Hello colleagues,
Lately we started looking into 389 DS 2.3.6 on RHEL 9 platform.
We followed instructions Configuring and managing replicationhttps://access.redhat.com/documentation/en-us/red_hat_directory_server/12/html-single/configuring_and_managing_replication/index on Red Hat site to establish replication between two remote instances, The instances where previously configured to support TLS channel on port 636 (Enabling TLS-encrypted connections to Directory Serverhttps://access.redhat.com/documentation/en-us/red_hat_directory_server/12/html/securing_red_hat_directory_server/assembly_enabling-tls-encrypted-connections-to-directory-server_securing-rhds) , and we made sure ldapsearch is working with LDAPS:// protocol with the certificate verification (TLS_REQCERT demand).
The following issue with the replication over TLS was observed:
After we ran the command below to configure secure replication: dsconf -D "cn=Directory Manager" -w *** ldaps://server.example.edu repl-agmt create --suffix "dc=example,dc=com" --host "consumer.example.edu" --port 636 --conn-protocol=LDAPS --bind-dn "cn=replication manager,cn=config" --bind-passwd "***" --bind-method=SIMPLE --init consumer.example.edu-RO
the error occurred: Error (-1) Problem connecting to replica - LDAP error: Can't contact LDAP server (connection error)
We double-checked that after we configure clear text replication with the command: dsconf -D "cn=Directory Manager" -w *** ldaps://server.example.edu repl-agmt create --suffix "dc=example,dc=com" --host "consumer.example.edu" --port 389 --conn-protocol=LDAP --bind-dn "cn=replication manager,cn=config" --bind-passwd "***" --bind-method=SIMPLE --init 10.140.133.36-RO
no problem occurred, and the replication completed successfully.
My question is whether this means the replication over TLS required different config steps, and if yes – what they are?
Thank you, - Alex
