Jellyfin 10.9-unstable: No LDAP Login

[pixel24]

Hello everyone,

We have a Univention server here (UCS 5.0.7) configured as ADS, providing users/groups. My JF 10.8.13 is connected to it, and LDAP user login works. Now, I've installed a test VM with Debian 12.5 and JF 10.9-unstable. However, LDAP login doesn't work anymore. I configured the LDAP connection in 10.9 as follows, and all tests in the plugin configuration return correct values.

Code:

LDAP Server:                    srv01.lan.example.de
LDAP Port:                      7636
Secure LDAP:                    [x]
StartTLS:                      [ ]

Skip SSL/TLS Verification:      [x]
Allow Password Change:          [ ]

LDAP Bind User:                uid=ldapbind,cn=users,dc=lan,dc=example,dc=de
LDAP Bind User Password:        secret

LDAP Base DN for searches:      dc=lan,dc=example,dc=de


-> Save und test LDAP-Server-Settings -> Connect (Success); Bind (Success); Base Search (Found 873 Entities)



LDAP Search Filter:            (memberOf=cn=JellyfinUsers,cn=groups,dc=lan,dc=example,dc=de)
LDAP Search Attributes:        uid, cn, mail, displayName
LDAP Uid Attribute:            uid
LDAP Username Attribute:        uid
LDAP Password Attribute:        userPassword
LDAP Admin Base DN:            (cn=Administrators,cn=Builtin,dc=lan,dc=example,dc=de)
LDAP Admin Filter:              (&(objectClass=posixAccount)(|(memberOf=cn=Domain Admins,cn=groups,dc=lan,dc=example,dc=de)(memberOf=cn=Administrators,cn=Builtin,dc=lan,dc=example,dc=de)))
Enable Admin Filter 'memberUid' mode: [x]

-> Test and save LDAP-Filter-Settings -> Found 4 user(s), 2 admin(s), Warning: Not all Admins are Users


Test Login Name:                s.example

-> Sace Search Attribute Settings and Query User -> Found user: uid=s.example,cn=users,dc=lan,dc=example,dc=de


Enable User Creation:          [x]

Unfortunately, the Jellyfin log file provides little insight into the reasons for the failure:

Code:
