Central Authentication Service strategy for Überauth.
-
Add
ueberauth
andueberauth_cas
to your list of dependencies inmix.exs
:def deps do [ {:ueberauth, "~> 0.2"}, {:ueberauth_cas, "~> 2.0.0"} ] end
-
Ensure
ueberauth_cas
is started before your application:def application do [applications: [:ueberauth_cas]] end
-
Configure the CAS integration in
config/config.exs
:config :ueberauth, Ueberauth, providers: [cas: {Ueberauth.Strategy.CAS, [ base_url: "http://cas.example.com", callback: "http://your-app.example.com/auth/cas/callback", ]}]
-
Include the Überauth plug in your controller:
defmodule MyApp.AuthController do use MyApp.Web, :controller plug Ueberauth ... end
-
Create the request and callback routes if you haven't already:
scope "/auth", MyApp do pipe_through :browser get "/:provider", AuthController, :request get "/:provider/callback", AuthController, :callback end
-
Your controller needs to implement callbacks to deal with
Ueberauth.Auth
andUeberauth.Failure
responses.
Überauth CAS was tested with the Casino CAS server implementation. Please let me know if Überauth CAS is incompatible with your CAS server, and why.
The docs contain more information about protocol specifics.
