Answer 1

The property name you're looking for is sAMAccountName . Here's a list of the available attributes.

Answer 2

I did it this way it worked great:

1- Add reference to Active Directory services DLL

2- Add using in your controller:

 using System.DirectoryServices.AccountManagement;

than I created a function to store All Active directory users in database table bellow is the code hope help someone needs it.

    public ActionResult Create()
    {


        List<MyADUsers> TheAllADUsers = new List<MyADUsers>();

        var context = new PrincipalContext(ContextType.Domain, "MyDoman.org");
        var searcher = new PrincipalSearcher(new UserPrincipal(context));

        foreach (var result in searcher.FindAll())
        {

            TheAllADUsers.Add(new MyADUsers { ADUserName = result.SamAccountName, AD_IsMemberOf = result.UserPrincipalName, FullName = result.Name });

        }

        db.MyADUsersContext.AddRange(TheAllADUsers);
        db.SaveChanges();


        return View();
    }
