samba - May 2004 - Crazy User Entry in W2k, Samba 3.0.2a-Debian, UID-SID Mapping damaged ?

Hi, 

i'am testing to setup a plain Samba PDC Domain.

Now i habe the strange Problem, that the User Entry in Windows Security
Dialog show different User that the underlying Samba Filesystem (XFS).

In W2k is a User ACL called TKH\games, but such user isn't allow to do
anything in the Filesystem, so what's going on ?

Here some more Infos:

debian:/var/log/samba# smbd -V

debian:/var/log/samba# ls -l /var/samba/ | grep test

debian:/var/log/samba# getfacl /var/samba/test/

debian:/var/log/samba# grep games /etc/passwd
games:x:5:100:games:/usr/games:/bin/sh

debian:/var/log/samba# net getlocalsid
SID for domain DEBIAN is: S-1-5-21-521418629-2349234423-895658885

--> Why is the Domain not TKH (which is configured in smb.conf ?)

--> looks strange too !?

Windows 2000 Service Pack 4

I can't change the User Rigth's in Windows Security Dialog too (after
reopen the Securitydialog  the Right's resets everytime back to
Original).
Can you point me to the source of the Problem ?

I think something going completly wrong.
Can anybody help me ?

Thank You
Thomas
