 * A service bean that is/will be used for all standard idegaweb authentication methods.<br>
 * Also provides plugable behavior for objects that want to be notified when a user logs on and off (see AuthenticationListener interface).<br>
 * This bean is supposed to gradually replace LoginBusinessBean and AccessController/AccessControl and weed out static and obsolete methods.
