be_modify failed(16)

Hello All,

OpenLDAP server 2.4.49 Setup with replication

Noticing following error messages in server logs,

Apr 14 19:56:19 openldap-service-0 slapd[51]: syncrepl_null_callback : error code 0x10 Apr 14 19:56:19 openldap-service-0 slapd[51]: syncrepl_entry: rid=103 be_modify failed (16)

As the error code “16” suggested, validated the schema across participating nodes and found no discrepancies in the schema configuration across nodes.

However, we are noticing that one of the entries is missing from one node out of three participating replicas (multi master).

Any pointers on where to start to debug to understand the issue and fix it.

Thanks in advance.
