That's probably nothing to do with Samba, and more with me trying
(and failing) to be more efficient. I've got 90% of a rewrite here
that should simplify things, but I'll now have to put it on hold

Looks like it... or that's the only time the groups are reliable.

But the issue is more that it looks like the groups can only
accurately be known by enumerating the list of sids returned after
a successful login. Which throws the xlat into a right mess.

But I need to look at it more to be sure.
