Thanks for the response

How to use the session and authenicate the current user is admin or whether the user belong to administrator group?

Because using the below code , it is giving NULL POINTER exception

ResourceResolver resourceResolver = resourceFactory.getAdministrativeResourceResolver(null);   

Session session = resourceResolver.adaptTo(Session.class);

UserManager currentUser = resourceResolver.adaptTo(UserManager.class);

Please suggest some other code to resolve this issue

Thanks & Regards,

Admin session is not recommended in 6.x. Use service users to get the session and thereby current user's properties. You can get groups within Authorizable. You may have to modify the code based on AEM version that you use.

something like

Session session = resourceResolver.adaptTo(Session.class);

UserManager userManager = resourceResolver.adaptTo(UserManager.class);

Authorizable auth = userManager.getAuthorizable(session.getUserID());

Iterator<Group> groups = auth.memberOf();



  //Create a UserManager instance from the session object

  UserManager userManager = ((JackrabbitSession) session).getUserManager();

users= userManager.findAuthorizables("jcr:primaryType", "rep:User");

Make sure to user current user session

Session userSession = slingRequest.getResourceResolver().adaptTo(Session.class);

final UserManager userManager = slingRequest.getResourceResolver().adaptTo(UserManager.class);

final User user = (User) userManager.getAuthorizable(userSession.getUserID());

Boolean isadmin = user.isAdmin()

We have many AEM articles that show use of using a System user - ie - Scott's Digital Community: Querying Adobe Experience Manager 6.4 JCR data

That is your issue. You should be using a System user.
