Überauth CAS Strategy

Central Authentication Service strategy for Überauth.

Installation

1. Add ueberauth and ueberauth_cas to your list of dependencies in mix.exs:

```elixir
def deps do
  [
    {:ueberauth, "~> 0.2"},
    {:ueberauth_cas, "~> 1.0.0"},
  ]
end
```

2. Ensure ueberauth_cas is started before your application:

```elixir
def application do
  [applications: [:ueberauth_cas]]
end
```

3. Configure the CAS integration in config/config.exs:

```elixir
config :ueberauth, Ueberauth,
  providers: [cas: {Ueberauth.Strategy.CAS, [
    base_url: "http://cas.example.com",
    callback: "http://your-app.example.com/auth/cas/callback",
  ]}]
```

4. In AuthController use the CAS strategy in your login/4 function:

```elixir
def login(conn, _params, _current_user, _claims) do
  conn
  |> Ueberauth.Strategy.CAS.handle_request!
end
```

Compatibility

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.
