OpenLDAP as master of other vendors' directory servers?

["Phil Durbin" <pdurbin@berklee.edu>]

We're thinking about using OpenLDAP as our "master" or primary 
directory server.  However, like a lot of folks, we need to run other 
vendors' directory servers as well.

My primary question is if anyone is using OpenLDAP as a master and 
replicating/synchronizing the data to a Netscape/iPlanet/Sun ONE/Sun 
Java System Directory Server.  Down the road, we may also need to 
synchronize with Active Directory and Oracle Internet Directory.

I've heard of people using Sun ONE Directory as a master and 
replicating data to Active Directory.  And Oracle says its directory 
server can be a spoke on another vendor's hub.  But are people using 
OpenLDAP as the hub?

I get the impression from this lists' archives that this is going to 
require some custom programming.  Are we talking about scripts to dump 
and import LDIF files?  Cooking something up using perl-ldap, JNDI, or 
JLDAP?  Are there ready-made scripts or other tools available to make 
synchronizing data from OpenLDAP to Sun ONE as painless as possible?
