User/Group synchronization

I’m facing an issue in Univention where an error occurs during user and group synchronization using the connector-ad. Initially, everything seems fine, but upon generating an LDIF file out of the Univention-LDAP, I’ve noticed that for groups, the BASE-DN is entirely in lowercase (for example, “KVVUsers” becomes “kvvusers”).
This leads to an error in the OX Appsuite, indicating that users are not correctly associated with specific groups.
If I delete the group association in UNivnetion LDAP and put it back in, everything is fine.

Some ideas?
