Role base Authentication in MVC

Question

I am creating role base authentication with User and UserRole Table. But my login page redirect again and again. I can see 302 error in Inspect element utility.

 

Below are source code 

MyAccount Controller

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using System.Web.Security;
using EasyApp.Models;

namespace EasyApp.Controllers
{
    public class MyAccountController : Controller
    {
        // GET: MyAccount
        [AllowAnonymous]
        public ActionResult Login()
        {
            return View();
        }

        [AllowAnonymous]
        [HttpPost]
        [ValidateAntiForgeryToken]

        public ActionResult Login(Login l, string ReturnUrl = "")
        {
            using (LPDBContext dc = new LPDBContext())
            {
                var user = dc.Users.Where(a => a.Username.Equals(l.Username) && a.Password.Equals(l.Password)).FirstOrDefault();
                if (user != null)
                {
                    FormsAuthentication.SetAuthCookie(user.Username, false);
                    if (Url.IsLocalUrl(ReturnUrl))
                    {
                        return Redirect(ReturnUrl);
                    }

                }
                ModelState.AddModelError("UserName", "username or password is incorrect !");
                ModelState.Remove("Password");
                return View();
            }


        }


        [Authorize]
    public ActionResult Logout()
    {
        FormsAuthentication.SignOut();
        return RedirectToAction("Index", "Main");
    }
}
    }

Main Controller

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;

namespace EasyApp.Controllers
{
    [Authorize]
    public class MainController : Controller
    {
        // GET: Main
        [AllowAnonymous]
        public ActionResult Index()
        {
            return View();
        }
        [Authorize]
        public ActionResult EDPDashboard()
        {
            return View();
        }

        [Authorize(Roles ="Admin")]
        public ActionResult DPDashboard()
        {
            return View();
        }

        [Authorize(Roles = "Admin")]
        public ActionResult RTFlim()
        {
            return View();
        }
    }
}
