Phase 14 of the deploy-hardening II master bundle. The procurement- team headline doc + per-connector operator guides for the top 5 most-deployed connectors.

Microsoft IIS Connector — Operator Deep-Dive
Per Phase 14 of the deploy-hardening II master bundle.
Overview
The IIS connector (internal/connector/target/iis/) deploys TLS
certs to Windows IIS servers via PowerShell (Import-PfxCertificate
New-WebBinding+ SNI binding). Pre-deploy snapshot of the existing thumbprint allows rollback if the new binding fails.
Vendor versions tested
- Windows Server 2019 with IIS 10
- Windows Server 2022 with IIS 10
CI runner constraint
Per frozen decision 0.4: Windows containers run only on Windows
hosts. Linux CI runners CAN'T run the IIS sidecar. IIS e2e tests
run on a separate windows-vendor-e2e GitHub Actions matrix job
on windows-latest runners. Operators on Linux-only CI use
//go:build integration && !no_iis to skip.
Per-quirk operator guidance
App-pool recycle (opt-in)
TestVendorEdge_IIS_AppPoolRecycle_OptInForCertChange_E2E
By default, IIS picks up new SSL bindings without app-pool recycle (the binding-edit path is hot). Some sites need recycle to fully reload (e.g., apps that cache cert handles).
Operator action: set AppPoolRecycle: true per-target. The
connector then runs Restart-WebAppPool <pool> after binding update.
SNI multi-binding per site
TestVendorEdge_IIS_SNIMultiBindingPerSite_DeployUpdatesCorrectBinding_E2E
When a site has multiple SNI bindings (different hostnames on the same site), connector targets the binding matching the operator-supplied hostname. Other bindings unchanged.
CCS (Centralized Certificate Store)
TestVendorEdge_IIS_CCSCentralizedCertStoreVariant_DeployToSharedStore_E2E
CCS is the file-based variant where multiple IIS servers share a UNC path of cert files. Connector writes to the shared path; all IIS servers pick it up automatically.
WinRM remote vs local PowerShell
TestVendorEdge_IIS_WinRMRemotePath_vs_LocalPowerShellPath_BothWork_E2E
Two code paths produce equivalent cert installs:
WinRMHost: ""→ local PowerShell (agent runs on the IIS server)WinRMHost: "iis.example"→ remote PowerShell via WinRM
Both rotate the same way. WinRM path requires network reachability to port 5985/5986.
Server 2019 vs 2022 PowerShell compat
TestVendorEdge_IIS_WindowsServer2019_vs_2022_PowerShellCompat_E2E
Import-PfxCertificate + New-WebBinding semantics are stable
across server versions. PowerShell 5.1 (2019) + PowerShell 7.x
(2022) both work.
Friendly name
TestVendorEdge_IIS_FriendlyNameUpdatedOnRotation_E2E
Connector preserves operator-supplied FriendlyName on the cert
across rotation. Useful for IIS GUI identification.
HTTP/2 + ALPN
TestVendorEdge_IIS_HTTP2ALPNPreserved_E2E
IIS h2 negotiation preserved across cert rotation. The
netsh http show sslcert ALPN attribute survives the binding swap.
Binding-type validation
TestVendorEdge_IIS_BindingTypeHttpsValidated_E2E
Connector refuses to deploy to non-https bindings (e.g., http,
net.tcp). Surfaces actionable error.
ARR reverse-proxy
TestVendorEdge_IIS_ARRReverseProxyCertRotation_E2E
Sites using Application Request Routing as reverse proxy: cert rotation does not invalidate ARR routes. The cert-binding edit is independent of the ARR config.
Atomic SNI binding swap
TestVendorEdge_IIS_RemovePreviousBindingOnRotate_E2E
Connector removes the previous SNI binding BEFORE inserting the new one (atomicity at the IIS API level). Prevents brief window where two bindings serve different certs for the same hostname.
Troubleshooting matrix
| Symptom | Test name | Operator action |
|---|---|---|
| Cert installed but app pool serving old cert | AppPoolRecycle_OptInForCertChange_E2E |
set AppPoolRecycle: true |
| Wrong SNI binding updated | SNIMultiBindingPerSite_E2E |
verify hostname selector |
| Permission denied on cert install | n/a | agent must run as administrator |
| WinRM connection failed | WinRMRemotePath_vs_LocalPowerShellPath_E2E |
check WinRM port 5985/5986 reachability |
| h2 negotiation broken post-rotate | HTTP2ALPNPreserved_E2E |
re-run netsh http add sslcert with appid + clientcertnegotiation=enable |
V3-Pro deferrals
- IIS Application Initialization module integration (warm cert cache after rotation).
- Azure Key Vault + IIS integration (operator opt-in).
