 Kafka ships with a pluggable Authorizer and an out-of-box authorizer implementation that uses zookeeper to store all the acls. Kafka acls are defined in the general format of "Principal P is [Allowed/Denied] Operation O From Host H On Resource R". You can read more about the acl structure on KIP-11. In order to add, remove or list acls you can use the Kafka authorizer CLI. By default, if a Resource R has no associated acls, no one other than super users is allowed to access R. If you want change that behavior, you can include the following in broker.properties.
 <pre>allow.everyone.if.no.acl.found=true</pre>
 One can also add super users in broker.properties like the following.
-<pre>super.users=User:Bob,User:Alice</pre>
+<pre>super.users=User:Bob;User:Alice</pre>
