title: Kafka authorization and authentication ports
body: <p>I have read the documentation on Kafka security here: <a href="https://kafka.apache.org/documentation/#security_authz_cli" rel="nofollow noreferrer">https://kafka.apache.org/documentation/#security_authz_cli</a></p>
  
  <p>and I was wondering something about the ports they use. For the authentication portion, under 7.2 Encryption and authentication using SSL, they have the statement:</p>
  
  <pre><code>kafka-console-producer.sh --broker-list localhost:9093 --topic test --producer.config client-ssl.properties
  kafka-console-consumer.sh --bootstrap-server localhost:9093 --topic test --consumer.config client-ssl.properties
  </code></pre>
  
  <p>for the use cases of the console consumer and producer.</p>
  
  <p>For the authorization portion, under 7.4 Authorizations and ACL, when showing on how to add to ACLs different permissions for different users, they have the phase:</p>
  
  <pre><code>bin/kafka-acls.sh --authorizer-properties zookeeper.connect=localhost:2181 --add --allow-principal User:Bob --allow-principal User:Alice --allow-host 198.51.100.0 --allow-host 198.51.100.1 --operation Read --operation Write --topic Test-topic
  </code></pre>
  
  <p>So my question is, for the "broker-list" and "bootstrap-server" variable in the authentication portion and the "zookeeper.connect" variable in authorization, does the port and localhost have the be the same? It isn't in the examples given and I'm trying to combine the authentication and authorization parts using SSL. Is they need to be the same or do not need to be the same, why? Any documentation / tutorial on how to do this using purely console only is appreciated. I don't want to use Kerebos. </p>
