Brokers that make up a cluster gateway can use the BrokerAccessControlList class to authenticate the remote Broker that makes up the other half of the gateway. ACLs are only checked when a Broker opens a connection to the other Broker in the gateway.

You can use the BrokerAdminClient.setClusterGatewayACL method to configure the ACL for the cluster gateway, and the BrokerAdminClient.getClusterGatewayACL method to obtain the ACL information for the gateway. In both cases, a BrokerException will be thrown if basic authentication or SSL is not enabled.
