First of all, slurpd allows you some partial replication.
Then, in OpenLDAP 2.4 (currently in alpha) you'll find push replication
via syncrepl by means of a hidden proxy database, so that the consumer is
a proxy hidden in the producer that pulls changes out of the producer and
pushes them into the consumer.
For a quick'n'dirty approach, you should look into the "attrs=" parameter
of the "replica" statement. For a long term, yet experimental solution
you should look into test045 and test048 in HEAD/2.4alpha code.
