I just have a 3-way multi-master replication with openldap for cn=config and HDB. Sometime in the log, I have this error/warning :

<= bdb_equality_candidates: (cn) not indexed

How can I fix it ? just add olcDbIndex cn eq ???

Yes.

and my second question is why this warning occurs ?

There should be an LDAP client doing search with such filter: (cn=abdc)
