When we converted our PDC to 3.0 we first just upgraded Samba (bieng careful to
migrate the SID of course) and used ldapsam_compat, then after a week of
successful operation we converted the Dit using the provided scripts and
switched to ldapsam. This provides a low-risk and almost painless upgrade
route. The ldapsam provides lots of advantages over ldapsam_compat, so it is
worth it to move.
