I'm using ACE - 12.0.11.0 - Kafka consumer node to connect with a Kafka cluster using Kerberos authentication . below are the details on how I configured the Kerberos auth dependent things in integration node.





when I start my app with the above properties . I'm just getting the below error even though JAAS config seems good to me.
