we have a problem: resolution of "Primary Group RID" which we assumed
would only be a domain group rid.  it can also be a local group rid,
which causes us problems in attempting to turn a unix gid into the
correct rid (domain group or local group).

sooo.... the fix is _in_ there, we just can't use it because it causes
link / knock-on problems in nmbd.
