body: <p>I create a KafkaUser to access Kafka topic on cloud from external, its definition as following, I can use SSL mode to access this topic from external with port 9094.</p>
  <pre><code>apiVersion: kafka.strimzi.io/v1beta1

  <p>Now inside cloud, I am going to use port 9092 to access this topic without any authentication and authorization, is it possible?</p>
  <p>When I run consumer, it complains TOPIC_AUTHORIZATION_FAILED.</p>
  <pre><code>bin/kafka-console-consumer.sh --bootstrap-server localhost:9092 --group data-group --topic data-topic

  <p>My question is, I want to access topic with port 9092 without any authorization, how to do it?</p>
