Question

What I want to do is a two-level role check on an action handler. For example, Require that the users is in at least one of the following groups: SysAdmins, Managers AND in at least one of the following groups: HR, Payroll, Executive.

Initial guess was that this might be the way to do this but I don’t think it is:

[Authorize(Role="SysAdmins,Managers")]
[Authorize(Role="HR,Payroll,Executive")]
public ActionResult SomeAction()
{
    [...]
}

Do I need to role my own custom Attribute to take in Role1 and Role2 or something like that? Or is there an easier/better way to do this?

You’ll need your own attribute. Here’s mine:

public class AuthorizationAttribute : ActionFilterAttribute
{
    public override void OnActionExecuting(ActionExecutingContext filterContext)
    {
        var portalModel = ContextCache<PortalModel>.Get(ContextCache.PortalModelSessionCache);

        var requestedController = filterContext.RouteData.GetRequiredString("controller");
        var requestedAction = filterContext.RouteData.GetRequiredString("action");

        var operation = string.Format("/{0}/{1}", requestedController, requestedAction);

        var authorizationService = IoC.Container.Resolve<IAuthorizationService>();

        if (!authorizationService.IsAllowed(AccountController.GetUserFromSession(), operation))
        {
            filterContext.Controller.ViewData["Message"] = string.Format("You are not authorized to perform operation: {0}", operation);
            filterContext.HttpContext.Response.Redirect("/Error/NoAccess");
        }
        else
        {
        }

    }

}
