[Samba] domain trust relationship with AD 2003 and user profile and home directory problems

[Lukasz Zalewski]

Hi!
We have a PDC for EEKS domain, running samba 3.2.0 FC9 64 bit, with the 
following trust relationships:
one way trust where EEKS trusts ITL domain which is running Samba 3.0.30 
FC8 64 bit
two way trust between EEKS and ADEEKS domain which is running Windows 
Server 2003.
Now for a given Windows XP SP2 workstation in EEEKS domain:
1. User logs onto ITL domain through the trust relationship and gets the 
appropriate profile and home directory
2. User logs onto EEKS domain and also gets the appropriate profile and 
home directory
3. User logs onto ADEEKS domain but does not get home directory nor a 
profile.
I have been looking at the logs and found the following entries:

which seems to suggest that the necessary information is equal to the 
empty string (That information does exist in AD). Is this happening due 
to the misconfiguration of samba, or AD? Can this be done at all? If so 
what do i need to change? If this cannot be change can i override the 
above settings through samba?
I have run out of ideas so any suggestions would be much appreciated
