             Summary: SSL/TLS: Certificate Domain is ignored
                 Key: CASSANDRA-10970
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-10970
             Project: Cassandra
          Issue Type: Bug
            Reporter: Matthias Brandt


I've set up server_encryption_options as well as client_encryption_options. In 
both settings, I use the same keystore with an wild-card SSL certificate in it. 
It is signed by our own CA, which root certificate is in the configured 
truststore:
{code}
server_encryption_options:
    internode_encryption: all
    keystore: /etc/cassandra/conf/wildcard-cert.keystore
    keystore_password: ""
    truststore: /etc/cassandra/conf/hpo-cacerts
    truststore_password: changeit
    require_client_auth: true

client_encryption_options:
    enabled: true
    keystore: /etc/cassandra/conf/wildcard-cert.keystore
    keystore_password: ""
    require_client_auth: false
{code}

The certifcate's subject is:
{code}CN=*.my.domain.com,OU=my unit,O=my org{code}

When I deploy this setting on a server which domain is 
node1.my.*other-domain*.com a connection via cqlsh wrongly works. Additionally, 
the inter-node connection between other nodes in this wrong domain also works.

I would expect that the connection would fail with a meaningful error message.
