Hello Team,

I am facing an issue with setting up OpenLDAP multimaster replicaiton. It is happening only one time and it is giving an error in the server log file that "hdb_dn2id: get failed: DB_NOTFOUND: No matching key/data pair found".

Below are my configuration details.

Operating system: Ubuntu 12.04.2
