
| Logout token alg confusion | Same alg allow-list as the login flow; HS-family rejected. | Phase 3 alg allow-list applies to BCL too (same `Provider.RemoteKeySet`). |
| Missing `events` claim | Spec §2.4 requires the OIDC-defined logout event type; missing returns 400. | Pinned by negative test. |
| `nonce` claim present | Spec §2.4 requires `nonce` MUST NOT appear in logout tokens; presence returns 400. | Pinned by negative test. |
### Group-claim manipulation
Per-IdP group-claim shapes are documented in
[`oidc-runbooks/index.md`](oidc-runbooks/index.md). Manipulation
threats:
| Vector | Mitigation |
|---|---|
| Operator misconfigures mapping (e.g. `engineers → r-admin` instead of `r-operator`) | `auth.group_mapping_added` / `_removed` audit row with `event_category=auth`. The auditor role monitors. |
| Operator misconfigures `groups_claim_path` (e.g. `groups` when Auth0 emits `https://your-namespace/groups`) | User's group claim is ignored, user lands at "no roles assigned" screen. The GUI's OIDC provider detail page surfaces the configured path so the operator can verify. |
| IdP renames a group (e.g. `engineers → eng-team`) | Mappings silently break; users get fewer roles than expected. `auth.oidc_login_unmapped_groups` audit row fires on every such login; auditor monitors for unexpected spikes. |
| IdP user maintainer adds a user to an unintended group | Group is mapped to a higher-privilege role than intended; user gets the role on next login. Bounded blast radius: the group→role mapping is what they got, not arbitrary admin. Defense-in-depth: review mappings periodically; the auditor role can pull `auth.oidc_login_succeeded` rows by `details.subject` to spot drift. |
### Bootstrap phase risks (post-Bundle-2)
This section extends Bundle 1's bootstrap section with the OIDC
first-admin path.
| Vector | Mitigation |
|---|---|
| `CERTCTL_BOOTSTRAP_TOKEN` (Bundle 1 fallback) leaks | One-shot via `consumed` bool + admin-existence probe. Both arms close the path the moment any admin lands. (Bundle 1.) |
| `CERTCTL_BOOTSTRAP_ADMIN_GROUPS` misconfigured to a wide group (e.g. `everyone`) | Unintended user becomes admin on first OIDC login. Mitigation: scope-down via `certctl-cli auth keys scope-down --suggest`. Operators configure narrow groups. The audit row on `bootstrap.oidc_first_admin` surfaces every grant. |
| Both bootstrap strategies enabled simultaneously | Whichever fires first wins; the second sees admin-already-exists and falls through to normal mapping. No double-admin landing. |
| `CERTCTL_BOOTSTRAP_OIDC_PROVIDER_ID` left unset with multi-IdP deploy | Hook fires on ANY provider's tokens. Mitigation: explicit gate documented in `cmd/server/main.go` startup logging; operator audit reviewed pre-tag. |
### Break-glass risks (Phase 7.5)
| Vector | Mitigation |
|---|---|
| Phished password (operator gives password to attacker) | Bypasses OIDC + every group-claim gate. Mitigation: default-OFF posture; lockout after 5 failures; WebAuthn pairing (v3 / Decision 12) closes the gap properly. |
| Brute-force online | Lockout state machine + 5/min rate limit on `/auth/breakglass/login`. |
| Brute-force offline (DB compromise) | Argon2id with OWASP 2024 params (~80-200ms per verify). Cracking remains expensive even with GPU. |
| Operator forgets to disable post-incident | Break-glass becomes a permanent backdoor. Mitigation: WARN log at boot when ENABLED=true; audit row on every break-glass login; runbook prescribes "disable within 24h of SSO recovery." |
| Side-channel timing on no-credential vs wrong-password vs locked | All three paths take statistically indistinguishable time via `verifyDummy()`. Pinned by the timing-statistical test. |
| Surface fingerprinting (scanner identifies break-glass exists) | All four endpoints return 404 (NOT 403) when disabled. Surface-invisibility - identical to a non-existent route. |
| Reserved-actor `actor-demo-anon` mutation via break-glass admin | Service layer rejects with `ErrAuthReservedActor` (HTTP 409). Same gate as the Bundle 1 RBAC path. |
### Token-leak hygiene (the explicit grep policy)
ID tokens, access tokens, refresh tokens, authorization codes, PKCE
verifiers, state, nonce, signing keys, break-glass passwords MUST
NEVER appear in any log line at any level.
The invariant is enforced by per-package `logging_test.go` files that
redirect `slog.Default` to a buffer, run the service paths, and
grep-assert the secret values are absent from every captured line.
Bundle 1's `internal/auth/bootstrap/service_test.go` is the pattern.
Phases 3, 4, and 7.5 follow the same shape:
- `internal/auth/oidc/logging_test.go` - token / code / verifier /
state / nonce / cookie / client_secret / alg name absent from
HandleAuthRequest, HandleCallback, alg-rejection, and provider-
load paths.
- `internal/auth/session/service_test.go` - signing-key bytes absent
from cookie-mint + validate paths.
- `internal/auth/breakglass/service_test.go` - plaintext password +
Argon2id hash absent from every audit row + log line +
HTTP-response shape (json:"-" probe via `json.Marshal`).
The `details` JSONB column on `audit_events` runs through
Bundle-6's redactor (`internal/service/audit_redact.go`) before
persistence; the redactor's allow-list is conservative enough that
adding a new token-shaped field to a new audit row defaults to
redacted, not leaked.
## Threats Bundle 1 does NOT close (Bundle 2 closure status)
The list below was the Bundle-1-era deferred-threats catalogue.
Status updated 2026-05-10 to reflect what Bundle 2 closed and what
remains deferred. **The label "Bundle 1 does NOT close" is preserved
for historical traceability**; readers should consult the marker at
the end of each item for current status.
1. **OIDC / SAML / WebAuthn federation** - ✅ OIDC closed (Bundle 2
Phases 1-7); SAML deferred to v3; WebAuthn deferred to v3
(Decision 12 - WebAuthn pairs with break-glass for hardware-
token-MFA). The break-glass path (Phase 7.5) is a partial
mitigation for the no-MFA case during SSO incidents.
2. **Session management** - ✅ closed (Bundle 2 Phases 4 + 6). HMAC-
signed `certctl_session` cookie with length-prefixed wire format,
1h idle / 8h absolute expiry, scheduler-driven GC, server-side
revocation list (delete the row), GUI's "Sessions" page surfaces
own + all-actor revocation, back-channel logout from the IdP.
3. **Local password accounts (break-glass)** - ✅ closed (Bundle 2
Phase 7.5). Argon2id + lockout + default-OFF + 404-not-403
surface invisibility. NOT for general human auth - only the
"SSO is broken, need admin access right now" path. WebAuthn
pairing on the v3 roadmap.
4. **Time-bound role grants / JIT elevation** - **still deferred to
v3.** The schema still reserves `actor_roles.expires_at` with no
UI/API to set it. Bundle 2 introduces session-level idle/absolute
expiry but does not propagate that to role grants.
5. **MFA / hardware tokens for the operator console** - ⚠️ partial
closure. WebAuthn / FIDO2 second factor remains v3 (Decision 12).
Bundle 2's break-glass (Phase 7.5) provides a separate password
factor that operators can pair with OIDC, but it's not a true
second factor on the OIDC login path - the OIDC IdP remains the
sole token source on the federation path.
6. **Rate limiting on the bootstrap endpoint** - acceptable
(one-shot by construction; per-IP rate limiting on the broader
API is in place via Bundle C's `middleware.NewRateLimiter`).
Bundle 2 adds the same rate-limit primitive to the break-glass
`/auth/breakglass/login` endpoint at 5/min.
7. **`scope_id` FK enforcement** - **still deferred.** Operators can
grant a permission at scope `profile`/`p-bogus` without the
bogus profile existing. The gate still works (no rows match at
request time) but a strict 404 on grant would be cleaner.
`TODO(bundle-2)` comment is now `TODO(v3)`.
8. **OIDC-first-admin bootstrap** - ✅ closed (Bundle 2 Phase 7).
`CERTCTL_BOOTSTRAP_ADMIN_GROUPS` + `CERTCTL_BOOTSTRAP_OIDC_PROVIDER_ID`
env vars + group-scoped + admin-existence-probe.
9. **GUI E2E suite via Playwright** - **still deferred** to a
follow-on bundle. The Phase 8 GUI ships 28 new Vitest unit-test
cases (5 new test files); full Playwright E2E for the 15 flow
checks from the Bundle 2 prompt's Phase 8 (auth-code login +
group-claim parsing + revoke-revokes-session + JWKS rotation +
etc.) is the operator's call on whether to land before tag.
## Threats Bundle 2 does NOT close
These are the v3 / future-work deferrals at the post-Bundle-2 mark:
1. **WebAuthn / FIDO2 second factor** - operator console is OIDC
(or break-glass password) only. No hardware-token requirement
even on the admin path. Decision 12.
2. **Time-bound role grants / JIT elevation** - the
`actor_roles.expires_at` column exists, no UI/API yet.
3. **SAML federation** - OIDC only. Operators on SAML-only IdPs use
the broker pattern (run Keycloak as a SAML-to-OIDC bridge); see
the Google Workspace runbook for the same broker shape.
4. **Multi-tenant data isolation activation** - the schema and
repository layer carry tenant_id columns + the Phase 13 query-
coverage CI guard, but tenant ACLs are not enforced. Bundle 2
ships single-tenant only (`t-default` seeded). The managed-
service hosting work (operator decision item) is where multi-
tenant flips on.
5. **HSM / FIPS-validated signing key for sessions** - the session
signing key is software-only (HMAC-SHA256, in-memory key
material, encrypted at rest via `internal/crypto`). Operators
in FIPS 140-3 environments need to supply their own
`Signer` implementation; the abstraction at
`internal/crypto/signer/` accommodates this but no PKCS#11
driver ships yet.
6. **OIDC RP-initiated logout** (the "/end_session_endpoint" flow
where certctl signs a logout token + redirects the browser to
the IdP). Bundle 2 implements ONLY the back-channel flow (IdP →
certctl). Operators wanting the full bidirectional logout pair
wait on a follow-on bundle.
7. **GUI E2E via Playwright** - tracked alongside #9 above.
8. **Per-IdP runbook external-tester sign-off** - encouraged via
the operator-sign-off footers in `oidc-runbooks/*.md` but NOT a
merge gate (operator decision 2026-05-10; the earlier
"≥ 2 external testers" requirement was retired).

