## Problem Enabling `Disable Phone Login` (or `Disable Email Login`) in the login policy caused some users to receive "User not found in the system" even when logging in with a valid, non-phone identifier. Users whose preferred login name looked like an email address (e.g. `[email protected]` in an org-scoped context) were rejected incorrectly. Toggling the setting back off immediately restored login for those users. Fixes #11518 ## Root Cause In `loginname.ts` and `password.ts`, the post-lookup guard that enforces the disable-phone/email restriction used `||` instead of `&&`: ```ts // BEFORE (buggy): rejects if preferredLoginName doesn't match OR email doesn't match // → any user whose preferredLoginName ≠ raw email is rejected if (user.preferredLoginName !== concatLoginname || humanUser?.email?.email !== command.loginName) { return preventUserEnumeration(...); } // AFTER (correct): rejects only if preferredLoginName doesn't match AND email doesn't match // → user passes through if they matched by either their preferred login name or their email if (user.preferredLoginName !== concatLoginname && humanUser?.email?.email !== command.loginName) { return preventUserEnumeration(...); } ``` The intent is to allow the user through if they matched by their preferred login name **or** by the still-permitted identifier. By De Morgan's law, the rejection condition must be `¬A ∧ ¬B`, not `¬A ∨ ¬B`. ## Changes - **`loginname.ts`**: fixed 2 `||` → `&&` in the `disableLoginWithEmail` and `disableLoginWithPhone` guards - **`password.ts`**: fixed 4 `||` → `&&` across the same guards in both `resetPassword` and `sendPassword` - **`loginname.test.ts`**: added two regression tests: - `disableLoginWithPhone=true`, user logs in with their email-format preferred login name → must succeed (was broken) - `disableLoginWithPhone=true`, user logs in with their actual phone number → must be blocked (feature still works) ## Testing All 654 unit tests pass.
