[jira] [Created] (KAFKA-10279) Allow dynamic update of certificates with additional SubjectAltNames

Rajini Sivaram created KAFKA-10279:
--------------------------------------

             Summary: Allow dynamic update of certificates with additional SubjectAltNames
                 Key: KAFKA-10279
                 URL: https://issues.apache.org/jira/browse/KAFKA-10279
             Project: Kafka
          Issue Type: Improvement
          Components: security
            Reporter: Rajini Sivaram
            Assignee: Rajini Sivaram
             Fix For: 2.7.0


At the moment, we don't allow dynamic keystore update in brokers if DN and SubjectAltNames don't match exactly. This is to ensure that existing clients and inter-broker communication don't break. Since addition of new entries to SubjectAltNames will not break any authentication, we should allow that and just verify that new SubjectAltNames is a superset of the old one.
