Hi Fahad,

You can copy UmbLoginController from Umbraco source code, that's it:

public class LoginController : SurfaceController
{
    [HttpPost]
    public ActionResult HandleLogin([Bind(Prefix = "loginModel")]LoginModel model)
    {
        if (ModelState.IsValid == false)
        {
            return CurrentUmbracoPage();
        }

        if (Members.Login(model.Username, model.Password) == false)
        {
            //don't add a field level error, just model level
            ModelState.AddModelError("loginModel", "Invalid username or password");
            return CurrentUmbracoPage();
        }

        TempData["LoginSuccess"] = true;

        //if there is a specified path to redirect to then use it
        if (model.RedirectUrl.IsNullOrWhiteSpace() == false)
        {
            return Redirect(model.RedirectUrl);
        }

        //redirect to current page by default

        return RedirectToCurrentUmbracoPage();
        //return RedirectToCurrentUmbracoUrl();
    }
}

Just paste this controller to your solution and continue to work with it.

Thanks,

Alex
