We're not interested in that solution. On one system I may have tcsh shell,
or bash on another.  We have different home paths on different systems as
These systems have local storage, not a SAN providing /home/MYDOM/username
to a user on any system.  I can't imagine how ssh keys would be handled
with one big unified home directory scheme.

I believe we are using it like NT4 style domain with rid user mapping.  AD
is running
on Windows servers.
