Is there a recommended way to discontinue the use of the ppolicy overlay?

The only way I've found that works is to stop the ldap server and using slapcat/edit/slapadd eradicate all the ppolicy attributes (combined with removing the ppolicy overlay and schema from the slapd.conf file).

I'm attempting this on RHEL7 with OpenLDAP 2.4.46 (local built).

Thanks, - Frank
