this module provides nt user / nt rid lookup functions.
users, local groups, domain groups.
no unix / samba functions should be called in this module:
it should purely provide a gateway to the password database API,
the local group database API or the domain group database API,
but first checking built-in rids.
did i say rids? oops, what about "S-1-1" the "Everyone" group
and other such well-known sids...
speed is not of the essence: no particular optimisation is in place.
