I have had similar problems

I could not figure out what was different between my app (I inherited from someone else) and the default sample code.

I discovered that my [Authorize] attribute was not being applied by the framework even when the rest of the user management stack was working.

I realised eventually that AuthorizeAttribute is an example of a Filter and that by adding it explicitly in the FilterConfig it started to be used as expected (even though it is not added by the default sample code):

public class FilterConfig
{
    public static void RegisterGlobalFilters(GlobalFilterCollection filters)
    {
        filters.Add(new HandleErrorAttribute());
        filters.Add(new AuthorizeAttribute());
    }
}

and everything as usual in the Application_Start method:

FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);

Edit:

Although this lets the basic Authorize attribute work, it leads to a problem where the framework isn't instantiating the attribute per-method call with the Roles property set. So I had to figure out what caused the problem. It was due to some Unity setup code:

var oldProvider = FilterProviders.Providers.Single(f => f is FilterAttributeFilterProvider);
FilterProviders.Providers.Remove(oldProvider);

Removing this (it was actually unused) fixed the issue, so I no longer needed FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters); either
