From 35ad03196b597ee296468a992985b94ecfe1d887 Mon Sep 17 00:00:00 2001 From: "Beau Beauchamp, WebTigers" Date: Sat, 26 Sep 2026 16:36:55 -0400 Subject: [PATCH] TIGER-242: credential provider owns password WRITES (change/forgot/admin reset) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The pluggable password factor was verify-only: a registered provider (e.g. TigerServer's system credential) authenticated login/unlock, but every password WRITE still landed in the DB user_credential the provider has superseded — so changing or resetting an account owner's password didn't touch the real (OS) password. Make the factor read AND write: - Tiger_Auth_Credential_Adapter_Abstract gains canSetPassword($user) + setPassword($user, $newPassword) (both default false — a verify-only authority like an external IdP stays read-only and reports "managed elsewhere" rather than silently writing an ignored DB row). - New write seam Tiger_Service_Authentication::setPasswordFor($userId, $newPassword): resolves the same provider login()/unlock() use; writes through it when it owns the user, else the default DB path (setPassword + recordSuccess). Fail-safe: unknown user / read-only provider / adapter throw -> false. - Route all three password-write flows through it: Profile_Service_Security::changePassword (self-service), Authentication::resetPassword (forgot-password), and Access_Service_User::save (admin reset). No provider configured -> byte-for- byte the same DB behaviour as before. profile.security.password_change_failed added in all seven locales. Version 1.16.1 -> 1.17.0; CHANGELOG + FEATURES updated. Unit tests extended (read-only default, write-capable adapter).
