I have multimaster replication set up on 4 LDAP servers but can't get secure replication working on one of the servers. The setup is like this -- data center 1 data center 2 ldap1 <-------> ldap1 ^ | ^ | / | | | | v | v ldap2 ldap2 each server has its own self-signed cert. I can successfully replicate in all the directions indicated except for replication from data center1 ldap2 to data center1 ldap1. I know that I have the right certificate on ldap2. I can ldapsearch -ZZ from ldap2 to ldap1 successfully using this certificate. I can successfully replicate from data center 2 ldap1 to data center1 ldap1 using this certificate. But replication refuses to work from DC1 ldap2 to DC1 ldap1!!!! The logs say LDAP error: Can't contact LDAP server. Error Code: -1. I've disabled iptables on both data center 1 ldaps. I've rebuilt the replication agreement a dozen times. I've ldapsearch -zz'ed a dozen times. I've reinstalled the CA certificate (using the one from my openldap directory, so I know that it is the same one that is working for ldapsearch -ZZ, as well as exporting it from ldap1 again and reinstalling it). What else can I possibly do to get this working? These are my rpms - # rpm -qa | grep 389 389-ds-base-libs-1.2.11.25-1.el6.x86_64 389-ds-console-1.2.6-1.el6.noarch 389-admin-1.1.35-1.el6.x86_64 389-ds-base-1.2.11.25-1.el6.x86_64 389-admin-console-1.1.8-1.el6.noarch 389-console-1.1.7-1.el6.noarch 389-adminutil-1.1.19-1.el6.x86_64 openssl-1.0.1e-16.el6_5.4.x86_64 # uname -a Linux dc1-ldap2 2.6.32-431.5.1.el6.x86_64 -- 389 users mailing list 389-users@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/389-users
