Hello everyone,

I'm trying to convert my two node replicated OpenLDAP pair to a three-way pair and am having trouble with configuring the slapd.conf files. Can anyone tell me what I need to add here? Below is my newly modified slapd.conf file with the system03 addition:


----- slapd.conf on system01 replicating to system02 and system03 -----

serverID 001

You should definitely use different rid for these two syncrepl statements.

I assume you have specified different serverID in your other two config files.

Also, but probably unrelated, you shouldn't be able to have two values for updateref. Send updates to only one server.

Other than that, your config ressembles the example from the admin guide:
http://www.openldap.org/doc/admin24/replication.html#N-Way%20Multi-Master%20replication
