This is one aspect that isn't really covered in sufficient detail in any
of the currently available documentation, so I have covered it in this
article (which is not quite finished and not in it's final location):
The content of this document is complete, I am currently fixing up the
wording etc, cleaning sample config files and finalising references, so
it should be accurate enough to use. Feedback welcome.
(JHT, I don't think I will have time to cover samba3, but the
replication setup, which constitutes a large part of the document, and
is not covered anywhere else, may be of value for the samba3 docs, and I
think it is complete. Let me know if you want sample configs also).

If you run samba against a slave LDAP server, you will only have
replication traffic from the master to the slave, and password changes.
BTW, you will want samba-2.2.8a for this, since 2.2.8 was the first
release to have working LDAP referrals (allowing password changing when
the local LDAP is a slave, by rebinding to the server returned by the
referral), without which BDC's don't really work.
