ConfirmablePasswordController checked the local hash and nothing else:
Auth::guard('web')->validate(['email' => ..., 'password' => ...])
An account provisioned from a directory has no local password. It holds a
Str::password(64) generated at provisioning time that nobody has ever
seen, and the application knows this -- LdapAuthenticator::isDirectoryAccount()
is the question, and the sign-in form asks it before deciding what to
check. This screen did not, so it refused those accounts the only password
they have.
That is not a cosmetic refusal. `password.confirm` stands in front of
enrolling in two-factor, so a directory-provisioned client could not enrol
at all. Set TwoFactorEnforcement to `clients` or `all` and EnforceTwoFactor
redirects every request they make to two-factor.show -- a screen whose
"enable" button leads to a door they cannot open. PR #1708 fixed the
routing half of that ("Let an enforced user reach the far side of the
confirm-password screen"); this is the credential half.
The rule now lives in one place. PasswordVerification is the sibling of
SignIn on the other side of the line SignIn draws -- SignIn is everything
after a credential checks out, this is the one question asked before it --
and it exists for the reason SignIn gives for existing: "the way they get
broken is by being written twice". LoginRequest keeps its ordering, its
provisioning and its rate limiting, and delegates the check itself.
Behaviour preserved exactly on the sign-in path: local hash first so an
account that answers locally generates no directory traffic, directory
only for accounts whose credentials live there, the stale-hash re-hash on
the local branch only, and the ldap_dn stamp on the directory branch. All
23 existing LDAP sign-in tests pass unchanged.
One thing this closes on the way past. Because the old check went straight
to the local hash, a directory account's placeholder *would* have confirmed
if anybody ever learned it -- a door the sign-in form does not have, since
it skips the local branch for those accounts. It now behaves the same on
both screens; there is a test.
**What this does not fix, and should be read as a limitation.** Accounts
provisioned by a social provider are in the same position -- a random local
password nobody holds -- and they are not directory accounts, so this
changes nothing for them. Their route to a local password is the password
reset, which #1748 made work end to end by moving auth_source to Local when
the reset completes. A social account that has never done that still cannot
confirm a password, and so still cannot enrol in two-factor.
Tests: three fail against the unfixed pair, including the placeholder case
above. Two more pin what must not change -- a wrong directory password is
still refused, and a local account with LDAP switched on still confirms
against its own hash.
Two accounts reach the same reset with opposite needs, and it treated
both as "write a hash and hope".
A provider-created account is told, on the Connected accounts screen, to
"set a password first, then disconnect Google" -- and doing it changed
nothing, because nothing ever set auth_source back to Local.
AccountConversion is the only writer, and that is an administrator. So the
screen went on asking for something that had already been done, and the
person could not release their last provider without help.
AuthSource states the rule that closes this: `social` means the account
came into existence without anybody choosing a password, and, in as many
words, "a social account may later set a real password". A reset by
emailed token is where somebody does. The screen's has_local_password prop
is literally auth_source === Local, so the write is what completes the
sentence it prints.
A directory account is the opposite case and gets the opposite answer.
isDirectoryAccount() means the local hash is not consulted at all, so the
reset reported success and left the person with a password that cannot
sign them in -- including when the directory it points at is gone, which
is exactly when somebody reaches for a reset. It is refused now, with the
reason, and nothing about the account moves: taking one off its directory
is an administrator's decision through AccountConversion, not a side
effect of a reset.
The refusal sits where the token has already been validated, not where the
link is asked for. That endpoint answers "A reset link will be sent if the
account exists" to everybody on purpose, and refusing there would tell a
stranger both that an address is an account and how it signs in. Throwing
before the write also leaves the token unspent, since PasswordBroker
deletes it after the callback returns.
