[Samba] roaming user profiles do not transfer all settings

[J.P. Trosclair]

The safe thing to do so that you can be sure of the behavior would be setup
a test user on the PDC (clean account, do not copy a profile or anything of
the like), login with the new user account to a windows workstation that is
a member of the domain and configure his profile (change the wallpaper, the
fonts, whatever) and log out and then log in from workstation #2 and see if
the changes persist. If this works, then you know the problems or unexpected
behavior you're currently experiencing is a result of the existing profile
you copied and are testing with.

Note, you can (and probably will) experience problems when using different
versions of windows with the same profile.
