One more question, this time on the chaining overlay.
“What is chaining? It indicates the capability of a DSA to follow referrals on behalf of the client, so that distributed systems are viewed as a single virtual DSA by clients that are otherwise unable to "chase" (i.e. follow) referrals by themselves.”
In the example shown at http://www.openldap.org/doc/admin24/overlays.html#Chaining
Is the chaining overlay example used to forward write requests from the syncrepl slaves to the master server?
