How to obtain email address with window authentication

Question

I am designing a web application using the ASP.net MVC framework. I would like to use Windows Authentication and do Role Checks using the Role Manager SQLRoleProvider.

Answer 1

In MVC5 application give the action as given below

  public ActionResult Index()
        {
            string name = System.Security.Principal.WindowsIdentity.GetCurrent().Name;
            ViewBag.Name = name;
            ViewBag.Email = uEmail(User.Identity.Name.Replace(@"YOURDOMAIN\", ""));
            return View();
        }

Change the YOURDOMAIN to your domain name. And give the uEmail function as given below. Also add the reference to using System.Security.Principal and using System.DirectoryServices.

private string uEmail(string uid)
        {
            DirectorySearcher dirSearcher = new DirectorySearcher();
            DirectoryEntry entry = new DirectoryEntry(dirSearcher.SearchRoot.Path);
            dirSearcher.Filter = "(&(objectClass=user)(objectcategory=person)(mail=" + uid + "*))";

            SearchResult srEmail = dirSearcher.FindOne();

            string propName = "mail";
            ResultPropertyValueCollection valColl = srEmail.Properties[propName];
            try
            {
                return valColl[0].ToString();
            }
            catch
            {
                return "";
            }

        }
