Replication errors with 2.3.40

["Diego Woitasen" <diegows@xtech.com.ar>]

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.
