[Samba] NT user token: (NULL) what does this mean?

[Michael Andrewjeski]

I've just noticed this in the log file for a user that cannot connect. It simply repeats over and over 
in the log. What the user sees is that he maps to the share, then gets a message "access denied" 
He can however connect to any subdirectory beneath the share. Weird.

The setup is samba 3.0.4 on Redhat compiled with windbind as a member server 
Connecting to a Win2k domain using rpc, smb.conf sent upon request.   

Thanks Mike.
