Yup, you are using two different suffixes/backends between the suppliers and consumers.  The consumers are only accepting replication updates for "dc=test,dc=co,dc=uk", but the supplier is trying to replicate "dc=conscious,dc=co,dc=uk".  They have to be the same ;-)

sidenote, If i run the below without any filtering applied by me


ldapsearch -x -b "dc=test,dc=co,dc=uk,cn=config" -H ldaps://myserver -D "cn=replication manager,cn=config" -W
Enter LDAP Password:

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

Mark



i get:

My other concern is about the error message above, is that from a RHEL 8 replica?

this is from the var/log/dirsrv/slapd-host/* logs




If so, this indicates replication is not setup properly on that suffix, but you say all the rhel 8 replicas are working.

we only have the 1 master node on 8, apologies for any confusion.


Thanks

Does anyone know anything that I could check for the error to get around this?


Thankyou kindly.
