Problems Authenticating NT Users Agains Domain

Dear all,

We have set up an HP UX 11 machine running samba 2.0.6.
The samba machine is member of the domain tflxxx and should authenticate
users again the domain and not against the local users.

The samba machine should expose the directory /data_share to a NT user group
called ggsamba (which is defined as global group on the NT PDC). The
username map attribute of the global section contains a mapping file, which
I understoud, should map unix accounts against NT accounts. In my case the
unix group unixgroup to  ggsamba.

In my case the authentication fails somehow.

Does someone has a clue how to solve the problem or where I missed
As far as I understodd the mapping should surround the need to setup the
users twice?

Here is the smb.conf:
# Samba config file created using SWAT
# from (
# Date: 2000/10/27 13:03:35

# Global parameters
	workgroup = TFLxxx
	netbios name = TFLSAMBA
	server string = Samba Server
	security = DOMAIN
	encrypt passwords = Yes
	password server = tflNTPDC
	username map = /opt/samba/
	log file = /var/opt/samba/log.%m
	max log size = 2000
	domain groups = ggsamba
	local master = No
	read only = No
	short preserve case = No
	dos filetime resolution = Yes

	comment = data_share
	path = /data_share
	valid users = @unixgroup

The file /opt/samba/ 
unixgroup = ggsamba

The log for my machine contains the following
[2000/10/27 12:50:49, 0] lib/util_sec.c:(52)
  Failed to set uid privileges to (-1,-2) now set to (0,0)
[2000/10/27 12:50:49, 0] lib/util.c:(2456)
  PANIC: failed to set uid

Thanks in advance.

Kind regards,
