A plug to authenticate using Cassette

When plugged, this will test the session for the presence of the user. When not present it will test for presence of a ticket parameter and validate it. If none of those are present, it will redirect the user to the cas login.

To add to your router:

defmodule Router do
  use Plug.Router

  plug Cassette.Plug

  plug :match
  plug :dispatch

  (...)
end

Just be sure that your Plug.Session is configured and plugged before Cassette.Plug

If you are using this with phoenix, plug into one of your pipelines:

defmodule MyApp.Router do
  use MyApp.Web, :router

  pipeline :browser do
    (...)
    plug :fetch_session
    plug Cassette.Plug
    plug :fetch_flash
    (...)
  end
end

Be sure that is module is plugged after the :fetch_session plug since this is a requirement

Customizing behaviour

The behaviour for authentication failures may be customized using your own Cassette.Plug.AuthenticationHandler. Please refer to the documentation on that module for more details.