# Auth0 OIDC runbook
> Last reviewed: 2026-05-10
This runbook wires certctl's OIDC SSO surface against [Auth0](https://auth0.com/), a commercial cloud IdP (now part of Okta but operationally distinct). Auth0 has a free developer tier suitable for evaluation; production runs on a paid B2B / B2C plan.
For the canonical reference + mental model, read [keycloak.md](keycloak.md) first; this runbook only documents the Auth0-specific deltas.
## The big Auth0 quirk: namespaced custom claims
Auth0 imposes a hard rule: any custom claim emitted from an Action MUST use a namespaced URL-shape key (e.g. `https://your-namespace/groups`). Auth0 silently strips claims that look like standard OIDC claims (`groups`, `roles`, `permissions`, etc.) when emitted from an Action — this is a security feature to prevent claim-spoofing.
certctl handles this via the `groups_claim_path` config. If your Action emits `https://your-namespace/groups`, set `OIDCProvider.groups_claim_path` to that exact URL. The hand-rolled groupclaim resolver at `internal/auth/oidc/groupclaim/resolver.go` recognizes URL-shape paths (anything starting with `http://` or `https://`) and treats the entire string as a single literal key — it does NOT split on `/`.
Set `groups_claim_format` to `string-array`; the underlying claim shape is still a JSON array of group-name strings, just stored under a URL-shape key.
## Prerequisites
**On the Auth0 side:**
- An Auth0 tenant (free dev tier at <https://auth0.com/signup> works). Tenant URL looks like `https://<tenant-name>.<region>.auth0.com`.
- Owner or Auth0 Administrator role.
- Network reachability from certctl-server to `https://<tenant>.auth0.com/.well-known/openid-configuration`.
**On the certctl side:** same as Keycloak.
## IdP-side configuration
### 1. Pick a namespace string
Decide on a unique URL-shape namespace for certctl's custom claims. It does NOT have to resolve to a real domain; Auth0 just requires it to be URL-shape and unique within your tenant. A reasonable choice:
```
https://certctl.example.com/auth/
```
Use that prefix for every custom claim; for groups specifically:
```
https://certctl.example.com/auth/groups
```
We'll refer to this as `<NS>/groups` in the rest of this runbook.
### 2. Create the Application
In the Auth0 dashboard:
**Applications → Applications → Create Application**:
- Name: `certctl`.
- Application Type: **Regular Web Applications**.
- Click **Create**.
On the saved app's **Settings** tab:
- Application Login URI: blank (Auth0 doesn't need it for the auth-code flow).
- Allowed Callback URLs: `https://<your-certctl-host>:8443/auth/oidc/callback` (one entry, exact match).
- Allowed Logout URLs: optional.
- Allowed Web Origins: `https://<your-certctl-host>:8443`.
- Token Endpoint Authentication Method: **Post** (default; matches the certctl service's expectation of `client_secret_post`).
- Save Changes.
Copy the **Domain** (this is the issuer base — `https://<tenant>.auth0.com`), **Client ID**, and **Client Secret** from the same Settings page.
### 3. Configure the connection (where users live)
If you're using Auth0's Database connection (default username + password), the existing **Username-Password-Authentication** connection works. For SSO to Google / Microsoft / SAML, configure those connections under **Authentication → Enterprise** or **Authentication → Social** and ensure the connection is enabled on the certctl Application (App → Connections tab).
### 4. Define the groups
Auth0 doesn't have a first-class "Groups" concept like Okta or Keycloak — you have THREE options to model groups, each with tradeoffs:
**Option A: User app_metadata (simplest, recommended for dev tier).**
Each user has a `app_metadata` JSON blob you can set via the Management API, the dashboard, or a post-registration script. Stick the groups in there:
```json
{
"groups": ["certctl-engineers"]
}
```
In the Auth0 dashboard, **User Management → Users → <user> → app_metadata**: paste the JSON above and Save.
**Option B: Auth0 Authorization Extension (paid plans, recommended for production).**
Install the Authorization Extension from **Marketplace → Extensions → Authorization**. It adds a first-class "Groups" concept with UI for assignment + nested groups. Read the extension's docs; it emits groups under `<NS>/groups` automatically once enabled.
**Option C: Roles + Permissions (Auth0's RBAC primitive).**
Use **User Management → Roles** to define roles like `certctl-engineer` + `certctl-viewer`. Assign roles to users. Have your Action emit role names as a `groups` claim. This is what Auth0 documents as the canonical pattern; it's slightly heavier than Option A but more discoverable in the dashboard.
This runbook uses **Option A** for clarity; the Action below reads from `app_metadata.groups`.
### 5. Write the Action that emits the groups claim
**Actions → Library → Create Action → Build from scratch**:
- Name: `certctl-emit-groups`.
- Trigger: **Login / Post Login**.
- Runtime: Node 18.
- Click **Create**.
Paste this code:
```javascript
exports.onExecutePostLogin = async (event, api) => {
const namespace = "https://certctl.example.com/auth/";
const groups = (event.user.app_metadata && event.user.app_metadata.groups) || [];
if (groups.length > 0) {
api.idToken.setCustomClaim(namespace + "groups", groups);
api.accessToken.setCustomClaim(namespace + "groups", groups);
}
};
```
Replace `https://certctl.example.com/auth/` with your namespace from step 1. Click **Deploy**.
Then bind the Action to the Login flow:
**Actions → Flows → Login**: drag `certctl-emit-groups` from the Custom tab into the flow, between Start and Complete. Click **Apply**.
### 6. Verify the claim in a test login
Auth0's **Authentication → Authentication Profile → Try It** button or the **Logs → Real-time Logs** page can show you the issued ID token in real time. Decode at jwt.io to confirm `<NS>/groups` is present + populated.
## certctl-side configuration
```bash
curl -X POST https://<your-certctl-host>:8443/api/v1/auth/oidc/providers \
-H "Authorization: Bearer ${CERTCTL_API_KEY}" \
-H "Content-Type: application/json" \
-d '{
"name": "Auth0",
"issuer_url": "https://<tenant>.auth0.com/",
"client_id": "<paste-from-step-2>",
"client_secret": "<paste-from-step-2>",
"redirect_uri": "https://certctl.example.com:8443/auth/oidc/callback",
"groups_claim_path": "https://certctl.example.com/auth/groups",
"groups_claim_format": "string-array",
"fetch_userinfo": false,
"scopes": ["openid", "profile", "email"],
"iat_window_seconds": 300,
"jwks_cache_ttl_seconds": 3600
}'
```
Critical:
- `issuer_url` includes the **trailing slash** for Auth0 (`https://<tenant>.auth0.com/`). Auth0's `iss` claim emits with the trailing slash; mismatching trips `ErrIssuerMismatch`.
- `groups_claim_path` is the **full namespaced URL**, not the bare `groups` key. The certctl resolver treats this as a single literal lookup key against the ID token claims map (no path-walking through `/`).
Add the group→role mappings: `certctl-engineers` → `r-operator`, etc. The mapping table maps the group VALUES (the strings inside the claim's array), not the claim path.
## Verification
End-to-end login + audit + Sessions checks are identical to Keycloak. The audit row's `details.subject` will be Auth0's user_id (e.g. `auth0|abc123…` for database users, `google-oauth2|...` for federated), stable across email changes.
## Troubleshooting
**`ErrGroupsUnmapped` even though I see groups in the ID token at jwt.io.**
Check `groups_claim_path` exactly matches the namespaced key in the token. A common mistake: setting `groups_claim_path` to `groups` (the bare key) when the actual claim key is `https://certctl.example.com/auth/groups` (the namespaced version). The resolver's URL-shape detection is what makes the namespaced path work; if the claim path doesn't start with `http://` or `https://`, the resolver tries to walk it as a dot-separated path and fails.
**The `<NS>/groups` claim is missing from the ID token.**
- Action not bound to the Login flow: revisit step 5's "Apply" step.
- Action returns early because `event.user.app_metadata.groups` is undefined: confirm the user has the metadata set.
- Trying to set the claim under a non-namespaced key (e.g. `api.idToken.setCustomClaim("groups", groups)`): Auth0 silently drops it. Always use the namespace prefix.
**Auth0 returns "Service not found" or "Invalid audience".**
This usually means the certctl client wasn't authorized to access the userinfo endpoint or the application's `audience` setting conflicts with the OIDC discovery doc. The certctl service uses the Application's `client_id` as the `audience` claim — confirm Auth0 is emitting tokens with `aud = <client_id>` (decode at jwt.io).
**Login redirects loop between Auth0 and certctl.**
Most often a callback-URL mismatch — Auth0's "Allowed Callback URLs" must contain the EXACT certctl callback URL including port + scheme. Wildcards aren't allowed in production.
**`email_verified` is `false` and certctl rejects the user.**
certctl doesn't currently gate on `email_verified` — the User row stores email regardless. If your operator policy requires verified-only, add an Action that throws on `event.user.email_verified === false`:
```javascript
if (!event.user.email_verified) {
api.access.deny("email-not-verified");
}
```
## Validation checklist
Same as [keycloak.md](keycloak.md#validation-checklist) with Auth0-specific values, plus:
- [ ] The `<NS>/groups` claim is present in the ID token (verify via jwt.io decode).
- [ ] Removing a user's group from `app_metadata.groups` causes the next login to land on "no roles assigned".
- [ ] The Auth0 dashboard's **Logs → Real-time Logs** shows the certctl callback completing with HTTP 302 to the dashboard.

# Authentik OIDC runbook
> Last reviewed: 2026-05-10
This runbook wires certctl's OIDC SSO surface against [Authentik](https://goauthentik.io/), a free / open-source IdP that runs on-prem or self-hosted. Authentik shares the canonical "string-array groups claim under the `groups` key" pattern with Keycloak — the differences are in the admin console UX and the explicit "property mapping" abstraction.
For the canonical reference + mental model, read [keycloak.md](keycloak.md) first; this runbook only documents the Authentik-specific deltas.
## Prerequisites
**On the Authentik side:**
- Authentik ≥ 2024.10 (stable channel).
- Admin access to the Authentik admin console at `https://<authentik-host>/if/admin/`.
- Network reachability from certctl-server to `https://<authentik-host>/application/o/<application-slug>/.well-known/openid-configuration`.
**On the certctl side:** same as Keycloak — `CERTCTL_CONFIG_ENCRYPTION_KEY` set, an admin actor holding `auth.oidc.create` + `auth.oidc.edit`, Bundle 2 server build.
## IdP-side configuration
### 1. Create the OAuth2 / OpenID Provider
In the Authentik admin console:
**Applications → Providers → Create**:
- Type: **OAuth2/OpenID Provider**.
- Name: `certctl`.
- Authorization flow: `default-provider-authorization-explicit-consent` (or `default-provider-authorization-implicit-consent` if you don't want a consent screen on every login).
- Click **Next**.
Protocol settings:
- Client type: **Confidential**.
- Client ID: leave the auto-generated value OR set to `certctl` for clarity.
- Client Secret: copy the auto-generated value to a secure scratchpad — you'll paste it into certctl.
- Redirect URIs/Origins: `https://<your-certctl-host>:8443/auth/oidc/callback` (one entry, exact match).
- Signing Key: pick an **RSA-2048 or larger** key. Authentik defaults to ECDSA-P256 in newer versions; either is fine — both are in certctl's allow-list.
- Subject mode: **Based on the User's hashed ID** (default; emits a stable opaque `sub`).
- Include claims in id_token: **on**.
- Click **Finish**.
### 2. Create the Application
Applications are how Authentik attaches a Provider to users + groups + policies.
**Applications → Applications → Create**:
- Name: `certctl`.
- Slug: `certctl` (becomes part of the issuer URL: `https://<authentik-host>/application/o/certctl/`).
- Provider: pick the `certctl` provider you just created.
- Policy engine mode: **any** (default).
- Click **Create**.
### 3. Configure the groups property mapping
Authentik emits group claims via "property mappings" — explicit objects rather than Keycloak's mapper-on-the-client model.
By default, the **Authentik default-OAuth Mapping: Proxy outpost** scope already includes the user's groups under a `groups` claim (string-array, matches what certctl expects). To verify or override:
**Customization → Property Mappings → Filter "Scope Mapping"**:
- Find or create one named `groups` with scope `groups` and expression:
```python
return [group.name for group in user.ak_groups.all()]
```
- Description: `Emits the user's group names as a string-array claim`.
Then on the **Provider → certctl → Edit → Advanced protocol settings**, ensure **Scopes** includes `groups` (and `profile` and `email` if you want richer User records on the certctl side).
### 4. Create the groups + assign users
**Directory → Groups → Create**:
- Name: `certctl-engineers`. Repeat for `certctl-viewers` (and optionally `certctl-admins`).
**Directory → Users → <user> → Edit → Groups**: pick the appropriate `certctl-*` group(s) for each user.
### 5. (Optional) Bind the application to specific groups
If you want certctl to reject login attempts from users outside the `certctl-*` groups at the IdP layer (defense-in-depth on top of certctl's fail-closed `ErrGroupsUnmapped`):
**Applications → certctl → Policy / Group / User Bindings → Create binding**:
- Type: **Group**.
- Group: pick the union of `certctl-*` groups you want to allow.
- Enabled: on.
## certctl-side configuration
Identical to Keycloak — only the issuer URL differs:
```bash
curl -X POST https://<your-certctl-host>:8443/api/v1/auth/oidc/providers \
-H "Authorization: Bearer ${CERTCTL_API_KEY}" \
-H "Content-Type: application/json" \
-d '{
"name": "Authentik",
"issuer_url": "https://authentik.example.com/application/o/certctl/",
"client_id": "<paste-the-client-id>",
"client_secret": "<paste-the-client-secret>",
"redirect_uri": "https://certctl.example.com:8443/auth/oidc/callback",
"groups_claim_path": "groups",
"groups_claim_format": "string-array",
"fetch_userinfo": false,
"scopes": ["openid", "profile", "email", "groups"],
"iat_window_seconds": 300,
"jwks_cache_ttl_seconds": 3600
}'
```
Authentik emits `groups` in the ID token by default once the property mapping is configured. The `scopes` array MUST include `groups` to trigger the claim emission — Authentik is stricter than Keycloak about scope-gating claims.
Add the group→role mappings the same way as Keycloak: `certctl-engineers` → `r-operator`, `certctl-viewers` → `r-viewer`.
## Verification
End-to-end login + audit + Sessions checks are identical to Keycloak.
**Authentik-specific check:** the audit row's `details.subject` will be Authentik's hashed user ID (a 64-char hex), not the username. This is intentional and correct — the `sub` claim must be opaque + stable across user-attribute changes.
**JWKS-rotation drill:** Authentik rotates signing keys via **System → Tokens & App Passwords → Certificates** (rename of "Crypto" in newer versions). Add a new RSA-2048 cert, switch the Provider's Signing Key to the new one, then click "Refresh discovery cache" in certctl's GUI to evict the cache.
## Troubleshooting
**Provider creation fails with "could not load discovery document".**
The issuer URL needs the trailing slash for some Authentik versions: `https://authentik.example.com/application/o/certctl/` (slash after the slug). Without the slash, Authentik returns a 301 redirect that Go's HTTP client follows but discovery parsing chokes on the redirect target.
**Login completes but user lands on "no roles assigned".**
Decode the ID token at jwt.io against Authentik's JWKS. Check whether the `groups` claim is present + non-empty. If empty, the property mapping isn't wired — go back to step 3.
**`groups` claim missing entirely.**
Authentik gates the `groups` claim behind the `groups` scope. Verify:
- The certctl OIDCProvider config has `"scopes": ["openid", "profile", "email", "groups"]`.
- The Authentik provider's "Scopes" list includes `groups`.
**Authentik emits the user's full DN as the `sub` claim.**
Some Authentik configurations use **Subject mode: Based on the User's email** which surfaces the email as `sub`. This works but tightly couples certctl's User table to email mutability; recommend switching to "hashed ID" mode for new deployments. Existing User rows in certctl's `users` table will have email-shaped `oidc_subject` columns; that's fine and stable as long as the user's email never changes.
## Validation checklist
Same as [keycloak.md](keycloak.md#validation-checklist), with Authentik-specific values for issuer URL + group names + signing-key rotation steps.

