I have a classic master-slave replication scenario with OpenLDAP 2.3.40. I have some problems with replication, it fails random with error like I pasted above.
I don't understand with I get "No such attribte..." if the attribute exists in both servers. I resinchronized the servers manually but the problem happened again. This errors happens frequently with Samba attributes, because are the most active.
This LDAP is a Samba password backend.
I pasted the log file and a search in both servers.
