[Samba] XP SP2 - winlogon.exe crashes

[Geoff Scott]

==============
The problem:
==============
I am in the testing stages of implementing a Samba domain.
My user is logging on to a standard win xp SP2 desktop, with the samba pdc,
supplying the credentials. The logon screen disappears and an "SAS window:
winlogon.exe - Application Error" box pops up on the Win XP screen. If I
click OK the machine reboots.

My user can log onto the Debian Sarge server using ssh fine. My other users
in the same ldap Users container can log onto the open-xchange part of this
server fine.

==============================
My attempts at problem solving
==============================
reset the users password
removed the XP machine from the domain and added it again.
added the " use sendfile = no" directive to smb.conf
shutdown the firewalls on both the XP machine and the server

==============================
technical details
==============================
Samba version: Version 3.0.10-Debian
Linux flavour: debian Sarge
XP version SP2 
Ldap with bdb backend (users can log on with other applications)

=============
The questions
=============
Can anyone point me in the direction of docs that I can use to fix this?
Can anyone decrypt the content of the error message from the logs below and
point me in the right direction?
