Another Samba / slapd problem

I have a few ClearOS systems, all running ClearOS7, latest update. One system (SAN2) is just a basic back-up system for the entire network. It networks happily with all othe systems using rsync, filezilla, etc. It used to work with Windows systems in the network, as I set it up without an Account Manager system, just a basic filesharing system. Suddenly, my SAN2 system has an Account Manager, and it is offline. I assume it was entered into the system via yum update, as I cannot remember having done that myself. Obviously I cannot use Samba now.
I have seen the different posts on this forum, so I know it will not be easy to remove slapd. I can rebuild the system from scratch which would be a bit of an embarrasment. Before doing that and before I spend too much time on this common issue, I would be interested to know whether there currently is an easy fix so that I can re-use Samba for simple filesharing. Status of slapd:
