Get Windows groups (JNA/Windows) Tag(s): JNA


For the current user 

import com.sun.jna.platform.win32.Advapi32Util;

import com.sun.jna.platform.win32.Netapi32Util;

import com.sun.jna.platform.win32.Netapi32Util.Group;



    // https://github.com/twall/jna#readme

    //    you need 2 jars : jna-3.5.1.jar and platform-3.5.1.jar



     Group[] groups = Netapi32Util.getUserGroups(Advapi32Util.getUserName(), Netapi32Util.getDCName());

     for (Group group:groups) {

        System.out.println(group.name);

     }
For a given user 

import com.sun.jna.platform.win32.Netapi32Util;

import com.sun.jna.platform.win32.Netapi32Util.Group;



...



    // https://github.com/twall/jna#readme

    //    you need 2 jars : jna-3.5.1.jar and platform-3.5.1.jar



     Group[] groups = Netapi32Util.getUserGroups("username", Netapi32Util.getDCName());

     for (Group group:groups) {

        System.out.println(group.name);

     }

Implement "userInRole()" method is easy. 


   public static boolean isUserInRole(String user, String role) {

        try {

            Group[] groups = Netapi32Util.getUserGroups(user, Netapi32Util.getDCName());

            boolean isAuthorized = false;

            for (Group group:groups) {

                 if (group.name.equals(role)) {

                     isAuthorized = true;

                     break;

                 }

            }

            return isAuthorized;

        }

        catch (Exception e) {

            return false;

        }

    }
