Nothing has changed as far as Samba is concerned.  The rules for updating
the LDAP databases are now governed by the standard rules governing
multi-master replication for the LDAP software.

The machine will contact the PDC and the PDC will contact the LDAP server
specified in its smb.conf file.

The LDAP software will take it from that point.

Take a look at chapter 5 in the Official Samba Howto.

Pay special attention to the section entitled "LDAP Configuration Notes".
