LDAP meta directory
Sometimes you need to combine two or more LDAP directories with same suffixes to one directory or you just need to have a proxy. My first attempts to combine two OpenLDAP directories was to make replication from two different sources. This solution however has some disadvantages. First of all: to have syncprov replication your environment must be uniform, this means all source servers and proxy needs to be OpenLDAP. Second: I observed that this is not so stable, because of mentioned earlier issues with OpenLDAP replication.
