I've been able to use SMB authentication against an AD just by filling 
in the entries in system-config-authentication.  I'm not sure if  that 
requires any compatibility settings on the AD side or not - it just 
worked for me so I didn't ask questions.   The down side is that you do 
have to add the users and maintain groups on the linux side which isn't 
too difficult if they don't change a lot, just
adduser -u uid -g gid login_name
with the same values on all the boxes and copy changes to /etc/group 
around. The up side is that you can control which users have access 
separately and only have to deal with passwords for users that aren't in 
AD - and you don't have to ask permission to join the linux boxes to the 
domain.

Winbind can automatically create users from AD, but you have to join the 
domain and I'm not sure what you have to do to coordinate the uid 
mapping across machines so NFS shares work.
