Thanks for prompt reply Quanah. Will upgrade to 2.4.58 as you suggested. Do you foresee any issues with performing in-place upgrade or should we re-index the database by re-importing the data ( we are using mob)?

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.

That's not what result code 16 indicates.  It means that the MOD operation attempted to change an attribute that didn't exist on the target entry.

In any case, replication of any type is not safe with OpenLDAP 2.4.49, you need to upgrade to the current release (2.4.58).  Additionally, you must use delta-syncrepl replication.
