[Samba] Problem with Universal Groups

This is exactly what I am seeing.  I think this should be reopened as a
bug.  I could easily provide all of the diagnostics since I have it set
up like this right now.

The strange thing is, I can get it to work with Domain Global groups,
but not Universal groups which shows the SID properly.  Domain Local
doesn't work at all unless the user is in the same domain as the group.

How do we get this escalated?

Check your winbind group memberships -- I'm willing to bet that your 
winbind will only show group membership for users in the same domain 
as the group.   We are seeing the same mis-behavior here.   Group 
members from other domains are simply not being enumerated by winbind 
as a group member (getent group), even though the other-domain user 
itself is properly listed (getent passwd).

I tried to report this as a bug, but it was closed/reopened as a 
feature request.  Discussion was left that I had to prove that the 
other-domain user can successfully connect to a resource with 
permissions mapped directly to that other-domain user, but fails to 
connect to the same resource when permissions are mapped to a domain 
local group in the local server's domain that contains the 
other-domain user.    (I have yet to create this test-case because of 
unrelated time-constraints...)
