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(userNamepassworddomainsearchItem); 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
