[389-users] SubjectAltName MMR question

[Prashanth Sundaram]

Hi All,

Which one of the case below is suitable for a Multi-Master replication. I
have a load balancer with ldap.domain.com, which is what clients will use to
authenticate.

Question:
Which one is a better implementation? What are the trade-offs? Please input
your feedback as it might be useful for someone coming this way later. This
can serve as a knowledge bank.

Case-I
ldap01: server-cert with cn=ldap01.domain.com, subjAltName=ldap.domain.com
ldap02: server-cert with cn=ldap02.domain.com, subjAltName=ldap.domain.com
-MMR with tls throws error when ³Check hostname against name in certificate
for outbound SSL connections² option is enabled. But RH recommends it to be
turned ON.

Case-II
ldap01: server-cert with cn=ldap.domain.com, subjAltName=ldap01.domain.com,
ldap02.domain.com
ldap01: server-cert with cn=ldap.domain.com,
subjAltName=ldap01.domain.com,ldap02.domain.com
-Does not comply with the requirement that ³server-cert² should have
hostname as cn.I found this method working perfectly fine.
