Indeed, though not in the details, but that may not be necessary depending
on what this means:


    - Revamp Solaris ACL implementation to more closely work like
      POSIX ACLs are supposed to work. Finally implement a CLASS_OBJ 
emulation.
      Update getfacl(1)/setfacl(1) accordingly.

Not very specific, but may have addressed any issues in that area.

The part that looks a bit more "hairy" are the auto-RID-UID mappings
and how those will work with existing UID/RID mappings coming from
a samba server...  Specifically, will cygwin support UID's > 32 bit?

I found to cleanly separate various login & service types into contiguous
blocks was good to multiply by large numbers.  I'm thinking cygwin already
supports the longer numbers or things like 'TRUSTED INSTALLER' wouldn't show
with the right owner or be changeable in cygwin...

Thanks for the reply...
