You can use the below function to fetch LDAP info:

C#

using System.Security.Principal;

private void GetUserName()
        {
            WindowsIdentity ident = WindowsIdentity.GetCurrent();
            WindowsPrincipal user = new WindowsPrincipal(ident);
            string username = StripDomainFromUserName(user.Identity.Name);

            using (DirectoryEntry de = new DirectoryEntry("LDAP://" + StripDomain(user.Identity.Name)))
            {
                using (DirectorySearcher adSearch = new DirectorySearcher(de))
                {
                    adSearch.Filter = "(sAMAccountName=" + username + ")";
                    SearchResult adSearchResult = adSearch.FindOne();

                    UserCredentials.CommitID = username;
                    UserCredentials.UserName = StripLoggedUserName(adSearchResult.Path);
                    UserCredentials.LoginUserName = StripLoggedUserName(adSearchResult.Path);
                    UserCredentials.LoginUserCommitID = username;
                }
            }
        }
