samba - Mar 2009 - samba AD integration

I was looking at:
http://wiki.samba.org/index.php/Samba_&_Active_Directory - the
Configuring Windows part says: "I am still working on that ... " -
could someone point me to a documentation on the Windows 2003 end of
things? I have done the Linux end and now need to do the Windows part
(groups, users, permissions etc.)

Thanks.
