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.

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.
