I have tried this, but of course i did it as the users $HOME
directory. The reason we do it this way is because we use that file
server to then back up all environmental files and user data. This is
currently working, and has been for years, on other hardware ... we
just purchased the HP at the end of last year, and silly me thought i
would just migrate everything over like i have time and time again :(

At this point i supposed i can try anything, this device is not in

I basically achieved this same thing by doing an 'adduser newuser' and
providing it a password which then created the $HOME directory on the
NFS mount, and then attempting to login to Gnome or KDE as that user
to no avail - same error

Thanks for the suggestions on some other things to try.
