Thanks for the tip, I didn't know about the subordinate keyword even though
it's clearly documented in the slapd.conf manpage. Unfortunately, for now, 
I'm tied up with openldap-2.0.x for this.

I'm a little wary about replication myself for the purposes of pushing data to
remote sites (and not just a local backup server), but I understand openldap-2.2 has
many advances in the replication area. I'll keep an eye on its development and start to
test it as soon as possible.

Thanks for the tips.
