[]  ...
So, I'm inviting suggestions for fixing this.  There
is some simple, elegant way to solve this problem
isn't there ?

How do NT servers handle this now ?
[]  Currently our servers forced to support mapping of NT users to UID/GIDs
(which by the way usually a big security problem for unix clients).

[] I would like to see something more open than 32 bit UNIX UID/GID scheme -
probably some kind of 'printable' identities. Also it would be useful to know
what is the identity (or possible set of identities) of files that are created for the 
current authenticated user. Note: these identities could be different from those
returned during authentication. If Clients (a.k.a. Redirectors) whish to provide
additional mapping to satisfy requirements of operating systems and applications,
they certainly can do this. 

One of the noble goals in transition into NFS-4 could be substitution 
of the UNIX-centered philosophy of NFS for SERVER-centered philosophy. 
We probably should admit that there are other file systems around and the 
new protocol should be convenient and non-restrictive for all homogeneous
Client-Server combinations.