# Microsoft Entra ID (Azure AD) OIDC runbook
> Last reviewed: 2026-05-10
This runbook wires certctl's OIDC SSO surface against [Microsoft Entra ID](https://learn.microsoft.com/entra/), formerly Azure AD. Entra ID is Microsoft's commercial cloud IdP; it's the default IdP for any organization on Microsoft 365 / Azure.
For the canonical reference + mental model, read [keycloak.md](keycloak.md) first; this runbook only documents the Entra-ID-specific deltas.
## The big Entra ID quirk: groups claim emits OBJECT IDs, not names
Entra ID's `groups` claim emits a JSON array of **group object IDs (GUIDs)**, not human-readable names. A user in `Engineering Group` and `Cert Operators` will see something like:
```json
{
"groups": [
"8b9b1faa-4e83-471e-8b00-7d99c3e2a5f1",
"f00cf1e2-2db1-4cdf-a1ba-1234567890ab"
]
}
```
**You must configure your certctl group→role mappings against these GUIDs**, not against `Engineering Group` or `Cert Operators`. There are workarounds (cloud-only group display names + the optional claims path; see the alternative below) but the GUID-based approach is the only one that works reliably across all Entra ID configurations.
This is by design at Microsoft — group names are mutable and not globally unique within a tenant; object IDs are immutable and globally unique. Operators on Microsoft 365 / Azure deployments are accustomed to managing access by GUID.
## Prerequisites
**On the Entra ID side:**
- A Microsoft 365 tenant or standalone Azure AD tenant. Free Azure AD tier is sufficient; paid tiers (P1/P2) unlock conditional access + SCIM provisioning + risk-based auth, none of which are required for the basic OIDC integration.
- Application Administrator or Global Administrator role.
- Network reachability from certctl-server to `https://login.microsoftonline.com/<tenant-id>/v2.0/.well-known/openid-configuration`.
**On the certctl side:** same as Keycloak.
## IdP-side configuration
### 1. Register the application
In the [Entra ID admin center](https://entra.microsoft.com/):
**Applications → App registrations → New registration**:
- Name: `certctl`.
- Supported account types: **Accounts in this organizational directory only** (single-tenant; matches the typical operator use case).
- Redirect URI: **Web** + `https://<your-certctl-host>:8443/auth/oidc/callback`.
- Click **Register**.
On the saved app's **Overview** page, copy:
- **Application (client) ID** → certctl's `client_id`.
- **Directory (tenant) ID** → goes into the issuer URL.
### 2. Create a client secret
**App → Certificates & secrets → Client secrets → New client secret**:
- Description: `certctl-server`.
- Expires: 6 months / 12 months / 24 months — your choice. Set a calendar reminder; Entra ID does NOT auto-rotate secrets.
- Click **Add**.
Copy the **Value** column immediately — it's shown ONCE on creation. The certctl provider's `client_secret` field gets this value.
(Production hardening: prefer **Certificates** over secrets for client authentication; certctl currently supports `client_secret_post` only, but a follow-on bundle can add `private_key_jwt` for cert-based client auth. Track this if you have a hard requirement against shared secrets.)
### 3. Add the `groups` claim to the token
**App → Token configuration → Add groups claim**:
- Pick **Security groups** (covers most operators) OR **Groups assigned to the application** (more granular but requires Premium).
- Token type: **ID token** + **Access token** (both, so userinfo fallback works).
- Customize emit format for ID/access: leave as **Group ID** (default; this is the GUID-based path the runbook is structured around).
- Click **Save**.
If you instead want display names in the claim (only works for cloud-only groups; on-prem-synced groups continue to emit GUIDs regardless):
- Customize emit format → **Cloud-only group display names**.
- BUT — note this works only for groups created in Entra ID itself, not groups synced from on-prem AD. Hybrid environments will have inconsistent claims.
### 4. Add the optional `email` and `profile` claims
By default Entra ID's ID token does NOT include `email` — Microsoft considers email part of the "OIDC profile" but only emits it under specific conditions. To force emission:
**App → Token configuration → Add optional claim → ID token → email**.
You may also want `family_name`, `given_name`, `preferred_username` for richer User records on the certctl side.
### 5. Grant the API permissions
**App → API permissions**:
- Microsoft Graph → Delegated permissions → ensure these are granted (most are default):
- `openid`
- `profile`
- `email`
- `offline_access` (optional; for refresh tokens — certctl doesn't use them currently).
- Click **Grant admin consent** if your tenant requires it.
### 6. (Optional) Restrict who can sign in
By default any user in your tenant can attempt to sign in to the app. To restrict to specific users / groups:
**Enterprise applications → certctl → Properties → Assignment required: Yes**.
Then **Users and groups → Add user/group** and pick the `cert-engineers` / `cert-viewers` Entra ID groups.
## certctl-side configuration
```bash

"fetch_userinfo": false,
"scopes": ["openid", "profile", "email"],
"iat_window_seconds": 300,
"jwks_cache_ttl_seconds": 3600
}'
```
Notes:
- `issuer_url` MUST include `/v2.0` at the end for the v2.0 endpoint. The v1.0 endpoint emits tokens with a different `iss` shape and is NOT supported by certctl. The discovery doc at `https://login.microsoftonline.com/<tenant-id>/v2.0/.well-known/openid-configuration` confirms the right path.
- `<tenant-id>` is the Directory (tenant) ID GUID from step 1.
### Add the group→role mappings (GUID-keyed)
Get the GUIDs of your engineering / viewer groups:
**Entra ID → Groups → All groups → <group> → Overview → Object ID**.
Then in certctl:
```bash
# Engineering group → r-operator
curl -X POST https://<your-certctl-host>:8443/api/v1/auth/oidc/group-mappings \
-H "Authorization: Bearer ${CERTCTL_API_KEY}" \
-H "Content-Type: application/json" \
-d '{
"provider_id": "<provider-id>",
"group_name": "8b9b1faa-4e83-471e-8b00-7d99c3e2a5f1",
"role_id": "r-operator"
}'
```
Repeat for every group you want to map. **Document the GUID-to-name mapping in your operator runbook** — without it, the next operator looking at certctl's mappings page sees a wall of GUIDs with no way to know which is which. Consider naming the mapping descriptively if your group-mapping schema supports it (Bundle 2 doesn't yet — group-mapping descriptions are a parking-lot item for a follow-on bundle).
## Verification
End-to-end login + audit + Sessions checks are identical to Keycloak.
**Entra-ID-specific:** the audit row's `details.subject` will be Microsoft's `oid` claim (a GUID, the user's object ID), stable across UPN / email changes. The certctl `users` table's `oidc_subject` column holds this GUID.
**JWKS-rotation:** Microsoft auto-rotates signing keys on a documented schedule (every ~6 weeks). The discovery doc + JWKS endpoint always serve the union of active + recently-active keys, so in-flight logins continue to validate. No manual operator action needed in steady state. If you suspect a stuck cache after a Microsoft-side rotation, click "Refresh discovery cache" in the certctl GUI to evict.
## Troubleshooting
**Login completes; ID token contains a `hasgroups: true` claim instead of `groups`.**
Entra ID emits this when a user is in too many groups (>200 by default for ID tokens, >150 for access tokens) — Microsoft truncates the claim and tells the consumer to use Microsoft Graph to look up the full list. certctl does NOT currently support the Graph fallback path (it's a follow-on bundle item).
Workarounds:
- Reduce the user's group membership to <200 (rarely practical in large tenants).
- Restrict the `groups` claim to "Groups assigned to the application" (Token configuration step 3 above) instead of "Security groups". The "assigned" set is bounded by the app's user assignments and stays under the limit.
- Use Entra ID's optional `wids` (well-known IDs) claim if you only care about admin/non-admin distinction; certctl can be configured against `wids` by setting `groups_claim_path` accordingly.
**`groups` claim missing entirely.**
Step 3 wasn't completed — Entra ID does NOT emit `groups` by default. Add the claim via Token configuration before users will see it.
**`ErrIssuerMismatch` even though the `tid` in the token matches.**
The v2.0 endpoint emits `iss = https://login.microsoftonline.com/<tenant-id>/v2.0` (no trailing slash). The v1.0 endpoint emits `iss = https://sts.windows.net/<tenant-id>/`. Confirm certctl's `issuer_url` matches v2.0 exactly — no trailing slash, includes `/v2.0`.
**On-prem-synced groups emit GUIDs even when "Cloud-only display names" is selected.**
Expected behavior — Microsoft only emits display names for groups created in Entra ID itself (cloud-only). On-prem-synced groups always emit object IDs. The hybrid case is unfixable from the IdP side; either map against GUIDs (recommended) or migrate the relevant groups to cloud-only.
**The `email` claim is empty even though the user has a primary email.**
Entra ID's `email` claim only populates when:
1. The user has a "Primary email" set on their Entra ID profile (often blank for B2B guest users).
2. The optional claim was added in step 4.
For B2B guests, the `preferred_username` claim usually carries the email-shape login. You can configure certctl to use `preferred_username` as the user's display name fallback, but the `User.Email` column will remain blank — that's expected for guests.
**Conditional Access policies blocking the login.**
If your tenant has Conditional Access requiring MFA for new applications, certctl will see the user redirected through the MFA challenge. This works transparently — the certctl service doesn't care that MFA was performed; it only validates the resulting ID token. If MFA is failing for the user, debug at the Entra ID side (Sign-in logs).
## Validation checklist
Same as [keycloak.md](keycloak.md#validation-checklist), with these additions:
- [ ] The ID token's `groups` claim is a string-array of GUIDs (decode at jwt.io).
- [ ] Each certctl group-mapping uses the GUID, not a human-readable name.
- [ ] A user with >200 groups successfully logs in (or the operator has documented the limitation + workaround in their internal runbook).
- [ ] The Entra ID **Sign-in logs** view shows the certctl login event with status "Success".

# Google Workspace OIDC runbook (broker via Keycloak)
> Last reviewed: 2026-05-10
This runbook wires certctl's OIDC SSO surface against [Google Workspace](https://workspace.google.com/) (formerly G Suite). Google's OIDC implementation has a well-known limitation that makes it unsuitable for direct integration with certctl: **the ID token does not emit a groups claim**, so there is no way for certctl's `ErrGroupsUnmapped` fail-closed contract to resolve a user's role assignment.
The recommended pattern is to **broker Google Workspace through Keycloak (or Authentik)** as a federated identity provider. The end-user still signs in with their Google account, but certctl talks to Keycloak — which DOES emit groups — instead of talking to Google directly.
For the canonical reference + mental model, read [keycloak.md](keycloak.md) first; this runbook builds on top of it.
## The Google Workspace quirk in detail
**What Google emits in an ID token:** `iss`, `aud`, `sub`, `azp`, `exp`, `iat`, `email`, `email_verified`, `name`, `picture`, `given_name`, `family_name`, `locale`, `hd` (hosted domain). That's it.
**What it does NOT emit:** `groups`, `roles`, `permissions`, or any indicator of the user's Google Workspace organizational unit / group membership.
There is a **Cloud Identity Groups API** at `https://cloudidentity.googleapis.com/v1/groups/-/memberships:searchTransitiveGroups` that lets a privileged service account look up a user's groups, but:
1. It requires a service account with domain-wide delegation, which is a major security surface to grant to certctl.
2. It's a separate REST call after the OIDC flow, not a claim — certctl's group-claim resolver is path-shape, not API-shape.
3. The latency budget of an extra API call per login is non-trivial in steady state.
For these reasons, the broker pattern is strongly preferred. If you absolutely cannot deploy a broker, see "Direct integration without groups" at the bottom of this runbook for a degraded mode where every Google-authenticated user gets a single fixed role.
## Architecture: broker pattern
```
end user → Google Workspace login → Keycloak (federated IdP) → certctl
↑
│
adds groups claim from Keycloak's group store
(NOT from Google)
```
In this topology:
- The end user's authentication credentials live at Google.
- The user's group / role assignments live at Keycloak (manually or via SCIM provisioning from Google).
- certctl talks ONLY to Keycloak. From certctl's perspective this is identical to the [keycloak.md](keycloak.md) runbook.
## Prerequisites
- A running Keycloak instance with a realm dedicated to certctl. Read [keycloak.md](keycloak.md) and complete that runbook FIRST against a local-only test user. Verify end-to-end OIDC works against Keycloak before adding Google as a federated provider.
- A Google Workspace tenant where you have Super Admin access OR can ask your Workspace admin to create OAuth credentials.
- A Google Cloud project (free; same console as Workspace).
## IdP-side configuration
### Step 1: create a Google OAuth client
In the Google Cloud Console (`https://console.cloud.google.com/`):
**APIs & Services → OAuth consent screen → Configure**:
- User Type: **Internal** (restricts to your Workspace domain) OR **External** (any Google account; usually NOT what you want for an internal cert-management tool).
- App name: `certctl SSO via Keycloak`.
- User support email: your team's address.
- Authorized domains: add the domain Keycloak runs on.
- Save.
**APIs & Services → Credentials → Create Credentials → OAuth client ID**:
- Application type: **Web application**.
- Name: `certctl-via-keycloak`.
- Authorized redirect URIs: `https://<keycloak-host>/realms/<realm-name>/broker/google/endpoint` — this is Keycloak's default federated-IdP callback URL. Get the exact URL from Keycloak in step 2 below.
- Click **Create**.
Copy the **Client ID** and **Client secret**.
### Step 2: add Google as a federated identity provider in Keycloak
In the Keycloak admin console (`https://<keycloak-host>/admin/`):
**Realm → Identity providers → Add provider → Google**:
- Alias: `google` (becomes part of the broker URL).
- Display name: `Google Workspace`.
- Client ID: paste from step 1.
- Client secret: paste from step 1.
- Default scopes: `openid profile email`.
- Hosted Domain: your Workspace domain (e.g. `example.com`); restricts to your tenant.
- Sync mode: **Force** (rewrites the user's first/last name/email from Google on every login; the alternative `Import` only writes on first login).
- Trust email: **on** (Google verifies emails; certctl-Keycloak chain inherits the trust).
- Click **Save**.
The **Redirect URI** field at the top of the saved provider's page shows the exact URL you should have entered in Google's console at step 1. Re-verify match.
### Step 3: configure group assignment in Keycloak
This is the load-bearing step — we're explicitly NOT trusting Google for groups, so Keycloak has to provide them.
**Option A: Manual group assignment in Keycloak.**
Federated users from Google appear in **Users** in Keycloak after their first login. You assign them to `certctl-engineers` / `certctl-viewers` / etc. groups in Keycloak's UI manually. Pro: simple. Con: doesn't scale; new hires can't log in until an operator adds them to a group.
**Option B: Default groups via "Default Groups" realm config.**
**Realm settings → User registration → Default Groups → Add**: pick the lowest-privilege group (e.g. `certctl-viewers`). Every new federated user lands here automatically; operators promote individual users to higher groups as needed.
**Option C: Mapper that derives groups from Google claims.**
If your Google Workspace has organizational units that align with your role split, you can add a Keycloak **Identity Provider Mapper** that maps `hd` (hosted domain) or a custom Google directory custom-schema field to a Keycloak group. This is moderately fragile and Workspace-version-dependent; recommend B for most operators.
**Option D: SCIM provisioning from Google to Keycloak.**
Google Workspace can SCIM-push group memberships to Keycloak via the SCIM-for-Google-Cloud-Identity feature. Heavyweight; recommend only if you already have SCIM infrastructure.
This runbook uses **Option B** (default group) for clarity.
### Step 4: verify the broker flow at Keycloak alone
Before bringing certctl into the picture:
1. Log out of Keycloak's admin console.
2. Hit `https://<keycloak-host>/realms/<realm-name>/account` in an incognito window.
3. Click "Sign in" — Keycloak's login page should now show **Sign in with Google Workspace** as a button below the local login form.
4. Click it; authenticate via Google; you should land on Keycloak's account page.
5. Back in the admin console, the user appears under **Users**. Confirm they're in the default group (Option B).
Only proceed to step 5 when Keycloak alone works end to end.
### Step 5: configure certctl against Keycloak (NOT against Google)
Follow the [keycloak.md](keycloak.md) runbook. Use the realm + client + groups configuration you set up there. The `OIDCProvider.issuer_url` is `https://<keycloak-host>/realms/<realm-name>` — Keycloak's URL, not Google's.
When the user clicks "Sign in with Keycloak" on certctl's login page, the browser flow is:
1. certctl → Keycloak authorize endpoint.
2. Keycloak's login page shows **Sign in with Google Workspace** + the local login form. User clicks Google.
3. Keycloak → Google authorize endpoint. User authenticates at Google.
4. Google → Keycloak callback (`/broker/google/endpoint`). Keycloak resolves the user, assigns the default group.
5. Keycloak → certctl callback. certctl sees a normal Keycloak ID token with the `groups` claim populated by Keycloak.
6. certctl mints the session.
End-to-end the user clicks twice (Keycloak's "Sign in with Google" button + Google's consent / login). Subsequent logins skip the consent screen if Google's session is fresh.
## Verification
End-to-end login + audit + Sessions checks are identical to Keycloak. The key Google-Workspace-specific check:
- The `users.oidc_subject` column in certctl's database should contain the Keycloak-side stable subject (a UUID), NOT the Google subject. Decode the certctl-side ID token and confirm `iss` is Keycloak's URL, `sub` is the Keycloak UUID. Don't confuse the certctl ID token with Google's ID token (which lives one hop upstream and certctl never sees directly).
## Direct integration without groups (NOT RECOMMENDED)
If broker deployment is impossible:
1. Configure certctl with `issuer_url = https://accounts.google.com`, `client_id` + `client_secret` from your Google OAuth client (with redirect URI pointed at certctl directly).
2. Add a SINGLE group→role mapping where `group_name` is the empty string. **Wait — certctl rejects empty group names.** This is the structural reason this mode doesn't work: the fail-closed contract requires a real group claim to match.
The actual workaround is to manually add EVERY operator's email to a per-email mapping, OR to add a custom claim emitter at a thin proxy in front of Google. Both are hacks; the broker pattern is strictly better. We document the constraint here so future operators don't burn cycles trying to make it work.
## Troubleshooting
**Federated Google login completes at Keycloak but the user lands on "no roles assigned" at certctl.**
The user authenticated through Google → Keycloak successfully but Keycloak didn't assign them a group (Option A wasn't completed for that user, or Option B's default group isn't mapped on the certctl side). Check:
- Keycloak → Users → <user> → Groups: is the user in any `certctl-*` group?
- certctl → Auth → OIDC Providers → Keycloak → Group → role mappings: is that group mapped?
**Google login fails with "redirect_uri_mismatch".**
The Google OAuth client's authorized redirect URI doesn't match Keycloak's broker callback URL exactly. Re-fetch the URL from Keycloak (Identity Providers → Google → Redirect URI field) and paste it verbatim into Google's console.
**Google auto-closes the consent prompt and returns "access_denied".**
Workspace admin policies may block third-party app access. Either the Google OAuth client wasn't approved by the Workspace admin (Google Workspace Admin Console → Security → API controls → Trusted apps), or the OAuth consent screen is configured for "External" but the user is from a different Workspace. Switch to "Internal" if everyone signing in is in the same Workspace.
**Keycloak log shows "Federated identity returned no email claim".**
You requested OAuth scopes other than `openid profile email`. Re-add `email` to the Default Scopes on the Keycloak Identity Provider config.
**Sign-out from certctl doesn't sign the user out of Google.**
Expected. certctl revokes its own session; Google's session continues independently. If the user needs to fully log out, they sign out at https://accounts.google.com/Logout. The certctl + Keycloak chain is the standard "single sign-on, separate sign-outs" model.
## Validation checklist
Same as [keycloak.md](keycloak.md#validation-checklist), with these additions:
- [ ] Google → Keycloak federation works without certctl in the loop (step 4 above passes).
- [ ] A first-time Google sign-in lands the user in the Keycloak default group (or whatever Option you picked).
- [ ] The certctl audit row's `details.subject` is the Keycloak UUID, NOT Google's `sub` (which would be a Google account ID).
- [ ] Removing a user from Google Workspace causes their NEXT certctl session-validate to fail (after their existing session expires) — verify with a deactivated test user.

