unix file permission manipulation.
let's say that you want to move some files from one domain to another, and
you are going to shut down the first domain and bring back a second
domain. this presents a problem: your SIDs are going to become invalid
(as they are in the first domain).
so, what you do is you create a "local group", and you make all the
"domain users" and "domain groups" of the about-to-be-retired domain a
_member_ of that local group.
you then add access rights of this "local group" to all the files you're
going to move to the new domain, prior to taking down the old domain.
if we are going to be a PDC, then we need to be able to allow users the
right to use "local groups", a.k.a "aliases", and add such permissions to
files. which means that administrators need to be able to create them,
which i envisage should be provided by something identical in
functionality to "map groupname", and i suggest that we call it "map
