title: Can I Use SSL and ACL authentication/authorization only for SSL listener (not for PLAINTEXT) in Kafka?
body: <p>I would like to run a Kafka cluster with 2 listeners. One SSL and one PLAINTEXT listener.
  The SSL listener should be secured by authentication/authorization via SSL and ACL. Only known users should be allowed to access it.</p>
  <p>On the PLAINTEXT port any user or anonymous user should have full access.</p>
  <p>If I set the property</p>
  <pre><code>allow.everyone.if.no.acl.found=false
  </code></pre>
  <p>however, anonymous users will no longer be able to access the PLAINTEXT port. Is there any way to configure the system as described above?</p>
