How to get logged-in user/group information in WebLogic Portal 10.3.2

Question

Hi bros.
I have a codesnipet to get information about user who actually logged in weblogic portal:
import javax.security.auth.Subject;
import javax.security.auth.login.LoginException;
import com.bea.p13n.security.Authentication;
import com.bea.portal.tools.security.user.*;
public class UGMSummary {
     private static final String username = "weblogic";
     private static final String password = "webl0gic";
     public UGMSummary(){
     public void test(){
          try {
               Subject tmp = Authentication.authenticate(username, password);
               //PolicyItem pi = new PolicyItem();
               //System.out.println("######## " + Authentication.getCurrentSubject().toString());
               UserIDBuilder builder = new UserIDBuilder();
               UserID uid = builder.createResourceID();
               System.out.println("######## Admin ? " + Authentication.isAdministrator(tmp));
               System.out.println("######## Anonymous ? " + Authentication.isAnonymous(tmp));
               System.out.println(" ######## " + uid.getUserName());
          } catch (LoginException e) {
               System.out.println(e.getMessage());
               //e.printStackTrace();
}Some println commands above are used to mark in console. I can ensure that there is an user (admin) logged in weblogic system by executing command: Authentication.isAdministrator(tmp);
Output of codesnipet above is:
######## Admin ? true
######## Anonymous ? false
######## nullMy problem is impossible to use UserID object to get username of weblogic user. Output of command: uid.getUsername() is: null
Somebody tell me why my code doesn't work though it can authenticate an user.
Thank in advance.
ps:
Some Javadoc for UserID can be found here:

Hi, Kevin.
I'm glad to see your response again. I found some interesting information from your recommendation link. At this time, I know that impossible to get users/groups information by using DelegatedAtnProxyManagerControlFacade (ref: http://download.oracle.com/docs/cd/E15919_01/wlp.1032/e14255/com/bea/portal/tools/ugm/controls/DelegatedAtnProxyManagerControlFacade.html) interface.
But, I dont know how to get an instance of an object that implemented this interface. My friend give me a codesnipet that shown the way to get a DelegatedAtnProxyManagerControlFacade by using this codesnipet in a GlobalController:
      try
        DelegatedAtnProxyManagerControlFacade delegatedAtnProxyManager = (DelegatedAtnProxyManagerControlFacade)getControl(DelegatedAtnProxyManagerControlFacade.class);
      catch (PolicyRefException e)
        reportPolicyRefException(e);
      catch (OperationNotSupportedException e)
        reportOperationNotSupportedException(e);
      }But I dont know what global.GlobalController actually is ?
I've asked Google for information but I got nothing. Do you know any documentation that describes about this controller ?
Thanks, regards !
