Hello Friends,
        I am trying to get member list from group in active directory but I am not getting list from AD so far.

        The Code is,

        GroupPrincipal gp = GroupPrincipal.FindByIdentity("PrincipalContext","GroupName")

       I am getting null value only from this code.

Can any one help me !!!

1.Add reference of System.DirectoryServices in your project. 2.using System.DirectoryServices; 3.call the method passing the arguments: string searchItem=textBox1.Text;//User to search GetAssociateInfo(userName,password,domain,searchItem); 4.Define the below : private bool GetAssociateInfo(string userName, string password, string domain, string searchItem) { bool authentic = false; try { DirectoryEntry entry = new DirectoryEntry("LDAP://" + domain, userName, password); DirectorySearcher searcher = new DirectorySearcher(entry); searcher.Filter = string.Format("(&(objectCategory=person)(anr={0}))", searchItem); searcher.PropertiesToLoad.Add("givenName"); // first name searcher.PropertiesToLoad.Add("sn"); // last name searcher.PropertiesToLoad.Add("mail"); searcher.PropertiesToLoad.Add("userPrincipalName"); searcher.PropertiesToLoad.Add("telephoneNumber"); searcher.PropertiesToLoad.Add("title"); searcher.PropertiesToLoad.Add("mobile"); searcher.PropertiesToLoad.Add("department"); searcher.PropertiesToLoad.Add("manager"); searcher.PropertiesToLoad.Add("employeeBirthDate"); SearchResultCollection results; results = searcher.FindAll(); List listSearchResult = new List (); if (results.Count > 0) { foreach (SearchResult sr in results) { ADDetails aDDetails = new ADDetails(); if (sr.Properties["mail"].Count > 0) { aDDetails.email = sr.Properties["mail"][0].ToString(); } if (sr.Properties["givenName"].Count > 0) { aDDetails.First_name = sr.Properties["givenName"][0].ToString(); } if (sr.Properties["sn"].Count > 0) { aDDetails.Last_name = sr.Properties["sn"][0].ToString(); } if (sr.Properties["title"].Count > 0) { aDDetails.Title = sr.Properties["title"][0].ToString(); } if (sr.Properties["userPrincipalName"].Count > 0) { if (sr.Properties["userPrincipalName"][0].ToString().ToUpper().Contains("@CTS.COM") || sr.Properties["userPrincipalName"][0].ToString().ToUpper().Contains("@cognizant.com")) { aDDetails.User_ID = sr.Properties["userPrincipalName"][0].ToString().Remove(6, sr.Properties["userPrincipalName"][0].ToString().Length - 6); } else { aDDetails.User_ID = sr.Properties["userPrincipalName"][0].ToString(); } } if (sr.Properties["telephoneNumber"].Count > 0) { aDDetails.Vnet = sr.Properties["telephoneNumber"][0].ToString(); } if (sr.Properties["mobile"].Count > 0) { aDDetails.Mobile = sr.Properties["mobile"][0].ToString(); } if (sr.Properties["department"].Count > 0) { aDDetails.Department = sr.Properties["department"][0].ToString(); } if (sr.Properties["manager"].Count > 0) { aDDetails.Manager = sr.Properties["manager"][0].ToString(); int index = sr.Properties["manager"][0].ToString().IndexOf(",OU="); string manager = sr.Properties["manager"][0].ToString().Substring(3, index - 3); if (manager.Contains(@"\")) { int i = manager.IndexOf(@"\"); manager = manager.Remove(i, 1); } aDDetails.Manager = manager; } listSearchResult.Add(aDDetails); } object nativeObject = entry.NativeObject; authentic = true; var source = new BindingSource(); source.DataSource = listSearchResult; dataGridView1.DataSource = source; if (dataGridView1.RowCount > 0) { dataGridView1.Show(); label4.Text = "Total Result Found : " + (dataGridView1.RowCount - 1).ToString(); } else { MessageBox.Show("No result found!!"); } } } catch (DirectoryServicesCOMException) { } return authentic; }

You can include System.DirectoryServices in your code base and then try below code AppDomain.CurrentDomain.SetPrincipalPolicy(System.Security.Principal.PrincipalPolicy.WindowsPrincipal); var entry = new DirectoryEntry(@"LDAP://ads.abc.com", @"user 1", @"password123"); var searcher = new DirectorySearcher(entry); searcher.Filter = "(&(ObjectClass=user) (cn=user 1))"; searcher.SearchScope = SearchScope.Subtree; var results = searcher.FindOne(); User 1 I assume is user in your system with password123 . First it looks the directoryentry and then filter that user 1 Now results should contain the data for user 1 twitter @sumitjolly
