[Samba] Samba+LDAP: NT_STATUS_UNSUCCESSFUL because of primary group SID mismatch

For me the better way would be, to run serveral openldap servers in master
master replication on your
DC and several BDC. And no headache about anything.
Or just point your BSCs to authenticate against the DCs openldap. But when
your DC is down your authentication is gone.

If you want multiple samba servers to use the same LDAP backend, they
essentially all need to be domain controllers of the same domain.  This is
the supported way to have a single backend shared between multiple servers.

You don't need to ever use the DC function from windows clients, but the
servers need to think they are a DC.