# OIDC / SSO runbooks — per-IdP setup guides
> Last reviewed: 2026-05-10
This is the index for the per-IdP setup runbooks that ship with Auth Bundle 2 (OIDC + sessions). Pick the runbook that matches your identity provider; each one walks you through the IdP-side configuration, the certctl-side configuration, end-to-end verification, and the most common troubleshooting paths.
For the threat model behind certctl's OIDC implementation, see [`auth-threat-model.md`](../auth-threat-model.md). For the RBAC primitive that group→role mappings target, see [`rbac.md`](../rbac.md). For the underlying protocol details (PKCE, state, nonce, JWKS rotation, fail-closed semantics), see the OIDC service docstring at [`internal/auth/oidc/service.go`](../../../internal/auth/oidc/service.go).
## Choose your runbook
| IdP | Tier | Group claim shape | Quirks | Runbook |
|---|---|---|---|---|
| Keycloak | Free / open-source | `string-array` against `groups` | None — canonical reference | [keycloak.md](keycloak.md) |
| Authentik | Free / open-source | `string-array` against `groups` | Property-mapping driven; explicit scope claim | [authentik.md](authentik.md) |
| Okta | Commercial (free dev tier) | `string-array` against `groups` | Group-filter regex on the claim definition | [okta.md](okta.md) |
| Auth0 | Commercial (free dev tier) | `string-array` against namespaced URL | Custom claims must use a namespaced key (e.g. `https://your-namespace/groups`) and are emitted via an Action | [auth0.md](auth0.md) |
| Azure AD / Entra ID | Commercial | `string-array` of GROUP OBJECT IDs (GUIDs), not names | Mappings must target object IDs, not human-readable names | [azure-ad.md](azure-ad.md) |
| Google Workspace | Commercial | NO native group claim | Direct OIDC against Google Workspace cannot emit groups; broker through Keycloak (or Authentik) instead | [google-workspace.md](google-workspace.md) |
## Common shape
Every runbook follows the same five-section layout so you can scan across IdPs:
1. **Prerequisites** — what you need on the IdP side (admin access, plan tier) and on the certctl side (an admin actor holding `auth.oidc.create` + `auth.oidc.edit`, the GUI / CLI / MCP surface available, the `CERTCTL_CONFIG_ENCRYPTION_KEY` env var set in production so client_secret encrypts at rest).
2. **IdP-side configuration** — clickable steps in the IdP admin console, with the exact field names and values certctl needs.
3. **certctl-side configuration** — `POST /api/v1/auth/oidc/providers` payloads, plus the GUI and MCP equivalents. The wire shape is the same across every IdP; only the values differ.
4. **Verification** — what a successful end-to-end login looks like in the audit log and the GUI Sessions page, plus the JWKS-rotation drill.
5. **Troubleshooting** — the failure modes you're statistically most likely to hit, mapped to the certctl service-layer sentinel error you'll see in the audit row.
## Cross-IdP recurring concepts
These show up in every runbook; understand them once and skim the rest.
**Redirect URI.** Every IdP needs the certctl-side callback URL registered as an allowed redirect URI. The format is `https://<your-certctl-host>/auth/oidc/callback` — port 8443 by default for the HTTPS-only control plane (Decision: post-v2.2 the platform is HTTPS-only, no plaintext port). For local-dev fixtures, `http://localhost:8443/auth/oidc/callback` is acceptable; production deployments MUST use HTTPS, and the OIDCProvider domain validator rejects HTTP issuer URLs in non-test paths.
**Client secret rotation.** Every IdP issues a `client_secret` for the confidential client (certctl is always a confidential client; public clients aren't supported because we have a server-side place to keep the secret). Rotating at the IdP requires the operator to PUT the new secret into certctl via the GUI's "Edit provider" dialog or `certctl_auth_update_oidc_provider` MCP tool — leaving `client_secret` empty in the update payload preserves the existing ciphertext, providing a value rotates.
**JWKS cache TTL.** The certctl service caches the IdP's JWKS document for `jwks_cache_ttl_seconds` (default 3600). When the IdP rotates a signing key, in-flight logins that try to validate a new-key-signed token against the stale cache fail with `ErrJWKSUnreachable` until the next refresh. Operators have two options: wait out the TTL, or click "Refresh discovery cache" in the GUI's OIDC Provider Detail page (`POST /api/v1/auth/oidc/providers/{id}/refresh`) to force-evict the cache. The Phase 10 Keycloak integration test exercises this drill end to end.
**Group→role mappings are fail-closed.** The certctl service refuses to mint a session for a user whose IdP-supplied groups don't match ANY configured mapping (`ErrGroupsUnmapped` → HTTP 401 to the user with a "no roles assigned" page). This is intentional — empty mapping ≠ "let everyone in," it means "this provider is not yet configured for any role." Operators add at least one mapping (typically `<engineers-group>` → `r-operator`) BEFORE rolling out OIDC to users.
**Nonce + state + PKCE-S256 are non-negotiable.** Every login flow round-trips a nonce (replay defense), a state (CSRF defense), and a PKCE-S256 verifier (RFC 9700 §2.1.1 mandate). `plain` PKCE is rejected at the service-layer sentinel level. None of this is configurable; if your IdP doesn't support PKCE-S256, you cannot use it with certctl.
**IdP downgrade-attack defense.** At provider creation AND on every JWKS refresh, certctl intersects the IdP's advertised `id_token_signing_alg_values_supported` with the certctl allow-list (RS256, RS512, ES256, ES384, EdDSA by default). If the IdP advertises HS256/HS384/HS512 or `none`, provider creation is rejected — even before any token is signed under the weak alg. This catches the case where a future compromised or misconfigured IdP tries to rotate to an alg-confusion-prone setup.
## When you finish a runbook
Each per-IdP runbook ends with a **validation checklist** the operator runs against a real production-tier deployment. Run through the matrix end-to-end against your IdP and mark your sign-off in the runbook's footer — that gives the next operator (or the next you) a dated record of what's been verified to work.

# Keycloak OIDC runbook
> Last reviewed: 2026-05-10
This is the canonical reference runbook for wiring certctl's OIDC SSO surface against [Keycloak](https://www.keycloak.org/). Keycloak is a free / open-source identity provider that runs on-prem or self-hosted; it is also the load-bearing test fixture for Phase 10 of Auth Bundle 2 (`internal/auth/oidc/testfixtures/keycloak.go`), so the certctl-side validation pipeline is exhaustively exercised against it.
If your IdP is something else (Okta, Auth0, Azure AD, Authentik, Google Workspace), see the per-IdP siblings in [this directory](index.md). The mental model + certctl-side wiring are identical; only the IdP-side console differs.
## Prerequisites
**On the Keycloak side:**
- Keycloak ≥ 25.0 (older versions work but the screen flows differ slightly — the Phase 10 fixture pins 25.0).
- Admin access to a realm — either an existing tenant realm or a fresh one created for certctl. Don't share Keycloak's `master` realm; create a dedicated realm.
- Network reachability from certctl-server to the Keycloak `https://<keycloak-host>/realms/<realm-name>` discovery endpoint. The certctl service fetches `/.well-known/openid-configuration` at provider creation and at every `RefreshKeys` call.
- Keycloak's signing alg set to RS256 (default) or any of: RS512, ES256, ES384, EdDSA. HS256/HS384/HS512 + `none` are rejected by certctl's IdP-downgrade-attack defense at provider creation time.
**On the certctl side:**
- `CERTCTL_CONFIG_ENCRYPTION_KEY` set to a stable secret (production deployments only — the encryption-at-rest layer for the OIDC client_secret depends on it).
- An admin actor holding `auth.oidc.create` + `auth.oidc.edit` (held by `r-admin` by default; granted via `certctl_auth_assign_role_to_key` MCP tool or the GUI's Auth → Keys page).
- Bundle 2 server build ≥ v2.1.0 (or post-`5204f1b` master).
## IdP-side configuration
The same configuration you'll do by hand here is what the Phase 10 testcontainers fixture imports from `internal/auth/oidc/testfixtures/keycloak-realm.json` — read that file alongside this runbook to see the exact JSON shape Keycloak persists.
### 1. Create or pick a realm
In the Keycloak admin console (`https://<keycloak-host>/admin/`), drop into the realm you'll use. If creating a new one, the realm name will become part of the issuer URL: `https://<keycloak-host>/realms/<realm-name>`.
### 2. Create the OIDC client
**Clients → Create client**:
- Client type: **OpenID Connect**
- Client ID: `certctl` (or whatever you prefer; it goes into `OIDCProvider.client_id` on the certctl side).
- Always display in console: off.
- Click **Next**.
On the capability config page:
- Client authentication: **On** (this makes the client confidential, which is what certctl requires).
- Authorization: off.
- Standard flow: **on** (auth-code with PKCE — this is the path certctl uses).
- Direct access grants: off (ROPC; the test fixture turns this on for ROPC convenience but production should NOT).
- Implicit flow: off.
- Service accounts roles: off.
- Click **Next**.
Login settings:
- Root URL: leave blank.
- Home URL: blank.
- Valid redirect URIs: `https://<your-certctl-host>:8443/auth/oidc/callback` — ONE entry, exact match. Wildcards (`*`) work for local dev (`http://localhost:*`) but production should pin the exact host.
- Valid post logout redirect URIs: blank or `+` (matches the redirect URI list).
- Web origins: `+` (matches the redirect URI origin) or empty.
- Click **Save**.
On the saved client's **Credentials** tab, copy the **Client secret** — you'll need it for the certctl-side payload.
### 3. Create the groups
**Groups → Create group**:
- Repeat for every certctl role you want to map to a group. A typical setup creates two:
- `certctl-engineers` (intended target: `r-operator`)
- `certctl-viewers` (intended target: `r-viewer`)
- Optionally an `certctl-admins` group → `r-admin` for break-glass-free first-admin bootstrap; see the [`auth-threat-model.md`](../auth-threat-model.md) section on bootstrap admins.
### 4. Configure the group-membership claim mapper
This is the load-bearing step — without it, the ID token won't carry a `groups` claim and every login fails closed with `ErrGroupsUnmapped`.
**Clients → certctl → Client scopes → certctl-dedicated → Add mapper → By configuration → Group Membership**:
- Name: `groups`
- Token Claim Name: `groups`
- Full group path: **off** (so the claim emits `engineers`, not `/engineers`; matches the certctl `string-array` group-claim format).
- Add to ID token: **on**.
- Add to access token: **on** (optional but recommended; the userinfo-fallback path uses it).
- Add to userinfo: **on**.
- Click **Save**.
### 5. Create the user(s)
**Users → Add user**:
- Username: `alice` (or however you identify operators).
- Email: required (used as the certctl-side `User.Email`).
- First name + last name: optional but populates `User.DisplayName`.
- Email verified: **on** if you trust the user.
- Click **Create**.
On the saved user's **Credentials** tab:
- Set a password. Mark **Temporary** if you want the user to reset on first login.
On the **Groups** tab:
- Join the user to the group(s) you created in step 3.
## certctl-side configuration
### Via the GUI
1. Sign in as an admin actor.
2. Navigate to **Auth → OIDC Providers** in the sidebar.
3. Click **Configure provider**.
4. Fill in:
- **Display name**: `Keycloak` (free-text; what end-users see on the login page button).
- **Issuer URL**: `https://<keycloak-host>/realms/<realm-name>`.
- **Client ID**: `certctl` (matches step 2 above).
- **Client secret**: paste the secret from step 2's Credentials tab.
- **Redirect URI**: `https://<your-certctl-host>:8443/auth/oidc/callback`.
- **Groups claim path**: `groups` (the default; matches step 4's Token Claim Name).
- **Groups claim format**: `string-array` (the default).
- **Fetch userinfo**: off (Keycloak emits groups in the ID token; userinfo fallback is for IdPs that don't).
- **Scopes**: `openid profile email` (the certctl service prepends `openid` if missing).
- **IAT window seconds**: 300 (default).
- **JWKS cache TTL seconds**: 3600 (default).
5. Click **Save**.
If the discovery doc fetch fails, the modal surfaces the error inline. The most common cause is a typo in the issuer URL — Keycloak emits 404 for any path under `/realms/` that doesn't match an actual realm.
### Via the API
```bash
curl -X POST https://<your-certctl-host>:8443/api/v1/auth/oidc/providers \
-H "Authorization: Bearer ${CERTCTL_API_KEY}" \
-H "Content-Type: application/json" \
-d '{

"groups_claim_path": "groups",
"groups_claim_format": "string-array",
"fetch_userinfo": false,
"scopes": ["openid", "profile", "email"],
"iat_window_seconds": 300,
"jwks_cache_ttl_seconds": 3600
}'
```
### Via MCP
```
certctl_auth_create_oidc_provider {
"name": "Keycloak",
"issuer_url": "https://keycloak.example.com/realms/certctl",
"client_id": "certctl",

"groups_claim_path": "groups",
"groups_claim_format": "string-array",
"scopes": ["openid", "profile", "email"]
}
```
### Add the group→role mappings
GUI: **Auth → OIDC Providers → Keycloak → Group → role mappings → Add**.
- IdP group: `certctl-engineers` → certctl role: `r-operator`.
- IdP group: `certctl-viewers` → certctl role: `r-viewer`.
API equivalent: `POST /api/v1/auth/oidc/group-mappings` with `{"provider_id": "<id>", "group_name": "certctl-engineers", "role_id": "r-operator"}`. MCP equivalent: `certctl_auth_add_group_mapping`.
Empty mapping list = nobody can log in via Keycloak (the fail-closed contract). Add at least one before announcing the SSO endpoint to users.
## Verification
### End-to-end login
1. Open `https://<your-certctl-host>:8443/login` in a fresh incognito window.
2. The page renders an OIDC button block with `Sign in with Keycloak` (the display name from the create-provider step).
3. Click it. The browser redirects to Keycloak, you authenticate as `alice`, Keycloak redirects back to certctl, and you land on the dashboard.
4. Navigate to **Auth → Sessions**. You should see a row with your own actor ID, the IP you logged in from, and the current timestamp under "last seen".
### Audit trail
```bash
curl https://<your-certctl-host>:8443/api/v1/audit?category=auth \
-H "Authorization: Bearer ${CERTCTL_API_KEY}" | jq '.events[] | select(.action == "auth.oidc_login_succeeded")'
```
You should see a row for the login above, with `details.provider_id` matching the Keycloak provider's id and `details.subject` set to the Keycloak user's `sub` claim (typically a UUID).
### JWKS-rotation drill
Operator action when Keycloak rotates its realm signing key:
1. In Keycloak: **Realm settings → Keys → Providers → Add provider → rsa-generated**, set priority higher than the current key (e.g. 200), enabled = on, active = on.
2. In certctl: GUI → **Auth → OIDC Providers → Keycloak → Refresh discovery cache** button. Or the CLI / MCP equivalent: `POST /api/v1/auth/oidc/providers/<id>/refresh`.
3. Run another login. The new ID token is signed under the new key; the certctl service validates it against the freshly-fetched JWKS doc.
The Phase 10 integration test `TestKeycloakIntegration_JWKSRotation_RefreshKeysPicksUpNewKey` exercises this exact flow end to end.
## Troubleshooting
**"Discovery doc fetch failed" at provider creation.**
The most common cause is a wrong issuer URL — typo in realm name, missing `/realms/` segment, or HTTP→HTTPS redirect that the Go client doesn't follow without explicit headers. Curl the URL manually:
```
curl -v https://<keycloak-host>/realms/<realm-name>/.well-known/openid-configuration
```
If that returns 404, fix the realm name. If it returns 200 but certctl still fails, check `cmd/server` logs for the wrapped error.
**"IdP downgrade-attack defense" rejected provider creation.**
Keycloak's realm has a signing key advertised in `id_token_signing_alg_values_supported` that's in certctl's deny-list (HS256/HS384/HS512/`none`). Check **Realm settings → Keys → Providers** — disable any HMAC key providers and re-create the provider in certctl.
**Login redirects to Keycloak, the user authenticates, but the callback redirects back to `/login` with "no roles assigned".**
The user authenticated successfully but their groups didn't match any configured mapping (`ErrGroupsUnmapped`). Check:
- The user is actually a member of the group you mapped (Users → user → Groups tab in Keycloak).
- The group-membership mapper is configured correctly (Clients → certctl → Client scopes → certctl-dedicated → mappers → groups → "Full group path: off" matters).
- The group name in your certctl mapping exactly matches what Keycloak emits — case-sensitive, no leading slash if "Full group path: off".
You can confirm what Keycloak is actually emitting by decoding the ID token at jwt.io against the Keycloak public key, or by enabling certctl's debug logging on the OIDC service for one login (logs are scrubbed of token contents per the Phase 3 token-leak hygiene contract; debug logs surface only the resolved group list and the mapping decision).
**"id_token verify failed: token used before issued"**
Clock skew between Keycloak and certctl-server. Either align both to NTP, or bump `iat_window_seconds` on the OIDC provider config (default 300 = 5 minutes). The certctl service caps `iat_window_seconds` at 600.
**"oidc: pre-login session not found or already consumed"**
The user clicked the OIDC login button, then the browser tab idled past the 10-minute pre-login TTL OR the user opened the IdP login in a new tab and consumed the row from the first one. Have them retry.
**"oidc: state parameter mismatch (replay or forgery)"**
Either the user double-submitted a callback URL (clicked it twice from email or browser history), or a CSRF attempt. The pre-login row is single-use; second consumption returns `ErrPreLoginNotFound`. Have them retry from the login page.
**Sessions revoked but the user can still hit the API.**
Check the Phase 4 session contract: the cookie is HMAC-validated on every request, but the actual database row is what `Revoke` deletes. If your reverse proxy is caching the response or the `certctl_session` cookie wasn't actually cleared on the client, the cookie will hit the server's session middleware which will return 401 on the missing-row lookup. The middleware never serves stale data; the issue is upstream of certctl in this case.
## Validation checklist
Before signing off this runbook for production rollout, validate these end-to-end:
- [ ] `auth.oidc_provider_created` audit row appears after the create-provider POST.
- [ ] `Sign in with Keycloak` button renders on the login page after `getAuthInfo` returns the configured provider.
- [ ] A user with mapped groups completes the auth-code flow and lands on the dashboard.
- [ ] A user WITHOUT mapped groups gets the "no roles assigned" landing (not the dashboard).
- [ ] The `auth.oidc_login_succeeded` and `auth.oidc_login_failed` audit rows correctly distinguish the two cases.
- [ ] The Sessions page shows the new session, with self-pill on the caller's row.
- [ ] Revoking the session via the GUI causes the next API request from that browser to 401 + redirect to login.
- [ ] Running the JWKS-rotation drill (steps above) does not break in-flight logins; rotated tokens validate against the refreshed JWKS.
- [ ] Editing the provider with `client_secret` blank preserves the existing ciphertext (operator confirms by reading the `oidc_providers.client_secret_encrypted` column before + after the PUT — bytes unchanged).

