questions about openldap replication

Hi All,

i've read through the replication section of the admin guide, but i'm still not clear on the ff:

1. For push-type setups, do i really need to set up a sync proxy? the docs seem to imply this is necessary only if there are firewall restrictions, yet i haven't seen any examples of a push setup w/o a proxy.

2. Is it possible to set up a push delta-syncrepl scheme?

3. In a syncrepl/delta-syncrepl push setup, how does the master know where the replicas are?

Things were a bit simpler with slurpd...ah, progress B)
