That's exactly what I'm doing here. Almost every MTA and the cyrus servers
have their own LDAP replica. I had some problems years ago when the
central and only LDAP Master hung from time to time. Now, every service is
configured to use it's local replica and another one as fallback.
Enlarging the cachesizes in OpenLDAP has also helped alot.
