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?

Yes, correct.

I am trying to create a master-slave replication with chaining overlay
enabled in the slave to redirect writes request to the master.
I have it working using ldap:// but I have not been able to configure
the chain overlay using a secure connection ldaps:// (running on port
5636 on the master)
My master server do not require client certificates.,
I added the following lines:
overlay chain
chain-uri "ldaps://masterldap.example.com:5636"
chain-idassert-bind bindmethod="simple"
binddn="cn=Manager,dc=example,dc=com"
credentials="secret"
mode="self"
tls_cacert="/path/to/my/CA/cert.pem"
chain-return-error TRUE
But I get "TLS negotiation failure" on the syslog
I am using ldaps:// for replication, but I can't configure it for
chaining
Any hints?

"There are very few chain overlay specific directives; however,
directives related to the instances of the ldap backend that may be
implicitly instantiated by the overlay may assume a special
meaning when used in conjunction with this overlay. They are described
in slapd-ldap(5), and they also need to be prefixed by chain-."
So have a read of man slapd-ldap for the tls statements.
