sorry, I need to resurrect this thread and this project.  I would really 
like to get this working on ubuntu server.  Brief is in email below, 
more details in the bug report

What other troubleshooting steps / logging can I do to try and track 
down the issue.  I can set up another server, clean, and the same issue 
happens with it

brief: gpupdate when run during login, fails with unable to get SID 
token. The same command run interactively runs with no issues.

The SID is for the user (Peter) and the user can login over ssh.  I can 
repost all the logs and configs here if needed.

samba built from git master branch using bootstrap configure flags. 
tested both with built in heimdal and mit krb.

after a bunch of testing with David Mulder, recommendation was to create 
a bug report: https://bugzilla.samba.org/show_bug.cgi?id=15225

What other troubleshooting steps / logging can I do to try and track 
down the issue.
