/**
 * 
 * Factory to create a {@link SubjectAuthenticationService}.
 * 
 * 
 * Two properties can be set: allowActorIdOverwrite & principalClassName
 * 
 * 
 * principalClassName configuration property specifies the class name of the principal that should
 * be used from the current subject. This could be for example org.jboss.security.CallerIdentity in
 * an JBoss AS.
 * 
 * 
 * If not actorId is set, the name of that principal is used as the currently authenticated actorId.
 * If an actorId!=null is set (via setActorId) this one overwrites the principal. This behavior is
 * configurable via the allowActorIdOverwrite attribute. If this is set to false, setActorId is
 * simply ignored.
 * 

 * 

 * Example:
 * 
 * 
 *  * <service name="authentication">
 *   <factory>
 *      <bean class="org.jbpm.security.authentication.SubjectAuthenticationServiceFactory">
 *         <field name="principalClassName"> <string value="org.jboss.security.CallerIdentity" /> </field>
 *         <field name="allowActorIdOverwrite"> <boolean value="true" /> </field>
 *      </bean>
 *   </factory>
 * </service>
