I think that anyone using this would expect it would take the first
one returned.  The same that happens right now in a "normal" system.
The same name that 'ls -l' would return.  We don't worry that 'ls -l'
might be mapping a name that might not be unique and shouldn't here
either.

I realize that 'nscd' breaks that long standing assumption that order
matters by returning one randomly.  I consider that a bug in nscd.
