Überauth Okta

Okta strategy for Überauth.

Installation

Add :ueberauth_okta to your list of dependencies in mix.exs:

def deps do
  [{:ueberauth_okta, "~> 0.2"}]
end

Add the strategy to your applications:

def application do
  [extra_applications: [:ueberauth_okta]]
end

Include the provider in your configuration for Ueberauth:

config :ueberauth, Ueberauth,
  providers: [
    okta: { Ueberauth.Strategy.Okta, [] }
  ]

You'll need to register a new application with Okta and get the client_id and client_secret. That setup is out of the scope of this library, but some notes to remember are:

• Ensure Authorization Code grant type is enabled
• You have valid Login Redirect Urls listed for the app that correctly reference your callback route(s)
• user and/or group permissions may need to be added to your Okta app before successfully authenticating

Then include the configuration for okta.

config :ueberauth, Ueberauth.Strategy.Okta.OAuth,
  client_id: System.get_env("OKTA_CLIENT_ID"),
  client_secret: System.get_env("OKTA_CLIENT_SECRET"),
  site: "https://your-doman.okta.com"

If you haven't already, create a pipeline and setup routes for your callback handler

pipeline :auth do
  plug Ueberauth
end
scope "/auth" do
  pipe_through [:browser, :auth]
  get "/:provider/callback", AuthController, :callback
end

Create an endpoint for the callback where you will handle the Ueberauth.Auth struct

defmodule MyApp.AuthController do
  use MyApp.Web, :controller
  def callback_phase(%{ assigns: %{ ueberauth_failure: fails } } = conn, _params) do
    # do things with the failure
  end
  def callback_phase(%{ assigns: %{ ueberauth_auth: auth } } = conn, params) do
    # do things with the auth
  end
end

Goals

This is just the start ueberauth_okta strategy for support with Okta auth protocols. Initially, I will mainly be focused on Okta OAuth, but once that is up I will move onto other autentication routes I'd also like to support (see below):

• OAuth 2.0
• SAML
