I have a problem with the N-Way replication multimaster. My enviroiment is debian Stretch and slapd (2.4.47+dfsg-3~bpo9+1) from Stretch backports.
I have configured a cluster with 3 nodes. I have configured to replicate the config database and a normal data mdb database. I followed the documentation and the cluster sync work correctly when all nodes are started.
If i made a change in any node, this change is replicated to the others. My problem appears when i make a change whe one node is down. In this case, the other two nodes repli correctly, and when the downed node start this get all pending changes correctly. And in this point occurs the problem. After the start of downed node, the changes mades in this node are not send to the other two nodes. For other way, the changes mades in the other two nodes (no shutdowned) are sended to all nodes correctly.
I tried this config with a two nodes cluster and the behavior was the same, after reboot slapd do not send more updates.
I have checked the olcServerId because i know that a mistake here can produce similar problems. I really think that it is correct.
The cmdlines of the proccess are:
/usr/sbin/slapd -h ldapi:/// ldap://wbsvisionNode1/ ldap://127.0.0.1/ ldaps:/// -g openldap -u openldap -F /etc/ldap/slapd.d /usr/sbin/slapd -h ldapi:/// ldap://wbsvisionNode2/ ldap://127.0.0.1/ ldaps:/// -g openldap -u openldap -F /etc/ldap/slapd.d /usr/sbin/slapd -h ldapi:/// ldap://wbsvisionNode3/ ldap://127.0.0.1/ ldaps:/// -g openldap -u openldap -F /etc/ldap/slapd.d
