I am however interested in going the LDAP route mainly for the forward compatability reason stated by Jeff. Is there anything special I need to do on the DC for the LDAP authentication to work?

No, but you'll have to generate UIDs and GIDs for all AD users and groups....

That is the one thing that has stopped me from using AD LDAP for
user/group management.

You could use winbind to create a NIS map (sans passwords) and have
Linux/Mac clients authenticate with NIS+Kerberos.

That RID map feature of samba is great.
