How to use login in different areas on Asp.net mvc

Question

I’m creating an app, where it has more than one Area, which is restricted. (as shown in the image below).

My question is how to login in different areas?

Details:

As users of the Admin area and the System area are distinct, each one is saved in a different table in the database.

Authentication is performed with Forms, and authentication to the Admin area already exists:

<authentication mode="Forms">
      <forms loginUrl="~/Autenticacao/Login" defaultUrl="Admin/Home" timeout="2880" />
    </authentication>

Answer 1

In his Web.config, withdraw the part defaultUrl="Admin/Home".

<authentication mode="Forms">
      <forms loginUrl="~/Autenticacao/Login" timeout="2880" />
</authentication>

In action Autenticacao/Login, you can redirect users to different locations, something like:

public ActionResult Login(String LoginStr, String SenhaStr, bool ManterConectado)
{
    // Seu código de login
    return RedirectPaginaInicial(usuario);
}

// Função para retornar a página inicial de cada usuário
private RedirectToRouteResult RedirectPaginaInicial(Usuario usuario)
{
     if (usuario.Areas == (int)PaginaPrincipal.ADMIN)
         return RedirectToAction("Lista", "PaginaAdministrador");

     if (usuario.Areas == (int)PaginaPrincipal.SISTEMA)
          return RedirectToAction("Lista", "Sistema");

     return RedirectToAction("Lista", "Agenda");
}

In that case, PaginaPrincipal is a enum:

public enum PaginaPrincipal
{
     [Display(ResourceType = typeof(Translate.Enum), Name = "Administrador")]
     ADMIN = 1,

     [Display(ResourceType = typeof(Translate.Enum), Name = "Sistema")]
     SISTEMA = 2,
}

If you don’t just want a redirect, as the Gypsy comment, has this article "How to Use Areas in ASP.NET MVC 5?", explaining the step by step procedure to use the login by areas, is quite complete.

To make the answer more complete, I removed these excerpts from the article. You will have to include a new @Html.ActionLink

<li>@Html.ActionLink("ADMIN", "Index", "Home", new { area = "Admin" }, null)</li>
<li>@Html.ActionLink("SISTEMA", "Index", "Home", new { area = "Sistema" }, null)</li>

And insert the attribute [Authorize] above the name of HomeController:

[Authorize]
public class HomeController : Controller
{
    // GET: Admin/Home
    public ActionResult Index()
    {
        return View();
    }
}

Open the page _Layout.cshtml in Areas/Admin/Views/Shared and add the lines of div that shows the name of the logged in user, just below the menu "Application name".

@Html.ActionLink("Application name", "Index", "Home", new { area = "" }, new { @class = "navbar-brand" })
<div class="text-info">
    @User.Identity.Name
</div>
