/**
 * 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 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";
