Can openldap sync Directory Information Tree data using syncrepl from opendj as provider?

Question

My scenario is that we have a centralized Opendj in cloud and we want to sync(pull) the Directory data from this Opendj to an Openldap instance running in same cloud. I am trying to achieve this by using syncrepl by configuring Openldap slapd.conf file. In the file provider ldap://opendjendpoint.my.org:389 is Opendj

syncrepl rid=1
provider=ldap://opendjendpoint.my.org:389
type=refreshOnly
interval=00:00:05:00"
searchbase="o=my.org,c=us"
filter="(objectClass=*)"
scope=sub
attrs="*,+"
schemachecking=off
bindmethod=simple
binddn="cn=syncuser,o=my.org,c=us"
credentials=somepass

Question is though opendj runs an LDAP server, but using syncrepl in openldap can I connect to it. My thought is that openldap can connect only with RFC4533 implementations(LDAP sync Protocol) and opendj does not implement it. Can somebody provide input on this?

Answer 1

As you've noticed OpenDJ doesn't implement RFC4533 which is an experimental RFC. But when replication is enabled, all changes can be retrieved via LDAP (subject to access controls), from the cn=changelog suffix. Synchronization tools such as LSC Project can consume these changes and replay them against other LDAP servers.
