[Samba] Questions about a working Samba PDC

[Peter Haight]

Is there anyway to have roaming profiles OFF by default? If I add a user to
a machine, I always have to go and set them to a local profile.

Is there anyway to do groups? When sharing files or printers, I would rather
add a group than each individual user.

I have one Windows XP Pro client and when I do sharing permissions it comes
up with this search interface and it can't find any of the users on the PDC.
Anyone know what's going on with that?
