There are a few lines that are duplicated in each smb.conf.
I take it that you only use the PDC for authentication and don't let the
users login.
It has been sometime since I setup and used a linux client with a PDC,
but I don't actually remember having all those passwd & script lines in
the client smb.conf.
Do the users exist as unix users on both machines ?
