A simple application for adding users to active directory.


Add users to active directory without installing windows server or active directory roles and features.

Using the code

To add a new user to Active Directory we use three classes:

  1. System.Net.NetworkInformation: We want to add another user to our domain therefore at first we should find out our domain name. We find its name by using this code:
  2. string stringDomainName = System.Net.NetworkInformation.IPGlobalProperties.GetIPGlobalProperties().DomainName;
  3. PrincipalContext: is a container of domain which all operations are performed against it. To add another user, PrincipalContext uses credential specified by username and password. This credential is used to connect to active directory therefore the user with this credential must has permission to add users.
  4. UserPrincipal: Making another user and add it to active directory is very simple. We just need to initialize an instance of UserPrincipal by using the specified context from the pervious part and also username and password of new user. Then we just assign input textboxes data to related properties of UserPrincipal.
private void button1_Click(object sender, RoutedEventArgs e)
        string stringDomainName = System.Net.NetworkInformation.IPGlobalProperties.GetIPGlobalProperties().DomainName;
        PrincipalContext PrincipalContext4 = new PrincipalContext(ContextType.Domain, stringDomainName, 
          textboxOu.Text, ContextOptions.SimpleBind, textboxAdminUsername.Text, passwordboxAdminPassword.Password);
        UserPrincipal UserPrincipal1 = new UserPrincipal(PrincipalContext4, 
          textboxLonOnName.Text, passwordboxUserPass.Password, true);
        //User Logon Name
        UserPrincipal1.UserPrincipalName = textboxSamAccountName.Text;
        UserPrincipal1.Name = textboxName.Text;
        UserPrincipal1.GivenName = textboxGivenName.Text;
        UserPrincipal1.Surname = textboxSurname.Text;
        UserPrincipal1.DisplayName = textboxDisplayName.Text;
        UserPrincipal1.Description = textboxDescription.Text;
        if (radiobuttonEnable.IsChecked == true)
            UserPrincipal1.Enabled = true;
            UserPrincipal1.Enabled = false;
        MessageBox.Show("Saved Sucessfully");
    catch (Exception ex)
