Problem with lookup_name

Well, when I am trying to do this I am logged in as a domain administrator.

However, I am pretty sure that as long as a user already has "full control"
perms on a file or directory, they can alter the perms to allow someone else

The clincher that this is not the problem is that I can set permissions if
the person I am trying to give permissions to has logged on to the win2k
machien in the past.

On Win2K you can't assign permissions if you don't have
administrative rights LOCALLY. This is the only reason I
see for trying to get authenticated through winbind.
