c# - ASP.NET 5 Authorize against two or more policies (OR-combined policy)

Question

Is it possible to apply authorization against two or more policies? I am using ASP.NET 5, rc1.

[Authorize(Policy = "Limited,Full")]
public class FooBarController : Controller
{
    // This code doesn't work
}

If not, how may I achieve this without using policies? There are two groups of users that may access this controller: "Full" and "Limited". Users may either belong to "Full" or "Limited", or both. They only require to belong to one of the two groups in order to access this controller.

Answer 1

Not the way you want; policies are designed to be cumulative. For example if you use two separate attributes then they must both pass.

You have to evaluate OR conditions within a single policy. But you don't have to code it as ORs within a single handler. You can have a requirement which has more than one handler. If either of the handlers flag success then the requirement is fulfilled. See Step 6 in my Authorization Workshop.
