I am not a pro at OpenLDAP but do you need to setup the "frontend" database in replication mode? In my setup,
only "cn=config" is set to replicate and that takes care of replication of the "frontend" too such
that any ACL changes in "frontend" of one instance propogate to other instances as well.

Subject: Replication via cn=config
Hi all,
I am setting a pair of multi-master replicated servers (venus and
haumea) using Ubuntu 10.04 and OpenLDAP 2.4.21-0ubuntu5. I am following
the docs at http://www.openldap.org/doc/admin24/replication.html and
when I get to the part for this ldif:
dn: olcDatabase={1}frontend,cn=config
Well, I found the docs (
http://www.openldap.org/doc/admin24/replication.html) a little confusing
(dumb me) and since the only dn I could find to match "dn:
olcDatabase={1}$BACKEND,cn=config" was 'frontend' I assumed that. It
ends up that ${BACKEND} is a new tree and is really the backend (duh!)
and thus the correct is "dn: olcDatabase={1}hdb,cn=config".
Another point that I am still not sure is what to use as $URIx below:
dn: cn=config
changetype: modify
replace: olcServerID
olcServerID: 1 $URI1
olcServerID: 2 $URI2
olcServerID: 3 $URI3
Suppose an hypothetic situation where I want two servers replicating in
a multi-master way, named venus.domain.tld and haumea.domain.tld. Would
I use the same ldif without change for both servers like this:
olcServerID: 1 ldap://haumea.domain.tld
olcServerID: 2 ldap://venus.domain.tld
?
Also, the 'olcSyncRepl' parameter should be set for both on both?
olcSyncRepl: rid=001 provider=$URI1 binddn="cn=config" bindmethod=simple
credentials=secret searchbase="cn=config" type=refreshAndPersist
retry="5 5 300 5" timeout=1
As a suggestion, all configuration examples should have both slapd.conf
and cn=config methods and examples (I am at
http://www.openldap.org/doc/admin24/replication.html.)
Thanks and best regards.
