使用OWIN Cookies身份验证登录后，User.Identity.IsAuthenticated不是True-ASP.NET WebForms

Question

用户登录时遇到问题：

 private void Awake()
{
    if (Instance == null)
        Instance = this;
    else
        Destroy(gameObject);
    DontDestroyOnLoad(gameObject);
    interstitialAd = new InterstitialAd(InterstitialAdId);

    Showbanner(); // <------- Here
    requestAds();

    interstitialAd.LoadAd(request);
}

，然后在我的主页的Init中运行以下命令：

Dim manager = Context.GetOwinContext().GetUserManager(Of ApplicationUserManager)()
Dim signinManager = Context.GetOwinContext().GetUserManager(Of ApplicationSignInManager)()

'this session is for the whole issue of browser not getting the cookies'
HttpContext.Current.Session("RunSession") = "1"
Dim result = signinManager.PasswordSignIn(Email.Text, Password.Text, RememberMe.Checked, shouldLockout:=False)

由于某种原因，用户每次成功登录后都会不断重定向到登录屏幕。是否需要用其他东西代替Authenticated？
