Hi @prashardan ,

You may have a look

https://experienceleaguecommunities.adobe.com/t5/adobe-experience-manager/aem6-5-how-to-get-user-details-and-the-groups-the-user-is/td-p/392376

As mentioned in above blog below point returns required data which can be processed in frontend to extract the required group

http://localhost:4502/bin/security/authorizables.json?filter=admin

here admin is user id

https://stackoverflow.com/questions/34285379/how-can-i-check-if-logged-in-user-is-admin-or-members-of-the-administrators-grou

 

Or we can write custom logic in servlet and call that servlet in frontend JS

Below is a sample servlet which returns list of principal name of groups

 

package com.example.group.core.servlets;//write your package name import com.google.gson.JsonArray; import com.google.gson.JsonObject; import org.apache.jackrabbit.api.security.user.Group; import org.apache.jackrabbit.api.security.user.User; import org.apache.jackrabbit.api.security.user.UserManager; import org.apache.sling.api.SlingHttpServletRequest; import org.apache.sling.api.SlingHttpServletResponse; import org.apache.sling.api.servlets.SlingAllMethodsServlet; import org.osgi.service.component.annotations.Component; import javax.jcr.RepositoryException; import javax.servlet.Servlet; import javax.servlet.http.HttpServletResponse; import java.io.IOException; import java.util.Iterator; import java.util.logging.Logger; @Component( service = {Servlet.class}, property = { "sling.servlet.paths=/bin/getUserGroups", "sling.servlet.methods=GET" } ) public class UserGroupsServlet extends SlingAllMethodsServlet { private static final Logger logger = Logger.getLogger(UserGroupsServlet.class.getName()); @Override protected void doGet(SlingHttpServletRequest request, SlingHttpServletResponse response) throws IOException { JsonObject jsonResponse = new JsonObject(); JsonArray groupsArray = new JsonArray(); try { UserManager userManager = request.getResourceResolver().adaptTo(UserManager.class); User user = getUser(request.getUserPrincipal().getName(), userManager); if (user == null) { response.setStatus(HttpServletResponse.SC_NOT_FOUND); jsonResponse.addProperty("error", "User not found."); response.getWriter().write(jsonResponse.toString()); return; } Iterator<Group> userGroups = user.memberOf(); while (userGroups.hasNext()) { Group group = userGroups.next(); if (group != null) { groupsArray.add(group.getPrincipal().getName()); } } jsonResponse.add("groups", groupsArray); jsonResponse.addProperty("userId", request.getUserPrincipal().getName()); } catch (RepositoryException e) { response.setStatus(HttpServletResponse.SC_INTERNAL_SERVER_ERROR); jsonResponse.addProperty("error", "Repository exception: " + e.getMessage()); } response.setContentType("application/json"); response.getWriter().write(jsonResponse.toString()); } private User getUser(String userId, UserManager userManager) { try { return (User) userManager.getAuthorizable(userId); } catch (RepositoryException e) { logger.severe("Error getting user: " + e.getMessage()); } return null; } }

    Hi @prashardan 

    You need to write a custom servlet and call from javascript to know the user group.

    There is a OOTB servlet but that did not return groups, just return user info

    http://localhost:4502/libs/cq/security/userinfo.json?cq_ck=1724417012162
