hmmm, i see the light.  you'd have to ignore that capability in HP/UX ACLs
or map to every single group manually or implicitly.  this ACL would
certainly have...

ummm.... what _exactly_ is meant by "user x has read/write access when in
group Y"?????? you mean, the HP/UX designers intended users to be moved
from group to group, and ACLs to change meaning / take this into
