LDAP Authentik not working with every user - Snwy - 2024-12-26
Hello everyone,
I'm running an instance of authentik with an LDAP Outpost managing the requests over the Jellyfin LDAP Authentication plugin.
I entered all the values and all the tests can query my instance successfully aswell as return the correct user count for my user and admin filters.
Now when I try to login with two different accounts called Admin & user the results differentiate.
- The admin account processes the login
- The user account returns a "failed username or password"
Logs:
Code:
[15:16:12] [WRN] [29] Jellyfin.Plugin.LDAP_Auth.LdapAuthenticationProviderPlugin: User Manager could not find an user with such ldapUid, this may not be fatal
System.NullReferenceException: Object reference not set to an instance of an object.

[16:14:14] [ERR] [29] Jellyfin.Api.Middleware.ExceptionMiddleware: Error processing request: Invalid username or password entered. URL POST /Users/authenticatebyname.So my question is now: Are there any additional ways that I can try to troubleshoot my error and why the heck the login only works with this account :D

Hi, I am facing the same issue. Except for one user, all of my other users are working perfectly fine.
Code:
[WRN] User Manager could not find an user with such ldapUsername, this may not be fatal System.NullReferenceException: Object reference not set to an instance of an object. at Jellyfin.Plugin.LDAP_Auth.LdapAuthenticationProviderPlugin.Authenticate(String username, String password)RE: LDAP Authentik not working with every user - BaconatorWithFries27 - 2025-07-05
What does Authentik say? Are there any failed logins there? It looks to me like your jellyfin server is unable to find a user with the username "user"
