samba - May 2009 - user cannot logon to domain although log says "auth succeeded"

I have a very strange problem and I'm doomed. In a samba-domain with
XP-clients certain users cannot logon to some computers.

The user tries to logon but *immediately* gets the message "you cant get
logged on. please check username and domain and retype your password"
(translated from german) on the XP-machine.

In the samba-logs (Loglevel=2) it says:

[2009/05/19 16:47:16,  2] lib/access.c:check_access(406)
  Allowed connection from  (192.168.1.77)
[2009/05/19 16:47:16,  2] smbd/reply.c:reply_special(492)
  netbios connect: name1=SERVER          name2=VOEV12         
[2009/05/19 16:47:16,  2] smbd/reply.c:reply_special(499)
  netbios connect: local=server remote=voev12, name type = 0

[2009/05/19 16:47:26,  2] auth/auth.c:check_ntlm_password(308)
  check_ntlm_password:  authentication for user [ingrid] -> [ingrid] ->
[ingrid] succeeded


I used samba 3.0.28 that comes with ubuntu 8.10 but now I compiled recent 3.3.4
and have the same problem, so its either a problem on WinXP-side or in the
config itself.

A more detailed log at Loglevel=15 can be viewed at :

I'm kind of desperate here and I'm really looking forward for any
hint/tip/help ...

thnx,
peter

I never understand why people cut log files. There is NO
indication whatsoever about any failure, but a lot of
indication that parts of the log file were cut off.
