根据ASP.NET MVC 4 Internet应用程序登录中的用户角色重定向到其他页面

Question

I'm creating ASP.NET MVC 4 Internet Application. In that Application I created Login Page that any user can log, then I'm Trying to redirect user to different pages based on their role.

ASP.NET Identity is the membership system here.

In my AspNetRoles Table I have two roles:

Id| Name

1 | HEI_Admin

2 | HEI_User

This is my Login Controller method:

    [HttpPost]
    [AllowAnonymous]
    [ValidateAntiForgeryToken]
    public async Task<ActionResult> Login(LoginViewModel model, string returnUrl)
    {
        if (ModelState.IsValid)
        {
            var user = await UserManager.FindAsync(model.UserName, model.Password); 

            if (user != null)
            {
                if (user.ConfirmedEmail == true)
                {

                    await SignInAsync(user, model.RememberMe);

                    if (String.IsNullOrEmpty(returnUrl))
                    {
                        if (UserManager.IsInRole(user.Id, "HEC_Admin"))
                        {
                            return RedirectToAction("Index", "HEC");
                        }
                        //role Admin go to Admin page
                        if (UserManager.IsInRole(user.Id, "HEI_User"))
                        {
                            return RedirectToAction("Index", "HEI");
                        }
                    }

                    else
                    {
                        return RedirectToLocal(returnUrl);
                    }


                }
                else
                {
                    ModelState.AddModelError("", "Confirm Email Address.");
                }
            }
            else
            {
                ModelState.AddModelError("", "Invalid username or password.");
            }
        }
        // If we got this far, something failed, redisplay form
        return View(model);
    }

but when I try to log using correct credentials I'm getting following error:

A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections.

All the connection are double checked, how can achieve this problem.

        if (ModelState.IsValid)
        {
            var user = await UserManager.FindAsync(model.UserName, model.Password);
            if (user != null)
            {
                await SignInAsync(user, model.RememberMe);
                if (UserManager.IsInRole(user.Id, "Admin"))
                {
                    return RedirectToAction("Index", "Admin");
                }
                else if (UserManager.IsInRole(user.Id, "Clerk"))
                {
                    return RedirectToAction("Index","Employee");
                }
                else if (UserManager.IsInRole(user.Id, "Customer"))
                {
                    return RedirectToAction("Index", "Customer");
                }
                //return RedirectToLocal(returnUrl);
            }
            else
            {
                ModelState.AddModelError("","Invalid username or password");
            }
        }
        // If we got this far, something failed, redisplay form
        return View(model);
    }

This is the code i used for redirect. also see if the userID and RoleID are inserted into the ASPNETUserRoles table

if you are using any centralized database then Make sure your database engine is configured to accept remote connections.
