MVC 5 login custom DB

Question

I'm switching from mvc 3 to mvc 5, I know they changed the authentication in .Net 4.5.1 (OWIN authentication).

all I need it to log in the website so the Request.IsAuthenticated is true, I don't want the membership of Microsoft, I want to use my database.

What I tried is not working even this

var claims = new List<Claim>();
claims.Add(new Claim(ClaimTypes.Name, "Name"));
claims.Add(new Claim(ClaimTypes.Email, "mail@mail.com"));
var identity = new ClaimsIdentity(claims, DefaultAuthenticationTypes.ApplicationCookie);

var ctx = HttpContext.GetOwinContext();
var authenticationManager = ctx.Authentication;
authenticationManager.SignIn(identity);

I really don't know what to do but I want to be logged in the system using my own database, the has only username and password

Try this, I hope it will help you.

    [AllowAnonymous]
    public ActionResult Login(string returnUrl)
    {
        ViewBag.ReturnUrl = returnUrl;
        return View();
    }

    [HttpPost]
    [AllowAnonymous]
    [ValidateAntiForgeryToken]
    public async Task<ActionResult> Login(LoginViewModel model, string returnUrl)
    {
        if (ModelState.IsValid)
        {
            var user = MyViewModels.checkUser(model.UserName, model.Password);
            if (user!=null)
            {
                SignInAsync();
                return RedirectToAction("Welcome");
            }
            else
            {
                ModelState.AddModelError("", "Invalid username or password.");
            }
        }
        return View(model);
    }

    private void SignInAsync()
    {
        var claims = new List<Claim>();
        claims.Add(new Claim(ClaimTypes.Name, "UserName"));
        claims.Add(new Claim(ClaimTypes.Email, "User@mail.com"));
        var id = new ClaimsIdentity(claims,
                                    DefaultAuthenticationTypes.ApplicationCookie);

        var ctx = Request.GetOwinContext();
        var authenticationManager = ctx.Authentication;
        authenticationManager.SignIn(id);
    }

    [Authorize]
    public ActionResult Welcome()
    {
        return View();
    }

If you add [Authorize] attribute in the action, then it will redirect only the user name and password is authorize

Function to get user name and password from database

    public static UserTable checkUser(string userName, string password)
    {
        DemoEntities db = new DemoEntities();
        var query = (from u in db.UserTables
                     where u.UserName == userName && u.Password == password
                     select u).FirstOrDefault();
        if(query!=null)
            return query;
        else
            return null;
    }

Look at this post to see how set up a bare bones OWIN authentication with your own membership system.
