Once winbind assigns a uid/gid to a user it seems impossible to clear it. I’ve even tried deleting and reinstalling the packages samba, samba-client, and samba-winbind, removing /etc/samba and /var/lib/samba. When winbind comes back up it still has the old uid/gid assignments.
How can I get winbind to forget the old uid/gid assignments so I can set them up the way I want?
