Apparently that's not true.  Unqualified names are passed along with a
realm.  From what I can tell in testing a whole range of variations of
defaultdomain, virtdomains, servername and the like, it seems it always
passes a realm onto the SQL select query.

Is it not possible to pass an unqualified name?  What configuration would
allow it?
