All,

I'm trying to get N-Way Multi-master replication working, and can see each server polling each other but replication doesn't see to update.

I have two servers auth03 and auth04. Both servers are Centos 6.5 with OpenLDAP 2.4.23-34.el6_5.1 from the Base/Updates CentOS repository.

What I see is that each server seems to contact the other and both get log entries like this. I can post more logs if need be. I haven't been able to find much on "got empty syncUUID"

Apr 14 15:44:32 auth03 slapd[1467]: daemon: epoll: listen=11 active_threads=0 tvp=zero Apr 14 15:44:32 auth03 slapd[1467]: connection_get(22) Apr 14 15:44:32 auth03 slapd[1467]: connection_get(22): got connid=0 Apr 14 15:44:32 auth03 slapd[1467]: =>do_syncrepl rid=004 Apr 14 15:44:32 auth03 slapd[1467]: =>do_syncrep2 rid=004 Apr 14 15:44:32 auth03 slapd[1467]: do_syncrep2: rid=004 got empty syncUUID with LDAP_SYNC_ADD Apr 14 15:44:32 auth03 slapd[1467]: connection_get(22) Apr 14 15:44:32 auth03 slapd[1467]: connection_get(22): got connid=0 Apr 14 15:44:32 auth03 slapd[1467]: daemon: removing 22 Apr 14 15:44:32 auth03 slapd[1467]: do_syncrepl: rid=004 rc -1 retrying (29 retries left)

Here is the configs for each server: Each server has a unique server ID as well. I haven't tried to get my main user database replicating, as it appears the config database isn't replicating yet.

Please let me know what additional info I may need to provide.