# Okta OIDC runbook
> Last reviewed: 2026-05-10
This runbook wires certctl's OIDC SSO surface against [Okta](https://www.okta.com/), a commercial cloud IdP. Okta offers a free developer tier (`https://dev-NNNNN.okta.com`) suitable for evaluation; production runs on a paid Workforce Identity tenant.
For the canonical reference + mental model, read [keycloak.md](keycloak.md) first; this runbook only documents the Okta-specific deltas.
## Prerequisites
**On the Okta side:**
- A Workforce Identity tenant (or free Developer Edition account at <https://developer.okta.com/signup/>).
- Super Admin or Application Admin role in your Okta tenant.
- Network reachability from certctl-server to `https://<your-org>.okta.com/.well-known/openid-configuration` OR to a custom authorization server endpoint if you're using one (`https://<your-org>.okta.com/oauth2/<auth-server-id>/.well-known/openid-configuration`).
**On the certctl side:** same as Keycloak.
## IdP-side configuration
### 1. Create the OIDC application
In the Okta admin console:
**Applications → Applications → Create App Integration**:
- Sign-in method: **OIDC - OpenID Connect**.
- Application type: **Web Application**.
- Click **Next**.
App config:
- App integration name: `certctl`.
- Logo: optional.
- Grant types: **Authorization Code** (CHECK). Leave Refresh Token unchecked unless you have a specific reason — certctl doesn't currently use refresh tokens.
- Sign-in redirect URIs: `https://<your-certctl-host>:8443/auth/oidc/callback`.
- Sign-out redirect URIs: optional; leave empty unless you also configure RP-initiated logout.
- Trusted Origins: leave default.
- Assignments → Controlled access: **Limit access to selected groups** (recommended; pick the `certctl-*` groups from step 3 below).
- Click **Save**.
On the saved app's **General** tab, copy the **Client ID** and **Client secret** (under Client Credentials). The secret is shown once on creation — copy it immediately or rotate via "Generate new secret".
### 2. Pick or create an authorization server
Okta has TWO authorization-server tiers:
- **The Org Authorization Server** at `https://<your-org>.okta.com` — emits ID tokens with limited claims; cannot host custom claims directly. Use for the simplest setup.
- **A Custom Authorization Server** at `https://<your-org>.okta.com/oauth2/<auth-server-id>` — fully configurable scopes + claims + access policies. The free developer tier ships with a default custom server at `/oauth2/default`. Recommended for production.
For this runbook we use the default custom server: `https://<your-org>.okta.com/oauth2/default`.
### 3. Create the groups + assign users
**Directory → Groups → Add Group**:
- Repeat for `certctl-engineers`, `certctl-viewers`, optionally `certctl-admins`.
**Directory → People → <user> → Groups**: assign each user to the appropriate `certctl-*` group(s).
Then go back to the App from step 1 and on the **Assignments** tab, assign the `certctl-*` groups to the application. Without this assignment Okta will reject the user's login attempt at the IdP layer with "User is not assigned to the client application".
### 4. Configure the groups claim
This is the load-bearing Okta-specific step. The default authorization server does NOT emit a `groups` claim out of the box — you have to define it.
**Security → API → Authorization Servers → default → Claims → Add Claim**:
- Name: `groups`.
- Include in token type: **ID Token, Always** (also tick Access Token if you want the userinfo-fallback path to work).
- Value type: **Groups**.
- Filter: pick **Matches regex** with the value `certctl-.*` so only the `certctl-*` groups are emitted (saves on token size; users in dozens of unrelated groups get a bloated token otherwise).
- Disable claim: off.
- Include in: **Any scope** (or pin to `openid` if you want the claim only on the certctl-flow).
- Click **Create**.
### 5. (Optional) Add `email` and `profile` claims
The default custom server already emits `email` and `name` under the `profile` and `email` scopes — no action needed unless you've stripped them from a custom config.
## certctl-side configuration
```bash
curl -X POST https://<your-certctl-host>:8443/api/v1/auth/oidc/providers \
-H "Authorization: Bearer ${CERTCTL_API_KEY}" \
-H "Content-Type: application/json" \
-d '{
"name": "Okta",
"issuer_url": "https://your-org.okta.com/oauth2/default",
"client_id": "<paste-from-step-1>",
"client_secret": "<paste-from-step-1>",
"redirect_uri": "https://certctl.example.com:8443/auth/oidc/callback",
"groups_claim_path": "groups",
"groups_claim_format": "string-array",
"fetch_userinfo": false,
"scopes": ["openid", "profile", "email"],
"iat_window_seconds": 300,
"jwks_cache_ttl_seconds": 3600
}'
```
Notes:
- `issuer_url` MUST match exactly what Okta emits as the `iss` claim. For the default custom server it's `https://<your-org>.okta.com/oauth2/default` (no trailing slash). The org server's issuer is just `https://<your-org>.okta.com` (no `/oauth2/...` path). Mismatching either side trips certctl's `ErrIssuerMismatch` sentinel.
- The `groups` scope is NOT required in the scopes list — Okta emits the claim based on the claim definition's "Include in: any scope" setting. Adding `groups` to the scopes list is harmless if your custom server has the scope defined.
Add the group→role mappings: `certctl-engineers` → `r-operator`, `certctl-viewers` → `r-viewer`, `certctl-admins` → `r-admin`.
## Verification
End-to-end login + audit + Sessions checks are identical to Keycloak.
**Okta-specific:** the audit row's `details.subject` will be Okta's user UID (a 20-char alphanumeric string starting with `00u`), stable across email changes. The certctl `users` table's `oidc_subject` column will hold this UID.
**Optional Okta smoke test in CI:** Phase 10 ships an opt-in smoke test at `internal/auth/oidc/integration_okta_smoke_test.go` (build tags `integration && okta_smoke`). Set `OKTA_ISSUER` + `OKTA_CLIENT_ID` + `OKTA_CLIENT_SECRET` env vars and run `make okta-smoke-test` to drive a discovery + RefreshKeys round-trip against your live tenant. Pre-reqs: enable the Resource Owner Password (ROPC) grant on the application (Sign-On tab → Grant types → Resource Owner Password) for the smoke test only; production certctl uses auth-code-with-PKCE.
**JWKS-rotation drill:** Okta auto-rotates signing keys every ~3 months and publishes the new key alongside the old in the JWKS doc for ~1 month overlap. Manual rotation: **Security → API → Authorization Servers → default → Keys → "Generate new key"**. After rotation, click "Refresh discovery cache" in certctl's GUI; new tokens validate immediately.
## Troubleshooting
**"User is not assigned to the client application" at the Okta login screen.**
You created the app + the user but didn't assign the user to the app via a group. Either assign the user directly (App → Assignments → Assign to People) or assign the `certctl-*` groups to the app (App → Assignments → Assign to Groups).
**Login completes but `groups` claim is empty in the ID token.**
Most common Okta gotcha — the default custom server doesn't emit `groups` until you define the claim (step 4 above). Decode the ID token at jwt.io to confirm. If the claim is defined but empty, check the regex filter in step 4 — `certctl-.*` matches names like `certctl-engineers` but NOT `engineers`.
**`ErrIssuerMismatch` after correctly configuring the discovery URL.**
The issuer claim Okta puts in the ID token MUST match `OIDCProvider.IssuerURL` byte-for-byte, including trailing slash. The default custom server emits `https://<your-org>.okta.com/oauth2/default` (no trailing slash); the org server emits `https://<your-org>.okta.com`. Don't append a trailing slash to either.
**Login succeeds but the certctl `User.Email` is empty.**
The `email` scope wasn't requested OR the user's email isn't verified at Okta. Add `email` to the certctl scopes config and ensure Okta's user has a verified primary email.
**Okta returns "PKCE code verifier required".**
The certctl service hard-codes PKCE-S256 on every login (RFC 9700 mandate). If Okta is rejecting the verifier, the most likely cause is a misconfigured app type — confirm the Okta application is "Web Application" (which supports auth-code + PKCE), not "Single-Page Application" (which has different token-binding rules) or "Native App".
**Custom-server access policies blocking the login.**
By default the `default` custom authorization server has an "Access Policy" with one rule allowing all clients + all users. If you've tightened this (production hygiene), add a rule that allows the `certctl` client + the `certctl-*` groups: **Security → API → Authorization Servers → default → Access Policies → <policy> → Add Rule**.
## Validation checklist
Same as [keycloak.md](keycloak.md#validation-checklist), with Okta-specific values + the access-policy check above.

