I used the following docs to setup MMR on my CentOS 6.5 server:
http://trialanderrorlinux.wordpress.com/2013/06/22/ldap-directory-server-on-centos-6-3-using-tls/
http://linuxrackers.com/doku.php?id=389_directory_server_setup_using_centos6_rhel6
http://directory.fedoraproject.org/docs/389ds/howto/howto-walkthroughmultimasterssl.html
http://admintweets.com/389-ds-directory-services-multi-master-replication-setup/
I am not doing TLS between the master just between the clients and servers.  Now i am looking at the error logs and I am seeing an error in the log:

Any idea what it could be?  When I first set this up I did remember to init the replica.
