[Samba] sharing users home dirs for Win2003 and linux

[Ze'ev Maor]

I've setup a linux box with winbind as a member in Win2003 AD and
everything works fine.
I want to share the Win2003 users home dirs with the linux box, i.e.
when a user logs into the linux box, after he's authenticated through
winbind, he should have his home dir from the Windows box, how can I do
that??
Obviously I have to use CIFS to mount the dirs, but how do I maintain
file and dirs ownerships and permissions??