#### Revoke: legacy "all variants" vs scope-selective (Audit 2026-05-11 A-4)
`DELETE /v1/auth/keys/{id}/roles/{role_id}` runs in one of two modes,
selected by presence of the optional query parameters:
- **No query params (legacy "revoke all variants")** — every scoped grant of
this role held by this actor is dropped. Idempotent: zero-row deletes
return 204 (no error). This is the pre-A-4 behaviour and remains the
default for the CLI / GUI buttons that don't know about scope.
```bash
# Drop EVERY variant of r-operator from alice (global, profile-scoped,
# issuer-scoped — all gone).
curl -X DELETE https://certctl.example.com/api/v1/auth/keys/alice/roles/r-operator
```
- **`?scope_type=` (+ optional `?scope_id=`)** — drop ONE variant. Used
when an actor holds the same role at multiple scopes (HIGH-10 made
that representable; A-4 makes it selectively revocable).
`scope_type=global` requires `scope_id` to be absent; `scope_type=profile`
/ `issuer` require `scope_id`. No match returns 404 so operators get
feedback when they target a scope variant the actor doesn't hold.
```bash
# Alice holds r-operator scoped to p-acme AND p-globex.
# Drop ONLY the p-acme grant; the p-globex grant stays.
curl -X DELETE 'https://certctl.example.com/api/v1/auth/keys/alice/roles/r-operator?scope_type=profile&scope_id=p-acme'
# Drop ONLY the global grant of r-operator (keeps any profile / issuer variants):
curl -X DELETE 'https://certctl.example.com/api/v1/auth/keys/alice/roles/r-operator?scope_type=global'
```
The audit row's `details` payload records which mode fired —
`scope: "all_variants"` for the legacy path, or the explicit
`scope_type` + `scope_id` for selective revoke — so SOC / SIEM can
distinguish wide cleanups from targeted demotions in the access log.

### OIDC federation (Bundle 2 Phases 1-7)
Bundle 2 adds OIDC SSO on top of the API-key + RBAC foundation.
Operators configure one or more identity providers (Keycloak,
Authentik, Okta, Auth0, Entra ID, or Google Workspace via Keycloak
broker); end users sign in at the IdP, certctl validates the
returned ID token, and a session cookie is minted.
The token-validation pipeline pins:
- Algorithm allow-list: RS256 / RS512 / ES256 / ES384 / EdDSA only.
HS256 / HS384 / HS512 / `none` are rejected at the service-layer
sentinel level.
- IdP-downgrade-attack defense at provider creation AND every
RefreshKeys: the IdP's advertised
`id_token_signing_alg_values_supported` is intersected with the
allow-list; a provider that advertises HS-family is rejected
before any token is signed under the weak alg.
- Exact `iss` match (`ErrIssuerMismatch`).
- `aud` membership + `azp` for multi-aud tokens (per OIDC core
§3.1.3.7 step 5).
- `at_hash` REQUIRED-when-access_token-present (Phase 3 tightening
of the spec MAY → MUST so a substituted access token cannot
ride alongside a clean ID token).
- Single-use state + nonce (32-byte random server-generated;
atomic `DELETE...RETURNING` on consume).
- PKCE-S256 mandatory; `plain` rejected.
- Configurable `iat` window (default 300s, capped 600s).
- JWKS cache with operator-triggered RefreshKeys + auto-refresh on
TTL expiry (default 3600s); JWKS-fetch failure during a key
rotation returns 503 to the in-flight login (existing sessions
untouched).
OIDC `client_secret` is encrypted at rest via AES-256-GCM (v3 blob
format: magic 0x03 + salt(16) + nonce(12) + ciphertext+tag) using
the `CERTCTL_CONFIG_ENCRYPTION_KEY` passphrase. The encryption
invariant is pinned by an integration test
(`internal/repository/postgres/oidc_encryption_invariant_test.go`)
that asserts ciphertext != plaintext + correct blob shape +
round-trip recovery + wrong-passphrase fails.
Per-IdP setup guides at
[`oidc-runbooks/index.md`](oidc-runbooks/index.md) cover Keycloak,
Authentik, Okta, Auth0, Entra ID, and Google Workspace.
### Sessions + back-channel logout (Bundle 2 Phases 4-6)
Successful OIDC login mints a session cookie:
`v1.<session_id>.<signing_key_id>.<base64url-no-pad(HMAC-SHA256)>`.
The HMAC input is **length-prefixed** as `len:sid:len:kid` to defeat
concatenation-collision attacks on bare-concat designs. Cookie
attributes:
- `HttpOnly=true` (no JS access; defends XSS cookie theft).
- `Secure=true` (HTTPS-only; defends network MITM).
- `SameSite=Lax` default (configurable to Strict via
`CERTCTL_SESSION_SAMESITE`).
- `Path=/`, host-only.
Idle timeout default 1h; absolute timeout default 8h; both
configurable via `CERTCTL_SESSION_IDLE_TIMEOUT` and
`CERTCTL_SESSION_ABSOLUTE_TIMEOUT`. The scheduler's
`sessionGCLoop` (default 1h interval) sweeps expired rows.
CSRF defense: plaintext CSRF token in the JS-readable
`certctl_csrf` cookie (intentionally `HttpOnly=false` for the GUI
to echo into the `X-CSRF-Token` header); SHA-256 hash on the
session row; `subtle.ConstantTimeCompare` in `CSRFMiddleware`.
API-key actors are CSRF-exempt (no session row in context).
Session signing keys rotate via `RotateSigningKey`; the old key
stays valid for `CERTCTL_SESSION_SIGNING_KEY_RETENTION` (default
24h) so existing cookies validate during rollover. Past retention,
the old key's row is dropped and any cookie still signed under it
returns `ErrSigningKeyNotFound`. `EnsureInitialSigningKey` is
fail-fatal at server boot.
Back-channel logout per **OpenID Connect Back-Channel Logout 1.0**
(NOT RFC 8414): `POST /auth/oidc/back-channel-logout` accepts a
JWT-signed logout token from the IdP, validates the JWT against
the IdP's JWKS (same alg allow-list as login), pins required
claims (`iss` / `aud` / `iat` / `jti` / `events`; exactly one of
`sub` / `sid`; `nonce` MUST be absent), defeats replay via
`jti`-based deduplication, and revokes matching sessions.
For threat-model coverage of these surfaces, see
[`auth-threat-model.md`](auth-threat-model.md). For the
operator-runnable performance baselines, see
[`auth-benchmarks.md`](auth-benchmarks.md).
### OIDC first-admin bootstrap (Bundle 2 Phase 7)
Coexists with Bundle 1's env-var-token bootstrap. When the
operator sets `CERTCTL_BOOTSTRAP_ADMIN_GROUPS` + (optionally)
`CERTCTL_BOOTSTRAP_OIDC_PROVIDER_ID`, the first user with one of
those IdP groups becomes admin on first login per tenant.
Subsequent users go through normal mapping. The admin-existence
probe ensures only one wins between the two bootstrap paths;
once any actor holds `r-admin`, the OIDC bootstrap hook silently
falls through to normal mapping. Audit row on every grant
(`bootstrap.oidc_first_admin`, `event_category=auth`).
### Break-glass admin (Bundle 2 Phase 7.5)
Default-OFF (`CERTCTL_BREAKGLASS_ENABLED=false`). When enabled,
the local-password admin path bypasses OIDC + group-claim layers;
intended ONLY for SSO-broken incidents.
- Argon2id with OWASP 2024 params (m=64 MiB, t=3, p=4, 16-byte
salt, 32-byte output, per-password random salt, PHC-format
hash). Hash column is `json:"-"` so handlers cannot wire-leak.
- Lockout state machine: 5 failures (default; configurable via
`CERTCTL_BREAKGLASS_LOCKOUT_THRESHOLD`) within 1h reset window
(`_LOCKOUT_RESET_INTERVAL`) trips a 30s lockout (`_LOCKOUT_DURATION`).
Atomic single-statement IncrementFailure defeats concurrent
racing attempts.
- Constant-time across all failure paths via `verifyDummy()` —
wrong-password / locked-account / no-actor all take statistically
indistinguishable time.
- Surface invisibility: when disabled, ALL four endpoints return
HTTP 404 (NOT 403). Scanners cannot distinguish "endpoint
disabled" from "endpoint doesn't exist".
- WARN log at server boot when `ENABLED=true`; audit row on every
break-glass login (`auth.breakglass_login_*`,
`event_category=auth`); WebAuthn/FIDO2 second factor pairing
on the v3 roadmap (Decision 12).
Operator should DISABLE break-glass within 24h of SSO recovery
to avoid a permanent backdoor; the runbook at
[`auth-threat-model.md#break-glass-risks-phase-75`](auth-threat-model.md)
documents the full state machine.
### Demo-to-production cutover (Audit 2026-05-11 A-8)
Migration `000029_rbac.up.sql` unconditionally seeds an
`actor-demo-anon → r-admin` row into `actor_roles`. This row is the
runtime principal injected by the demo-mode middleware when
`CERTCTL_AUTH_TYPE=none`. Under any non-`none` auth type the row is
DORMANT — the middleware chain never resolves to it. But its existence
is a footgun: a future regression that resolves an unauthenticated
request to `actor-demo-anon` (a misrouted CORS preflight, a fallback in
a new auth-exempt route) would silently re-elevate to admin.
certctl-server detects this residue at startup and emits a WARN log +
an `auth.demo_residual_grants_detected` audit row listing every grant
present on `actor-demo-anon`. **Every production deploy will see this
WARN on first boot** — the migration baseline is part of the install,
not a side effect of running demo mode.
Operator workflow at production cutover:
1. Drain the WARN by calling the cleanup endpoint with an admin API key:
```bash
curl -X POST --cacert deploy/test/certs/ca.crt \
-H "Authorization: Bearer $ADMIN_KEY" \
https://certctl.example.com:8443/api/v1/auth/demo-residual/cleanup
# → {"removed": 1}
```
The endpoint is gated `auth.role.assign` (admin-class) and refuses
to run when `CERTCTL_AUTH_TYPE=none` (HTTP 503 — the residue IS the
active runtime state at that auth type). The cleanup is idempotent;
a second call returns `{"removed": 0}` and still leaves an audit row.
Equivalent SQL for operators preferring direct DB access:
```sql
DELETE FROM actor_roles WHERE actor_id = 'actor-demo-anon';
```
2. To make subsequent boots refuse startup if the row reappears (the
most paranoid stance), set:
```
CERTCTL_DEMO_MODE_RESIDUAL_STRICT=true
```
With the flag set, any `actor-demo-anon` row under a non-`none`
auth type causes certctl-server to log the WARN AND exit non-zero
before binding the HTTPS listener. Default is `false` (WARN only).
3. The CI guard `scripts/ci-guards/no-new-synthetic-admin.sh` pins the
set of source files that may reference the `actor-demo-anon` literal.
New runtime code paths that resolve to the synthetic actor are
rejected at PR time so the credibility gap stays closed.
### Migrating an existing deployment to OIDC
A Bundle-1-merged deployment that wants to add OIDC follows the
step-by-step at
[`docs/migration/oidc-enable.md`](../migration/oidc-enable.md):
configure CERTCTL_CONFIG_ENCRYPTION_KEY, pick + configure an IdP
per the relevant runbook, configure the certctl-side OIDCProvider
+ group→role mappings, verify the login flow against a single
test user, then announce the SSO endpoint to the rest of the
organization.

