Hi, I'm following the instructions to setup replication in CHAPTER 2. CONFIGURING SINGLE-SUPPLIER REPLICATION<https://docs.redhat.com/en-us/documentation/red_hat_directory_server/12/pdf/configuring_and_managing_replication/Red_Hat_Directory_Server-12-Configuring_and_managing_replication-en-US.pdf> USING THE WEB CONSOLE<https://docs.redhat.com/en-us/documentation/red_hat_directory_server/12/pdf/configuring_and_managing_replication/Red_Hat_Directory_Server-12-Configuring_and_managing_replication-en-US.pdf>
I get a "Error (-1) - LDAP error: Can't contact LDAP server - no response received " in the GUI The logs on supplier say this: [06/Jan/2026:11:47:51.180037306 +0000] - ERR - slapi_ldap_bind - Could not send bind request for id [cn=replication manager,cn=config] authentication mechanism [SIMPLE]: error -1 (Can't contact LDAP server), system error -5987 (Invalid function argument.), network error 0 (Unknown error, host "second.xxx.com:636") LDAPS definitely is enabled and working on the secondary though, I've used ldapsearch to confirm it: ldapsearch -x -b ou=users,dc=com -H ldaps://second.xxx.com -D "cn=ldap_ro,dc=com" -W The logs on the consumer don't show anything strange There's no failed bind so it's not getting that far. Suspecting that it might have something to do with the self signed ssl I've added the primary CA cert to the secondary and vice versa, Trusted Certificate Authorities but no joy. Any help appreciated Arnaud
