[Samba] kerberos and Win2003AD problems

[treklor]

Hi!

I've upgraded Samba-3.0.4 to 3.0.6 and now I can map shares but not 
read/write/update any folders/files on the samba share.
When I ran 3.0.4 everything worked fine, I even used the ACL settings
on files and folders and that worked too.
My problem then was when the kerberos ticket had expired, everything
stopped working, so I downloaded the the 3.0.6 version and installed it
hoping that this would resolve my problem with updating tickets.
No such luck. :-( Instead I got new problems, see errormessage. :-(

My Question: How do I configure Samba 3.0.6 and kerberos to work with 
Windows 2003 AD as a memberserver?