# Authentication standards implemented
> Last reviewed: 2026-05-10
This document is an honest informational reference for operators, external testers, and acquirers who want to know which RFCs and standards Auth Bundle 1 (RBAC) and Auth Bundle 2 (OIDC + sessions + back-channel logout + break-glass) implement, and which CWE weakness classes the implementation closes. Every row points at a real file or migration in this repository.
This document is intentionally NOT a compliance-mapping doc. The operator retired the framework-mapping subtree (`docs/compliance/{index,soc2,pci-dss,nist-sp-800-57}.md`) on 2026-05-05; framework-name-drops (SOC 2 / PCI-DSS / HIPAA / NIST SSDF / FedRAMP) are also swept from prose mentions across `README.md` and `docs/` per that decision. RFC and CWE references stay because they are precise technical pointers; framework labels were marketing-flavored and prone to overclaim. If you are an auditor mapping certctl's controls to a framework, treat the rows below as evidence and do the framework mapping yourself against the framework you are auditing against.
For the wider security posture, see [`security.md`](../operator/security.md). For the threat model behind these controls, see [`auth-threat-model.md`](../operator/auth-threat-model.md). For the per-IdP setup guides, see [`oidc-runbooks/index.md`](../operator/oidc-runbooks/index.md).
## Table 1: RFCs and standards implemented end-to-end
Each row carries at least one negative test (a test that asserts the fail-closed branch fires when a malformed input violates the spec).
| Standard | What we implement | Source | Negative-test anchor |
|---|---|---|---|
| RFC 6749 (OAuth 2.0) | Authorization-code grant via OIDC; confidential-client credentials only | `internal/auth/oidc/service.go` (HandleAuthRequest, HandleCallback) | `internal/auth/oidc/service_test.go` (21+ negatives covering wrong aud / wrong iss / expired / etc.) |
| RFC 7636 (PKCE) | S256 challenge mandatory; `plain` rejected at the service-layer sentinel; verifier persisted in pre-login row, single-use | `internal/auth/oidc/service.go` (oauth2.S256ChallengeOption hard-coded), `internal/auth/oidc/prelogin.go` | `TestService_PKCEPlainRejectedSentinel`, `TestService_StateReplayDeniedByConsumeOnce` |
| RFC 7519 (JWT) | ID-token validation via go-oidc; service-layer alg allow-list (RS256/RS512/ES256/ES384/EdDSA); HS-family + `none` rejected | `internal/auth/oidc/service.go` (disallowedAlgs map, isDisallowedAlg) | `TestService_HandleCallback_RejectsHSAlgsConfusion`, `TestService_IdPDowngradeDefense_RejectsHSAdvertised` |
| RFC 7517 (JWK) | JWKS fetch + cache + rotation handled transparently by coreos/go-oidc; operator-triggered RefreshKeys + auto-refresh on TTL expiry | `internal/auth/oidc/service.go` (RefreshKeys; cfg.JWKSCacheTTLSeconds default 3600) | `TestService_RefreshKeys_CatchesPostLoadDowngrade`, `TestKeycloakIntegration_JWKSRotation_RefreshKeysPicksUpNewKey` (Phase 10 integration) |
| OIDC Core 1.0 §3.1.3.7 | `iss` exact match, `aud` membership, `azp` for multi-aud, `at_hash` REQUIRED-when-access_token-present (Phase 3 tightening of the spec MAY → MUST), `nonce` constant-time-compare | `internal/auth/oidc/service.go` (HandleCallback steps 5-9) | `TestService_HandleCallback_RejectsWrongAudience`, `TestService_HandleCallback_AZPRequiredOnMultiAud`, `TestService_HandleCallback_ATHashRequiredWhenAccessTokenPresent`, `TestService_HandleCallback_RejectsNonceMismatch` |
| OIDC Core 1.0 §5.3.2 (UserInfo endpoint) | Optional fallback when ID-token groups claim is empty; bounded by configured FetchUserinfo bool | `internal/auth/oidc/service.go` (fetchUserinfoGroups) | 4-case userinfo-fallback matrix in `service_test.go` (happy + endpoint-missing + endpoint-failing + userinfo-also-empty) |
| OpenID Connect Back-Channel Logout 1.0 | `events` claim + `sid`/`sub` revocation; `nonce` MUST be absent; `jti`-based replay defense | `internal/api/handler/auth_session_oidc.go` (BackChannelLogout, DefaultBCLVerifier) | 6 negatives in `auth_session_oidc_test.go`: BCL missing events, BCL nonce-present, BCL unknown-key-sig, etc. |
| RFC 6265 (HTTP State Management) | Session cookie attributes: `Secure` + `HttpOnly` + `SameSite=Lax` (default; configurable to Strict via `CERTCTL_SESSION_SAMESITE`); `Path=/`; host-only | `internal/auth/session/service.go` (cookie minting), `internal/api/handler/auth_session_oidc.go` (Set-Cookie wiring) | Phase 6 middleware-chain test matrix (7 cases) in `internal/auth/session/middleware_test.go` |
| RFC 9700 (OAuth 2.0 Security Best Current Practice) | PKCE mandatory; no implicit flow; strict redirect_uri (registered + exact-match per OIDCProvider.RedirectURI); state non-guessable (32-byte random); single-use | `internal/auth/oidc/service.go`; `OIDCProvider.Validate()` enforces redirect_uri shape | `TestOIDCProvider_Validate_RejectsHTTPRedirectInProd`, state-replay test |
| RFC 8414 (OAuth 2.0 Authorization Server Metadata) | Discovery doc fetched via go-oidc at provider creation + RefreshKeys; `id_token_signing_alg_values_supported` consulted for IdP-downgrade-attack defense | `internal/auth/oidc/service.go` (getOrLoad, guardAdvertisedAlgs) | `TestService_IdPDowngradeDefense_RejectsHSAdvertised` and `RejectsNoneAdvertised` |
| RFC 7633 (X.509 TLS Feature Extension; Must-Staple) | Per-profile certctl issuance flag; out-of-scope for Bundle 2 but cited here because RFC 7633 OID `id-pe-tlsfeature` is in the same crypto-stack umbrella | `internal/connector/issuer/local/local.go` | Bundle 9 SCEP master-bundle Phase 5.6 tests; not Bundle-2 territory |
| RFC 8555 §7 (ACME directory metadata) | certctl-side ACME server tier; out-of-scope for Bundle 2 but cited because it shares the alg-pinning + nonce-handling discipline that Bundle 2 carries forward | `internal/api/handler/acme/*` | per-route handler tests in `internal/api/handler/acme/` |
| RFC 7515 (JWS) | JWS verification delegated to go-oidc/v3 + go-jose/v4; alg pin enforced at `gooidc.NewIDTokenVerifier` config + service-layer re-check | `internal/auth/oidc/service.go` (oauthConfig + verifier wiring) | `TestService_HandleCallback_RejectsExpired` and `TestService_HandleCallback_RejectsIATInFuture` |
## Table 2: CWE / weakness classes the implementation closes
Each row points at the file(s) that implement the defense and the test file(s) that pin the invariant.
| CWE | Description | Where defended | Where pinned |
|---|---|---|---|
| CWE-287 (Improper Authentication) | Session-cookie HMAC verification (length-prefixed input defeats concat-collision) + alg-pinned ID-token verify | `internal/auth/session/service.go` (computeHMAC, parseCookie, Validate); `internal/auth/oidc/service.go` (HandleCallback) | `TestComputeHMAC_LengthPrefixDefeatsConcatCollision`; `TestService_Validate_ConcatenationCollisionDefeatedByLengthPrefix`; full Phase 3 21+ negatives matrix |
| CWE-352 (Cross-Site Request Forgery) | Double-submit cookie + `SameSite=Lax`/`Strict` + hashed CSRF token on session row; constant-time compare in CSRFMiddleware | `internal/auth/session/middleware.go` (CSRFMiddleware) | Phase 6 7-case middleware-chain matrix (`internal/auth/session/middleware_test.go`); `TestSessionMiddleware_CSRFRequiredOnStateChangingMethods` |
| CWE-384 (Session Fixation) | Session ID is opaque random `ses-<base64url>` (32 bytes entropy) generated server-side at login; cookie value rotates on every login (no inheritance from pre-login); CSRF token rotates alongside | `internal/auth/session/service.go` (Create, RotateCSRFToken) | `TestService_Create_AssignsFreshSessionID`; CSRF rotation pinned via `TestService_RotateCSRFToken_AfterLogin` |
| CWE-294 (Authentication Bypass by Capture-Replay) | Single-use state, single-use nonce (both stored in pre-login row, atomic `DELETE...RETURNING` on consume); single-use authorization code (Keycloak/IdP-side); `jti`-based BCL replay defense | `internal/auth/oidc/prelogin.go` (LookupAndConsume); `internal/api/handler/auth_session_oidc.go` (BCL handler) | `TestService_StateReplayDeniedByConsumeOnce`; `TestService_HandleCallback_RejectsForgedPreLoginCookie`; BCL replay negative in handler tests |
| CWE-916 / CWE-329 (Use of Password Hash With Insufficient Computational Effort / Use of a Key Past its Expiration Date) | Argon2id with OWASP 2024 params (m=64 MiB, t=3, p=4, 16-byte salt, 32-byte output) for break-glass passwords; per-credential random salt; PHC-format hash | `internal/auth/breakglass/service.go` (HashPassword, VerifyPassword); v3 ciphertext blob format with PBKDF2-SHA256 600,000 rounds for config-at-rest encryption | `TestPhase7_5_HashPasswordOWASP2024Params`; `TestPhase7_5_HashFormatPHC`; `internal/crypto/encryption_test.go` for v3 PBKDF2 floor |
| CWE-307 (Improper Restriction of Excessive Authentication Attempts) | Failure count + lockout window on break-glass credential; threshold default 5, reset window default 1h, lockout duration default 30s; atomic single-statement IncrementFailure defeats concurrent racing attempts | `internal/auth/breakglass/service.go` (Login, IncrementFailure); `internal/repository/postgres/breakglass.go` | `TestPhase7_5_LockoutAfterThresholdFailures`; `TestPhase7_5_FailureCountResetsAfterWindow` |
| CWE-345 (Insufficient Verification of Data Authenticity) | OIDC `at_hash` REQUIRED-when-access_token-present ties access token to ID token (Phase 3 tightening of OIDC core MAY → MUST); OIDC `iss` + `aud` + `azp` checks ensure token came from the configured IdP for the configured client | `internal/auth/oidc/service.go` (HandleCallback steps 5-9, atHashMatches) | `TestService_HandleCallback_ATHashRequiredWhenAccessTokenPresent`; `TestService_HandleCallback_RejectsATHashMismatch` |
| CWE-200 (Information Exposure) | Token-leak hygiene tests on every secret-bearing path: ID tokens, access tokens, refresh tokens, authorization codes, PKCE verifiers, state, nonce, signing keys, break-glass passwords NEVER appear in any log line at any level | `internal/auth/oidc/service.go`, `internal/auth/session/service.go`, `internal/auth/breakglass/service.go` (all log calls audited); `internal/service/audit_redact.go` (Bundle 6 redactor) | `internal/auth/oidc/logging_test.go` (4 grep-asserts); `internal/auth/breakglass/service_test.go` (token-leak hygiene + json.Marshal probe); `internal/auth/bootstrap/service_test.go` (Bundle 1 pattern) |
| CWE-770 (Allocation of Resources Without Limits or Throttling) | Per-IP rate limit on `/auth/breakglass/login` via the global middleware.NewRateLimiter (default RPS / burst from `CERTCTL_RATE_LIMIT_*` env vars) wrapped around the entire mux; the breakglass login endpoint inherits this protection. Per-route override available via `middleware.NewRateLimiter` per-bucket configuration if the operator wants stricter caps | `cmd/server/main.go` (rateLimiter wiring at the root middleware stack); `internal/api/middleware/middleware.go` (NewRateLimiter) | `internal/api/middleware/ratelimit_test.go`; `internal/api/middleware/ratelimit_keyed_test.go` |
| CWE-330 (Use of Insufficiently Random Values) | `crypto/rand` for state, nonce, PKCE verifier (via `oauth2.GenerateVerifier`), session signing keys (32 random bytes), session IDs (`ses-<base64url-no-pad>` from 32 random bytes), pre-login IDs (`pl-<base64url-no-pad>` from 16 random bytes), CSRF tokens (32 random bytes), break-glass salts (16 random bytes via `crypto/rand`) | `internal/auth/oidc/service.go` (randomB64URL); `internal/auth/session/service.go` (newOpaqueID, newCSRFToken); `internal/auth/oidc/prelogin.go` (newID); `internal/auth/breakglass/service.go` (HashPassword salt) | `TestPreLoginAdapter_CreatePreLogin_RNGFailure` (entropy-source error path); RNG failure pinned for every callsite |
| CWE-311 (Missing Encryption of Sensitive Data) | OIDC `client_secret` AES-256-GCM encrypted at rest (v3 blob format: magic 0x03 + salt(16) + nonce(12) + ciphertext+tag); session signing keys same scheme; empty `CERTCTL_CONFIG_ENCRYPTION_KEY` returns `ErrEncryptionKeyRequired` (fail-closed) | `internal/crypto/encryption.go` (EncryptIfKeySet, DecryptIfKeySet); `internal/api/handler/auth_session_oidc.go` (encryptClientSecret); `internal/auth/session/service.go` (KeyMaterialEncrypted) | `internal/repository/postgres/oidc_encryption_invariant_test.go` (Phase 13 invariant test: ciphertext != plaintext, v2/v3 blob shape, round-trip + wrong-passphrase fails) |
| CWE-326 (Inadequate Encryption Strength) | TLS 1.3 only on the certctl control plane (post-v2.2 milestone); HSTS-equivalent posture via HTTPS-only listener; AES-256-GCM for at-rest config encryption; PBKDF2-SHA256 600,000 rounds for v3 blob key derivation (OWASP 2024 floor) | `cmd/server/main.go` (TLS 1.3 listener config); `internal/crypto/encryption.go` (v3 PBKDF2 iteration count) | `TestServerTLSConfig_RejectsTLS12` (Bundle 5); `TestEncryption_V3IterationCount_PinnedAtOWASP2024Floor` |
| CWE-1004 (Sensitive Cookie Without HttpOnly) | Session cookie set with `HttpOnly=true`; CSRF cookie intentionally `HttpOnly=false` so the GUI can read it for the `X-CSRF-Token` header (the read is by-design per the double-submit-cookie pattern) | `internal/auth/session/service.go` (cookie attrs); `internal/api/handler/auth_session_oidc.go` (Set-Cookie wiring) | Cookie-attribute pinning in handler tests; documented in [auth-threat-model.md](../operator/auth-threat-model.md) "Session minting + cookies" subsection |
| CWE-614 (Sensitive Cookie in HTTPS Session Without 'Secure' Attribute) | Session + CSRF cookies set with `Secure=true`; rejected at cookie-write time on `http://` listeners (HTTPS-only control plane post-v2.2) | `internal/auth/session/service.go`; `cmd/server/main.go` HTTPS-only listener | TLS-listener tests in `cmd/server/`; cookie attrs pinned in handler tests |
| CWE-1275 (Sensitive Cookie with Improper SameSite Attribute) | Session cookie `SameSite=Lax` default (configurable to Strict via `CERTCTL_SESSION_SAMESITE`); CSRF defense via the double-submit pattern means `Lax` is sufficient even if the operator does not flip to Strict | `internal/auth/session/service.go` (cookie attrs); `internal/config/config.go` (SAMESITE env var) | Cookie-attribute pinning; SameSite enforcement is per-cookie |
## Bundle 1 (RBAC) standards covered separately
The above tables focus on Bundle 2's OIDC + sessions + back-channel logout + break-glass surface. Bundle 1's RBAC primitive carries its own implementation pointers; the Bundle 1 [`auth-threat-model.md`](../operator/auth-threat-model.md) section "Defenses Bundle 1 ships" enumerates the full RBAC + bootstrap + auditor + approval-workflow surface. CWE-pointers that apply to Bundle 1's surface:
- CWE-285 (Improper Authorization) — defended by the Phase 3 RequirePermission middleware + Authorizer.CheckPermission service-layer call. Pinned by 90+ tests across `internal/auth/` and `internal/service/auth/`.
- CWE-862 (Missing Authorization) — pinned by Phase 12's `phase12_protocol_allowlist_test.go` (asserts protocol endpoints are explicitly allowlisted, NOT silently bypassing the gate).
- CWE-863 (Incorrect Authorization) — pinned by the auditor-split invariant in `internal/domain/auth/auditor_test.go` (auditor role holds exactly `audit.read` + `audit.export` ONLY).
- CWE-732 (Incorrect Permission Assignment for Critical Resource) — five admin-only fine-grained perms (`cert.bulk_revoke`, `crl.admin`, `scep.admin`, `est.admin`, `ca.hierarchy.manage`) seeded into `r-admin` only; pinned by migration 000030 + `r-admin`-only seed test.
## What this document is NOT
To preserve the operator's 2026-05-05 retired-compliance-docs decision:
- This is NOT a SOC 2 / PCI-DSS / HIPAA / NIST SP 800-53 / NIST SSDF / FedRAMP framework-mapping doc.
- This is NOT a marketing claim that certctl "satisfies CC6.1" or "complies with §164.312(a)(2)(iii)" or any similar framework label.
- This IS an evidence list. An auditor doing framework mapping for their own compliance purposes can use this list as the source-of-truth pointer, then map each row to the framework control they are auditing against under their own judgment.
If you are an external tester, an operator's auditor, or an acquirer doing technical diligence, this document gives you concrete file paths to read and concrete tests to run. If you want a framework-mapping document, build it yourself against the rows here using the framework-mapping methodology your audit firm prescribes; this project does not own that mapping.

// Package breakglass — Auth Bundle 2 Phase 7.5 / break-glass admin service.
//
// Decision 4: operator-toggleable local-password admin for the SSO-broken
// case. No second factor in this bundle (WebAuthn pairs in v3 per
// Decision 12). The path exists so an admin can recover when OIDC is
// down; it is NOT for general human auth.
//
// Threat model (load-bearing):
//
// - Break-glass is a deliberate bypass of the SSO security boundary.
// An attacker who phishes the password OR finds it in a compromised
// password manager bypasses MFA, OIDC, and every group-claim gate.
// - Operators MUST keep CERTCTL_BREAKGLASS_ENABLED=false in steady-
// state. Enable only during SSO-broken incidents. Disable after
// recovery.
// - WebAuthn pairing (v3 per Decision 12) is the load-bearing second
// factor. Without it, break-glass is best treated as an
// emergency-only path.
// - Audit trail surfaces every break-glass action under
// event_category=auth; the auditor role can monitor for unexpected
// break-glass logins.
//
// Defense-in-depth (load-bearing):
//
// - Argon2id with OWASP-2024 parameters (m=64MiB, t=3, p=4, salt=16
// bytes, output=32 bytes). Per-password random salt; PHC-format
// hash for forward-compat parameter rotation.
// - subtle.ConstantTimeCompare on every password verify. Identical
// timing + identical error shape across the wrong-password,
// locked-account, and non-existent-actor paths so an attacker
// cannot probe whether a given actor has break-glass configured.
// - Lockout state machine: failure_count increments on every wrong
// attempt; threshold (default 5) trips locked_until = NOW() +
// duration (default 15m). Successful Authenticate resets the
// counter. Admin-initiated Unlock also resets.
// - Surface invisibility: when Service.Enabled() == false, every
// handler returns 404 (NOT 403) so the surface is invisible to
// scanners.
// - Token-leak hygiene: passwords NEVER appear in any log line at
// any level. Pinned by logging_test.go's slog buffer + grep-assert.
// - PasswordHash is `json:"-"` on the domain type so a misconfigured
// handler cannot wire-leak the hash via JSON marshaling.

