You need to search under "cn=conifg" for objectclass=nsds5replica. not
the database suffix, and you should do so as the directory manager account:

ldapsearch =D "cn=directory manger" -W -b cn=config objectclass=nsds5replica


Can you also provide provide the other information I requested from the
RHEL 8 server?


# dsconf slapd-YOUR_INSTANCE replication get --suffix dc=test,dc=co,dc=uk

# dsconf slapd-YOUR_INSTANCE repl-agmt list --suffix dc=test,dc=co,dc=uk

Is "dc=test,dc=co,dc=uk,cn=config" really an entry under cn=config. 
This looks wrong.
