Request.IsAuthenticated Return False all the time

Question

I am having an issue with my Request.IsAuthenticated always return false. I am setting the AuthCookie

 CurrentRequest currentRequest = null;

            if (Url.IsLocalUrl(returnUrl) && returnUrl.Length > 1 && returnUrl.StartsWith("/")
                && !returnUrl.StartsWith("//") && !returnUrl.StartsWith("/\\"))
            {
                return Redirect(returnUrl);
            } else if (login.ValidateUser(acct.UserName, acct.Password))
            {
FormsAuthentication.SetAuthCookie(acct.UserName, true); //Edit on 11/12 @11:08
                currentRequest = new CurrentRequest();
                SessionWrapper.currentRequest = currentRequest;
                return RedirectToAction("About", "Home");
            }

//This is a partial login page that is supposed to display login or Logoff.

@using KMSS.Helper;

// this is always false

    @if (Request.IsAuthenticated) //Same issue with User.Identity.IsAuthenticated
    {
        if (SessionWrapper.currentRequest != null)
        {
            <text> Welcome <strong> @SessionWrapper.currentRequest.Username </strong>
                [@Html.ActionLink("Sign Off", "Logoff", "Account")]
            </text>
        } else {
           @: [ @Html.ActionLink("Sign In", "Login", "Account") ]
        }
    } else
    {

       @:[ @Html.ActionLink("Sign In", "Login", "Account") ]
  }

After reading online, I created a class with a bool value and tries to use that class instead. However, I am getting the object is not set to instance of a new variable exception. Here is how I had it set up: //Partial Login page

@model KMSS.Helper.ViewModelAuthenticate;

// this is always false

    @if (Model.IsAuthenticated) 
//The model is null even though I create create a reference in the Login Method i.e.     
(ViewModelAuthenticate auth = new ViewModelAuthenticate();
    {
        if (SessionWrapper.currentRequest != null)
        {
            <text> Welcome <strong> @SessionWrapper.currentRequest.Username </strong>
                [@Html.ActionLink("Sign Off", "Logoff", "Account")]
            </text>
        } else {
           @: [ @Html.ActionLink("Sign In", "Login", "Account") ]
        }
    } else
    {

       @:[ @Html.ActionLink("Sign In", "Login", "Account") ]
  }

//Here is the class public class ViewModelAuthenticate { public bool IsAuthenticate { get; set; } }

//Here is where I am initializing the class in the controller

 public ActionResult Login()
        {
           ViewModelAuthenticate auth = new ViewModelAuthenticate();
            auth.IsAuthenticate = false;
            return View();
        }

//I tried this inside and outside of Login, and it is called before the partial login view. However, I am still getting the object is not set to instance of a new variable exception. What am I doing wrong here? Your help will be appreciated.

I replaced my authentication section with this sample that a sample that I found here. It is working now.
