表单身份验证:角色(MVC 4)C#

我正在尝试在我的应用程序中实现表单身份验证.我举了各种例子,看了一下这个论坛和ASP.net MVC中提供的示例和问题,但我无法让它工作.

我设法验证我的用户,但角色似乎不起作用:-(

我已经设置了我的Web.Config如下:

在我的控制器中,我将索引页面设置为AllowAnonymous,然后检查用户是否经过身份验证.如果没有,则重定向到登录页面..

[AllowAnonymous]
    public ActionResult Index(string sortOrder, string searchString,string currentFilter, int? page)
    {
        if (!Request.IsAuthenticated)
        {

            return RedirectToAction("Login", "Account");

        }
//Find all the employees
        var employees = from s in db.Employees
                       select s;
//Pass employees to the view (All works fine)
return View(employees.ToPagedList(pageNumber, pageSize));
}

这一切都在100%工作

我的登录代码如下所示:

 [HttpPost]
    [AllowAnonymous]
    [ValidateAntiForgeryToken]
    public ActionResult Login(User user, string returnUrl)
    {
        var myUser = db.Users.Where(b => b.UserName == user.UserName).FirstOrDefault();
        if(myUser != null)
        {
            if(myUser.Password==user.Password)
            {
                //These session values are just for demo purpose to show the user details on master page
                //Session["User"] = user;
                ICollection levels = db.UserAccessLevels.Where(b => b.UserId == myUser.UserId).ToList();
                //Session["levels"] = levels;

                //Let us now set the authentication cookie so that we can use that later.
                FormsAuthentication.SetAuthCookie(user.UserName, false);

                return RedirectToAction("Index","Employee");
            }
        }
        ViewBag.Message = "Invalid User name or Password.";
        return View(user);
    }

我在Global.asax文件中也有以下代码:

 protected void FormsAuthentication_OnAuthenticate(Object sender, FormsAuthenticationEventArgs e)
    {
        if (FormsAuthentication.CookiesSupported == true)
        {
            if (Request.Cookies[FormsAuthentication.FormsCookieName] != null)
            {
                try
                {
                    //let us take out the username now                
                    string username = FormsAuthentication.Decrypt(Request.Cookies[FormsAuthentication.FormsCookieName].Value).Name;
                    string roles = string.Empty;

                    using (TrainingContext entities = new TrainingContext())
                    {
                        User user = entities.Users.SingleOrDefault(u => u.UserName == username);

                        roles = "admin";//user.Roles;
                    }
                    //Let us set the Pricipal with our user specific details
                    e.User = new System.Security.Principal.GenericPrincipal(
                       new System.Security.Principal.GenericIdentity(username, "Forms"), roles.Split(';'));
                }
                catch (Exception)
                {
                    //somehting went wrong
                }
            }
        }
    }

当我登录我的FormsAuthentication_OnAuthenticate执行并且一切看起来都很好.我的用户已设置,我在会话中的角色也在那里......

但是,当我点击我的员工/索引屏幕的详细信息时,它会将我带回登录屏幕(我希望它能够将我带到我点击的员工的详细信息,因为我已登录并且我被设置为管理员角色)

请你协助我试着解决问题.我已经坐了18个多小时才试图解决这个问题.
