The problem is not finding the supplementary groups,
but rather establishing them when running under the
uid of that user.  We have to set the secondary groups
for the running process.  This is where the NGROUP_MAX
comes in to play.  The OS won't let a process have
more than NGROUS_MAX gids in its list of secondary
groups.
