Migrating to new ldap server and getting problems.

OS:   Rocky Linux 8 (== RHEL/CentOS 8). Fully updated.

LDAP software:   symas-openldap-servers-2.6.1-2.el8.x86_64

cn=config and and data import (via ldif) on master. Everything look good. start/stop/restart is working. ldap access is working.

Adding "syncprov" on master (to enable producer/consumer mode). Now the slapd on the master/producer crashes on start!
