I have Samba 3.0.24 running on CentOS 4 as a PDC with an LDAP backend. 
When I first set everything up, I could join workstations to the domain 
automatically with the  Windows Network ID Wizard. Now when I try to 
join a workstation I get:

    Your computer could not be joined to the domain because the
    following error has occurred:
    The user name could not be found.

If I add the computer name to the domain manually from the command line 
or with LDAP Account Manager, then go back and join it, it works. But it 
sure would be nice not to have to set up each machine manually. Any
