OmniAuth::OpenIDConnect

Originally was omniauth-openid-connect

I've forked this repository and launch as separate gem because maintaining of original was dropped.

Installation

Add this line to your application's Gemfile:

gem 'omniauth_openid_connect'

And then execute:

$ bundle

Or install it yourself as:

$ gem install omniauth_openid_connect

Usage

Example configuration

config.omniauth :openid_connect, {
  name: :my_provider,
  scope: [:openid, :email, :profile, :address],
  response_type: :code,
  client_options: {
    port: 443,
    scheme: "https",
    host: "myprovider.com",
    identifier: ENV["OP_CLIENT_ID"],
    secret: ENV["OP_SECRET_KEY"],
    redirect_uri: "http://myapp.com/users/auth/openid_connect/callback",
  },
}

Configuration details:

• name is arbitrary, I recommend using the name of your provider. The name configuration exists because you could be using multiple OpenID Connect providers in a single app.
• Although response_type is an available option, currently, only :code is valid. There are plans to bring in implicit flow and hybrid flow at some point, but it hasn't come up yet for me. Those flows aren't best practive for server side web apps anyway and are designed more for native/mobile apps.
• If you want to pass state paramete by yourself. You can set Proc Object. e.g. state: Proc.new{ SecureRandom.hex(32) }
• nonce is optional. If don't want to pass "nonce" parameter to provider, You should specify false to send_nonce option. (default true)
• Support for other client authentication methods. If don't specified :client_auth_method option, automatically set :basic.
• Use "OpenID Connect Discovery", You should specify true to discovery option. (default false)
• In "OpenID Connect Discovery", generally provider should have Webfinger endpoint. If provider does not have Webfinger endpoint, You can specify "Issuer" to option. e.g. issuer: "https://myprovider.com" It means to get configuration from "https://myprovider.com/.well-known/openid-configuration".
