# Which Problems Are Solved
This PR addresses an issue where the ignoreUnknownUsernames setting was
not being respected in certain scenarios during the login flow.
Specifically:
- When a user was found but rejected due to login settings (e.g.,
disableLoginWithEmail), the system would return a "User not found" error
instead of redirecting to the password page as dictated by
ignoreUnknownUsernames.
- When a user was not found, and the flow fell through the registration
checks (e.g., IDP redirect failed), it would also return "User not
found" without checking ignoreUnknownUsernames.
# How the Problems Are Solved
- Introduced a helper function `handleUserNotFound` in
`apps/login/src/lib/server/loginname.ts` to centralize the logic for
checking ignoreUnknownUsernames and redirecting to the password page.
- Updated the user validation logic to call handleUserNotFound when a
user is found but rejected by policy.
- Updated the registration fallback logic to call handleUserNotFound
instead of directly returning an error.
- Added new test cases in `apps/login/src/lib/server/loginname.test.ts`
to verify the fix and ensure no regressions.
# Additional Changes
- Fixed inconsistency in translation files
