Cannot login on ASP.NET Identity site

Question

I am developing a new ASP.NET MVC Core 2.0 and I'm using ASP.NET Identity for the membership system of the site. However, I cannot log in the user even though my SignInManager returns SignInStatus.Success after the signin attempt.

Here is my controller code for the login function:

public async Task<IActionResult> Login(LoginViewModel model)
    {
        var user = _db.Users.Where(x => x.Email == model.Email).FirstOrDefault();

        if (!ModelState.IsValid)
            return View();

        var result = await _signinManager.PasswordSignInAsync(
            model.Email, model.Password,
            model.RememberMe, false
            );

        if (!result.Succeeded)
        {
            ModelState.AddModelError("", "Login error");
            return View();
        }

        if (user.Role == "Admin")
        {
            return RedirectToAction("Users");
        }

        return RedirectToAction("Account");
    }

Ensure you have Identity services and middleware is setup in Startup.cs file.

Ensure you have app.UseAuthentication in Configure method. And Cookie based authentication is setup in ConfigureServices method using services.ConfigureApplicationCookie
