Despite that RID!=GID, mappings between samba rids and groups must be
there if you want the server to act as a PDC. If there are some GID's
mapped to i.e. RID 512, and these GID is used by another group, then
there will be a conflict.
I had this problem one week ago, when I was trying to give permissions
to a folder. So, choose N GID's to map with samba RID's or change the
group GID of these conflicting groups. Be also areful with UID.
