Hi, apparently all of a sudden a member server running Debian Buster with Winbind in an Active Directory environment started to map the domain users in a weird way.
Many users and group seem to have two or more names, but the same id. But this is a problem when users try to access, because it seems they are recognized with their right name, but the server seems instead to expect a different wrong name. I tried to delete /var/cache/samba/netsamlogon_cache.tdb and restart winbind, with no improvements. What the hell could have happened? Best regards.