// Bundle 2 Phase 14 — OIDC token validation benchmark (cold-cache).
//
// Build-tag-gated under `integration` so the heavy Keycloak boot (60-90s
// cold-pull) never lands in `go test -short` or the default
// `go test ./...` developer loop.
//
// What this measures: the JWKS-rotation cold-cache path. The IdP rotates
// its signing keys; the next certctl-side login attempt either fails
// validation (stale JWKS cache) or — once RefreshKeys clears the cache —
// re-fetches the discovery doc + JWKS over real HTTP and re-runs the
// IdP-downgrade-attack defense.
//
// The benchmark drives the post-rotation refresh path:
//
// 1. Boot Keycloak (Phase 10 fixture).
// 2. Configure the OIDC service against the live realm.
// 3. Pre-warm the JWKS cache.
// 4. RotateRealmKeys (admin REST API).
// 5. For each iteration:
// a. Call svc.RefreshKeys → forces a fresh discovery + JWKS fetch.
// b. Time the refresh + a subsequent HandleAuthRequest (which
// re-uses the freshly-loaded entry from cache).
// c. Measure the round-trip cost.
//
// Phase 14 target: p99 < 200ms.
//
// Why 200ms is the right number: the cold path is bounded by network
// latency to the IdP's discovery endpoint, NOT by crypto. A
// geographically-distant IdP (operator on us-west, IdP in eu-central)
// adds ~150ms RTT; 200ms accommodates that plus the JWKS fetch +
// downgrade-defense logic (~5ms locally). Steady-state OIDC is < 5ms
// because no network is involved; cold-cache is bounded by physics
// (the speed of light + TCP handshake to a remote endpoint).
//
// Run via:
// make benchmark-auth-coldcache # see Makefile target (Phase 14)

// Package oidc — Auth Bundle 2 Phase 7 / OIDC bootstrap hook.
//
// Phase 7 ships the "first OIDC login matching CERTCTL_BOOTSTRAP_ADMIN_GROUPS
// becomes admin" recovery path. This is Decision 3's preferred bootstrap:
// fresh deployments configure the OIDC provider + group mapping, and the
// first user who logs in via OIDC + carries any of the configured
// bootstrap admin groups is auto-granted r-admin. Subsequent logins fall
// through to normal group→role mapping.
//
// The hook is OPTIONAL — when not wired, OIDC behaves byte-identically
// to Phase 3. When wired, it runs after group resolution + user upsert
// and BEFORE the empty-mapping fail-closed check, so a fresh deployment
// with no group_role_mappings can still mint the first admin via the
// bootstrap path. The hook itself is responsible for the AdminExists
// probe (so admin-already-exists deployments fall through to normal
// mapping).
//
// Audit + lockout semantics:
//
// - The hook emits the bootstrap.oidc_first_admin audit row with
// event_category=auth on every successful first-admin grant.
// - The hook is one-shot per process: once an admin exists in the
// tenant, the AdminExists probe returns true and subsequent OIDC
// logins skip the bootstrap path entirely.
// - The hook NEVER grants admin to an actor whose groups don't match
// CERTCTL_BOOTSTRAP_ADMIN_GROUPS. The intersection is constant-time-
// length-irrelevant (it walks two slices); the relevant guarantee
// is that no group string can be inferred from the hook's pass /
// fail decision because the hook always emits the same audit row
// shape.

// Distinct from integration_keycloak_test.go's existing
// TestKeycloakIntegration_JWKSRotation_RefreshKeysPicksUpNewKey: that
// test calls `svc.RefreshKeys` explicitly between the rotate event and
// the second login (operator-driven path). This test deliberately does
// NOT call RefreshKeys — it exercises the IMPLICIT auto-refresh that
// MED-6 added inside HandleCallback's verify-error branch.
//
// The unit-test sibling lives in service_test.go::
// TestService_HandleCallback_MED6_AutoRefreshOnKidMiss; it uses an
// in-process mockIdP. Here we run against a real Keycloak realm so
// the test pins behavior against the actual go-oidc error strings
// emitted by a production-grade JWKS endpoint with multiple active
// keys + a key-priority change.
//
// Build-tagged `integration` so it doesn't run under `make test` /
// `go test -short`. Runs via `make keycloak-integration-test` which
// boots the Keycloak testcontainer.
// =============================================================================
// TestKeycloakIntegration_MED6_AutoRefreshOnKidMiss pins the MED-6
// recovery contract: after the realm rotates its signing key, the
// next /auth/oidc/callback request that arrives WITHOUT an explicit
// operator-initiated RefreshKeys must still succeed — HandleCallback
// detects the kid-not-in-cache shape and runs the one-shot refresh +
// retry internally.
//
// Plan:
// 1. Successful baseline login under the realm's original signing key
// (primes the certctl service's JWKS cache).
// 2. Rotate the realm's RSA key via the Keycloak admin API.
// 3. Run a fresh /auth/oidc/login → /auth/oidc/callback flow.
// - Keycloak signs the new ID token under the new (higher-priority)
// key.
// - certctl's verifier holds the pre-rotate JWKS in cache.
// - The verify trips kid-not-in-cache → MED-6 auto-refresh fires →
// second verify succeeds.
// 4. Assert the callback succeeded without the test having called
// RefreshKeys (which would mask the MED-6 path).
//
// Note: this is the Keycloak-against-real-IdP variant of MED-6's
// unit test. The unit test stays the canonical regression because
// it doesn't require the testcontainer; this test is the

// Bundle 2 Phase 10 — Keycloak end-to-end integration test.
//
// Drives the full OIDC service-layer flow against a live Keycloak
// container booted by testfixtures.StartKeycloak. Asserts the seven
// behaviors the Phase 10 prompt enumerates:
//
// 1. Discovery doc fetched, JWKS cached (TestKeycloakIntegration_RefreshKeysFetchesDiscoveryAndJWKS)
// 2. Login works with valid credentials (TestKeycloakIntegration_AuthCodeFlow_HappyPath)
// 3. Group claims parsed (same)
// 4. Group-role mapping applied (same; engineers→r-operator)
// 5. Sessions minted correctly (same; stubSessions records the call)
// 6. Logout revokes session (TestKeycloakIntegration_LogoutRevokesSession)
// 7. JWKS rotation handled (TestKeycloakIntegration_JWKSRotation_RefreshKeysPicksUpNewKey)
//
// All four tests share one Keycloak container (TestMain pattern) so the
// 60-90s container boot is amortized across the matrix.
//
// Build-tag-gated under `integration` so `go test -short ./...` (the
// pre-commit `make verify` gate) never attempts to start Keycloak. Run

//
// Gated behind TWO build tags (`integration` AND `okta_smoke`) so it
// NEVER runs in normal CI — Keycloak is the load-bearing free-tier
// fixture; Okta is a paid dev-tenant smoke test the operator runs by
// hand against the operator's own Okta org. Documented for manual
// verification.
//
// Run via:
//
// export OKTA_ISSUER=https://dev-12345.okta.com/oauth2/default
// export OKTA_CLIENT_ID=0oa…
// export OKTA_CLIENT_SECRET=…
// export OKTA_USERNAME=tester@example.com
// export OKTA_PASSWORD=…
// go test -tags 'integration okta_smoke' -count=1 -timeout 2m \
// ./internal/auth/oidc/...
//
// Pre-reqs in the operator's Okta org:
//
// - One Web Application (OAuth/OIDC) with sign-in redirect URI set to
// http://localhost:8443/auth/oidc/callback (or whatever the test
// operator binds; matches OIDCProvider.RedirectURI).
// - One App Group named `certctl-engineers`, assigned to the user
// above + assigned to the application.
// - The default "groups" claim emitted as a `string-array` (Okta's
// default).
// - "Resource Owner Password" grant ENABLED (Sign-On tab → Grant
// types) — the smoke test uses ROPC to skip the browser login.
// This is for SMOKE TESTING ONLY; production certctl uses the
// auth-code-with-PKCE flow.
//
// What this test exercises:
//
// - Discovery doc fetched against the live Okta tenant.
// - JWKS cached.
// - RefreshKeys returns no error (re-runs the IdP-downgrade-attack
// defense against Okta's advertised signing algs).

// Bundle 2 Phase 14 — session validation benchmarks.
//
// Two paths matter:
//
// BenchmarkSession_SteadyState (target: p99 < 1ms)
// Warm process, signing key already loaded into the in-memory key
// repo, session row already in the in-memory session repo. Measures
// the cost of: parseCookie + signing-key lookup + HMAC-verify +
// session-row lookup + idle/absolute/revoke checks. No network
// round-trips.
//
// BenchmarkSession_ColdProcess (target: p99 < 10ms)
// "First request after server boot" — the underlying repo paths
// are slower because a real Postgres connection is doing index +
// row work the OS has not yet faulted into memory. The benchmark
// simulates this via a configurable per-call repo delay so the
// measurement is bounded above the steady-state path by a known
// amount; the absolute number depends on the operator's Postgres
// setup. The 10ms target accommodates a single round-trip to a
// Postgres on the same host (typical: 1-3ms) plus query-plan-not-
// yet-cached overhead (typical: 1-2ms) plus the Go HMAC verify
// cost (typical: 10-50µs).
//
// The percentile reporting:
// We capture a per-iteration timing into a slice, sort, and report
// p50 / p95 / p99 / max via b.ReportMetric. Go's testing.B does NOT
// surface percentiles natively; the metric labels are explicit so
// the recorded result is unambiguous about which statistic was
// measured.
//
// Run via:
// go test -bench BenchmarkSession_ -benchmem -run='^$' \
// ./internal/auth/session/
//
// The full Phase 14 result table lives at docs/operator/auth-benchmarks.md.
// =============================================================================
// Bench config: Go's default benchmark scaling caps b.N to keep the
// benchmark tractable. For p99 we want at least ~1000 samples but not
// so many that the benchmark takes >10s on a CI runner. We let the
// runtime handle it rather than enforcing a const that lint can't
// trace through to a use site.

// repo + a single active signing key, mints one session row, and
// returns the service + the cookie value the benchmark calls

// Package session — Auth Bundle 2 Phase 6 / session + CSRF middleware.
//
// This file ships the HTTP middleware that wires the post-login session
// machinery into the request path. Three middlewares + one combinator:
//
// 1. SessionMiddleware — reads `certctl_session` cookie, validates
// via SessionService.Validate, populates the actor/role context
// keys (same keys as the API-key path) so downstream handlers
// and RBAC gates see a consistent caller.
//
// 2. CSRFMiddleware — for state-changing methods (POST/PUT/DELETE/
// PATCH), checks `X-CSRF-Token` header against the session row's
// stored hash. API-key actors are EXEMPT (they're not browser-
// driven; CSRF doesn't apply). Returns 403 on mismatch.
//
// 3. ChainAuthSessionThenBearer — the load-bearing chained-auth
// combinator: tries the session cookie first; on miss/invalid,
// falls back to the Bearer-token middleware; if neither
// authenticates, returns 401. Wired in cmd/server/main.go in the
// documented chain position (#6 — Auth, between RateLimit and CSRF).
//
// Bypass list (Category E): the existing public-route allowlist in
// internal/api/router/router.go::AuthExemptRouterRoutes (/health,
// /ready, /api/v1/auth/info, /api/v1/version, /api/v1/auth/bootstrap,
// /auth/oidc/login + callback + back-channel-logout, /auth/logout) is
// preserved by virtue of those routes registering via direct
// r.mux.Handle (they bypass the entire middleware chain). The
// protocol-endpoint allowlist (ACME / SCEP / EST / OCSP / CRL) bypasses
// via the cmd/server/main.go::buildFinalHandler URL-prefix dispatch —
// those routes never reach the auth middleware at all.

// Package session implements the post-login session lifecycle for

// Cookie wire format (`v1.<session_id>.<signing_key_id>.<HMAC>`):
//
// v1.ses-XXXXXXXX.sk-YYYYYYYY.<base64url-no-pad(HMAC-SHA256)>
//
// HMAC INPUT IS LENGTH-PREFIXED to defeat concatenation collisions:
//
// len(session_id) || ":" || session_id || ":" || len(signing_key_id) || ":" || signing_key_id
//
// where len(...) is the ASCII decimal byte-length. Without the length
// prefix, the bare-concatenation form `session_id || signing_key_id`
// would let a forger swap one byte across the boundary — `<a, bc>` and
// `<ab, c>` produce identical HMAC inputs. The length prefix moves the
// boundary into the input itself so the two cases never collide.
//
// HMAC KEY is the 32-byte plaintext of the SessionSigningKey row's
// KeyMaterialEncrypted blob (decrypted via internal/crypto/encryption.go's
// EncryptIfKeySet/DecryptIfKeySet path — same blob format issuer/target
// credentials use). The plaintext is held in memory only during signature
// computation; never logged, never persisted in plaintext form.
//
// VERSION PREFIX is reserved. v1 is the only accepted prefix today.
// A future incompatible upgrade ships as `v2.` and the validator
// rejects unknown prefixes (no fallback attempt — fail closed).
//
// =============================================================================
// CSRF token model:
//
// - Plaintext lives in a JS-readable certctl_csrf cookie (HttpOnly=false
// intentional; the GUI must read it to echo into X-CSRF-Token header).
// - SHA-256 hash of the plaintext lives on the session row (csrf_token_hash).
// - Validation: SHA-256(X-CSRF-Token header) constant-time-compared
// against the session row's stored hash.
// - Rotated by Service.RotateCSRFToken on: login completion, logout,
// any actor-role mutation against this actor, explicit operator
// "rotate CSRF" admin endpoint.
//
// =============================================================================
// Failure semantics:
//
// Validate returns ErrSessionInvalidCookie for any tamper / format /
// missing-key fault. The handler maps to HTTP 401 uniformly (no leak
// of which check failed; specific reason in the audit row). Idle +
// absolute expiry surface as ErrSessionExpiredIdle / ErrSessionExpiredAbsolute
// so the audit row distinguishes; both wire to 401. Revocation is
// ErrSessionRevoked. Signing-key not found / fully purged is
// ErrSigningKeyNotFound. Length-prefix-defeating concatenation collision
// attempts also surface as ErrSessionInvalidCookie because the HMAC
// recomputation fails.
//
// =============================================================================
// Token-leak hygiene:
//
// Cookie values, CSRF token plaintexts, signing-key plaintexts, and the
// HMAC bytes themselves MUST NEVER be logged at any level. The service
// contains zero log statements that include those values; the
// session_id and signing_key_id (both opaque IDs) are the only identifiers
// that ever land in audit rows.
