I'm using a member server joined to my primary domain. I'm using winbind because I have a trusted domain. both pdc and member server has idmap uid = 80000-90000 idmap gid = 80000-90000 idmap backend = ldap:ldap://my.pcd member server has security=domain password server = * (and no passdb line) nsswitch.conf on the member is passwd: compat winbind group: compat winbind shadow: compat Everything works great. Mappings are stored in idmap and I have consistent uids for the trusted domain on both the pdc and the member server. However mappings for the primary domain (that the server is a member of) on the member server are diifferent from the pdc of that domain because it creates new mappings in idmap in ldap. That means that all member servers will have consistent mappings for the primary domain and all bdcs will have consistent mappings but the 2 sets of mappings will not be the same. Is there any way I can make the 2 sets the same? Samba is 3.4.7.
