Question Domain Controller Authentication under Samba not working!!


Hi,

I have recently been transferring a network infrastructure from Server 2003 to CentOS and have setup DNS, DHCP, Samba.
I have nearly completed implementing a PDC under Samba and everything was going smoothly. The hitch I'm having is logging on from an XP client to the DC. It allows the logon to happen but gives me a temporary profile only, showing two errors at logon about not being able to load a roaming/local profile.

I have looked at the log file:
[2009/09/17 13:38:27, 0] auth/auth_util.c:create_builtin_administrators(844)
create_builtin_administrators: Failed to create Administrators
[2009/09/17 13:38:27, 2] auth/auth_util.c:create_local_nt_token(966)
create_local_nt_token: Failed to create BUILTIN\Administrators group!
[2009/09/17 13:38:27, 0] auth/auth_util.c:create_builtin_users(810)
create_builtin_users: Failed to create Users

As far as I know, the account database is correct on the Samba side. I know that for a first logon to the domain, a root account must be used, I have given this a try as well as several other user accounts. The computer account has a trust relationship with the domain. I'm guessing that a problem may exist in the permission side of things but have really only been plucking at straws to try and get it working.

I don't have too much Linux knowledge and would really appreciate your help!

Cheers,

I think you might have to tell Samba about the user account XP is going to connect with.
On the Linux box, Try:

smbpasswd -a <user account XP is trying to access PDC with>

I will give that a try tomorrow when I go into work.

What about the root account on Samba that I need to join the domain with first? When I join with a user on the XP client, the user is an account in Samba, not on the XP machine. So shouldn't it not matter??

And if I do need to join say the Administrator account, do I enter, 'BUILTIN\Administrator' with 'smbpasswd -a' or just 'Administrator'?

Thanks for your help

In this case it looks like it's trying to find information from the PDC about the local groups "Administrators" and "Users". You could try creating those two groups manually, or set Samba up to automatically create groups it doesn't know about using something like this in smb.conf:
Quote:
add group script = /usr/sbin/groupadd "%g"
(or whatever is appropriate for your flavor of Linux)

As far as adding users via smbpasswd, you don't need to specify a domain for that command.
