You can forget the first two, but because you have two domains (Costumer
& costumerxy), YOU CANNOT USE 'winbind use default domain = yes' with
If you have a user COSTUMER\fred and a user COSTUMERXY\fred, whilst they
are different users, they will both get mapped to CUSTOMER\fred and as
the ID is calculated from the user SID, the ID may change.
