We have an LDAP cluster on RHEL 8. We were running 18.104.22.168-1.module_el8+13163+e27841f7.x86_64 and recently updated to 2.0.15-1.module_el8+14185+adb3f555.x86_64.
Since then, replication fails from any server to any other server. What I am seeing in /var/log/dirsrv/slapd-pro01/errors is:
[19/Jul/2022:15:20:20.174222661 -0400] - ERR - NSMMReplicationPlugin - bind_and_check_pwp - agmt="cn=pro01topro02" (pro02:636) - Replication bind with SIMPLE auth failed: LDAP error -1 (Can't contact LDAP server) (TLS: hostname does not match subjectAltName in peer certificate)
[19/Jul/2022:15:46:41.092806631 -0400] - 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 "pro02.example.com:636")
I regenerated and reinstalled the certs for pro01 and pro02, adding the SAN. But that did not help things any.
Did I miss something in the update to v2?
Thanks in advance,
