/**
* A JAAS Authentication Broker that uses different JAAS domain configurations
* depending if the connection is over an SSL enabled Connector or not.
*
* This allows you to, for instance, do DN based authentication for SSL connections
* and use a mixture of username/passwords and simple guest authentication for
* non-SSL connections.
* <p>
* An example <code>login.config</code> to do do this is:
* <pre>
* activemq-domain {
* org.apache.activemq.jaas.PropertiesLoginModule sufficient
* debug=true
* org.apache.activemq.jaas.properties.user="users.properties"
* org.apache.activemq.jaas.properties.group="groups.properties";
* org.apache.activemq.jaas.GuestLoginModule sufficient
* debug=true
* org.apache.activemq.jaas.guest.user="guest"
* org.apache.activemq.jaas.guest.group="guests";
* };
*
* activemq-ssl-domain {
* org.apache.activemq.jaas.TextFileCertificateLoginModule required
* debug=true
* org.apache.activemq.jaas.textfiledn.user="dns.properties"
* org.apache.activemq.jaas.textfiledn.group="groups.properties";
