ASP MVC Authorize Error

Question

When I Use :

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

OR

[Authorize(Users="john")]
public ActionResult Index() {
    ....
    return View();
}

My Script Working Well But When I Use :

[Authorize(Roles="Admin")]
public ActionResult Index() {
    .....
    return View();
}

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. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified).

You have a sql server connection problem. not related to Authorize. — DarthVader

I found a solution. In my web.config:

1.<modules>
2.<remove name="FormsAuthenticationModule" />
3.<remove name="RoleManager" />
4.</modules>

I added the line 3, and the new AspNet.Identity code took over allowing me to use User.IsInRole(..)

It helped me a lot, thanks. Do you know why is this required? I downloaded the sample for Identity from NuGet and there is no such code in Web.config.
