Nice, that fixed the creation of sambaIdmapEntry objects in ou=IdMap
That definitely needs to make its way into the howto.

until i added winbind to the nsswitch.conf file.

'wbinfo -u' :
'Error looking up domain users'
'wbinfo -g' :
BUILTIN\print operators
BUILTIN\backup operators
BUILTIN\replicator
BUILTIN\account operators
BUILTIN\administrators
BUILTIN\guests
BUILTIN\server operators
BUILTIN\users
'getent passwd DOMB\\username' however works and pulls up the correct
idmap info.
'wbinfo -m' :
BUILTIN
DOMB
'wbinfo --sequence' :
BUILTIN : 1
DOMB : DISCONNECTED
DOMA : 1
The problem still exists where a user has to access a share on the pdc
before any of the member servers will stop popping up the password dialog.
