Grouper Users - Open Discussion List

[Chris Hyzer <>]

Its kind of complicated unfortunately.  If you don’t know if there is a session, you could check, and if you find one use it (root?) and if not, create…

 

Your way will probably work fine, but this way will definitely work now and in the future without problem:

 

    GrouperSession grouperSession = GrouperSession.staticGrouperSession();

    boolean startedGrouperSession = false;

    if (grouperSession == null) {

      grouperSession = GrouperSession.startRootSession(false);

      startedGrouperSession = true;

    }

    if (!PrivilegeHelper.isWheelOrRoot(grouperSession.getSubject())) {

      grouperSession = grouperSession.internal_getRootSession();

    }

    try {

      boolean isWheelOrRoot = (Boolean)GrouperSession.callbackGrouperSession(grouperSession, new GrouperSessionHandler() {

       

        public Object callback(GrouperSession grouperSession) throws GrouperSessionException {

          

          boolean isWheelOrRootLogic = false; 

          //DO WORK NOTE YOU MIGHT NEED FINAL VARS

       

          return isWheelOrRootLogic;

        }

      });

    } finally {

      if (startedGrouperSession) {

        GrouperSession.stopQuietly(grouperSession);

      }

    }

 

 

Thanks,

Chris

Hi,

 

Now, when I try yo login as someone who is in the sysadmingroup (wheel group) and I am calling PrivilegeHelper.isWheelOrRoot(sub) from the GrouperUiFilter's doFilter method, it throws exception while executing GrouperSession.staticGrouperSession(). 

 

It works if I start session using GrouperSession.start(subjectLoggedIn) and stop it after checking if the subject is in wheelGroup or not. I want to confirm that it does not have any side effects.

 

Thanks,

 

Vivek

Thanks Chris!

 

It worked fine but I had to catch IllgealStateException coming out of GrouperSession.staticGrouperSession() from the isWheelOrRoot method. Exception is thrown only when non wheel members try to log in. Hope it does not cause any issues later.

I think the GrouperUiFilter might be better since it is called for all the UIs.  Otherwise sounds good.

 

Thanks,

Hi,

 

I need to show/hide some links based on if the logged in user is root/wheel group member or not. PrivilegeHelper class has method isWheelOrRoot(Subject subject). 

If I change the LoginCheckFilter and add another session attribute something like:

 

Session.setAttribute("RootOrWheel", true|false)

 

And then read it on the jsp pages to decide if the links/buttons should be shown or not.

 

What do you think, is this a good idea ?? Any other ideas??

 

Thanks
