On MVC 5, after Signing In, Identity is still Unauthenticated - asp.net-mvc

Question

In my login page, I have sign-in code like this ...
AuthenticationManager.SignIn(new AuthenticationProperties() { IsPersistent = isPersistent }, identity);
However, when I check User.Identity right after Signin, it is still Unauthenticated
this.User.Identity.IsAuthenticated is returning false.
Anything I am missing ??

Answer 1

The this.User.Identity.IsAuthenticated is not true until the next request. In my case I redirect to the Home/Index. Once inside HomeController.Index() method I see that IsAuthenticated == true.
From here: http://msdn.microsoft.com/en-us/library/twk5762b.aspx
The forms-authentication ticket supplies forms-authentication information to the next request made by the browser.

Answer 2

I'm assuming you're using ASP.NET Identity. Here is a working template and see whats different in your code.
Model:
public class LoginViewModel
{
[Required]
[Display(Name = "User name")]
public string UserName { get; set; }
[Required]
[DataType(DataType.Password)]
[Display(Name = "Password")]
public string Password { get; set; }
[Display(Name = "Remember me?")]
public bool RememberMe { get; set; }
}
Controller:
//
// GET: /My/Login
[AllowAnonymous]
public ActionResult Login(string returnUrl)
{
ViewBag.ReturnUrl = returnUrl;
return View();
}
//
// POST: /My/Login
[HttpPost]
[AllowAnonymous]
[ValidateAntiForgeryToken]
public async Task<ActionResult> Login(LoginViewModel model, string returnUrl)
{
if (ModelState.IsValid)
{
var user = await UserManager.FindAsync(model.UserName, model.Password);
if (user != null)
{
await SignInAsync(user, model.RememberMe);
return RedirectToLocal(returnUrl);
}
else
{
ModelState.AddModelError("", "Invalid account name or password.");
}
}
return View(model);
}
Page:
#using (Html.BeginForm("Login", "My", new { ReturnUrl = ViewBag.ReturnUrl }, FormMethod.Post, new { #class = "form-horizontal", role = "form" }))
{
#Html.AntiForgeryToken()
<hr />
#Html.ValidationSummary(false)
<div class="form-group">
<p class="col-md-2 control-label"><strong>Account</strong></p>
<div class="col-md-10">
#Html.TextBoxFor(m => m.UserName, new { #class = "form-control" })
#Html.ValidationMessageFor(m => m.UserName)
</div>
</div>
<div class="form-group">
#Html.LabelFor(m => m.Password, new { #class = "col-md-2 control-label" })
<div class="col-md-10">
#Html.PasswordFor(m => m.Password, new { #class = "form-control" })
#Html.ValidationMessageFor(m => m.Password)
</div>
</div>
<div class="form-group">
<div class="col-md-offset-2 col-md-10">
<div class="checkbox">
#Html.CheckBoxFor(m => m.RememberMe)
#Html.LabelFor(m => m.RememberMe)
</div>
</div>
</div>
<div class="form-group">
<div class="col-md-offset-2 col-md-10">
<input type="submit" value="Log in" class="btn btn-default" /> | #Html.ActionLink("Cancel", "Index", "Explore")
</div>
</div>
