[Samba] With a PDC, is homes mapping automatic?

[MargoAndTodd]

Hi All,

I am upgrading my Samba server to a PDC from a work
group server.

Question: when a client computer joins as a domain
member, is his "My Documents" automatically mapped
to his [homes} directory?  Or, is it something
I do optionally?  (In my test bed, My Documents
is getting mapped to his "C:\Documents and Settings...")

Many thanks,
-T
