  Description 😯

How to reproduce 🕹

1. Login using the user directory adapter
2. Remove the permissions/access in the user directory
3. Login again using the user directory adapter

Expected behavior: login is denied as the permission/access is missing Actual behavior: login is possible, as the browser uses cached responses from previous logins, which were successful Workaround: delete cookies/cache - but might not be suitable
