[Samba] Group mapping giving incorrect GIDs

That's true - but if you've only got a handful of mappings I wouldn't
have thought it'd be too bad.

Well we've only got the one domain, and within that I'm only worried
about a handful of GIDs.  To be honest, I'd be happy with a method that
would map about 20 NT groups to equivalent UNIX groups, and map
anything and everything else to the "nobody" group.

It looks like perhaps not running winbindd at all might be something to
look into - I'll try that now.

Cheers,
Adam.
