 *
 * <p><h4>Notes</h4>

 *
 * <p><h4>Usage</h4>
 * For SSO realm that uses JAAS
 * The configuration must be the same as for JAASUserRealm plus
 * injection of an instance of class HashSSORealm using setSSORealm()
 * methode. This is intended to be used with the correct LoginModule
 * and its fitting .conf configuration file as described in JAAS documentation.
