AFP mount + Chown/Chgrp respecting

Hello all...

Does anyone know how to make an AFP mount of home directories (/Volumes/users off of another server) so that any users doing an ssh login retain write permission to their individual folders, read-write permissions to folders chowned to appropriate group... and so that newly created files are done so with their own user name?

Thanks for any suggestions.

p.s. I am able to mount as a specific user, but any simultaneously logged-in user is not able to write into their own folder then (as the mount is done in the name of the other user). Mounting as 'admin' doesn't help. Mounting as 'root' isn't available (I can sudo mount... but not login as root.. but sudoing the mount doesn't help either ).
