[Samba] Terminal server login problem

Hi all,

I have a strange problem with the combination of Win2k3 and Samba. The 
samba server is configured as a PDC, the terminal server as a member of 
the domain. Logging in from the terminal server console with a domain 
userid works; logging in from a terminal server session from the same 
machine fails with the message: "The system can not log you on due to 
the following error: The specified domain either does not exist or could 
not be contacted.". Logging in to local accounts works. Mapping shares 
to the Samba server also works.
I've googled and found some references to mismatched signing and 
encryption settings, but I've tried all combinations to no avail 
(including the SignOrSeal registry patch).

Following are two level 10 logs, one OK login from the console and one 
failed login from a terminal server session. (both very long ...)

Versions: Win2K3 SP1, 15 TS CAL's (also tested without the service pack; 
same results).
Samba: Version 3.0.14a-Debian (on a freshly installed Debian Sarge box).

The configuration file:
        workgroup = SAHIN
        server string = %h server (Samba %v)
        obey pam restrictions = Yes
        passdb backend = tdbsam, guest

        passwd program = /usr/bin/passwd %u
        passwd chat = *Enter\snew\sUNIX\spassword:* %n\n

        write list = root, @NTAdmin

        comment = Logon scripts
        path = /home/netlogon
        write list = @NTAdmin,root
