I can't help with the tdb method but your smb.conf is good to go for the
ad backend. To use it, you will have to add the rfc2307 attributes to
the 2008 box somehow. You can add e.g. uidNumber number to users under
the Unix tab on ADUC on your existing DC.

Another good way to get the attributes would be to join a Samba4 machine
to the domain as another DC. It's then a simple matter to wrap a script
around ldbmodify to dump the attributes into AD from that box and let
replication do the rest.

Do you have a lot of users?
