OmniAuth::OpenIDConnect

OpenID Connect strategy for OmniAuth

This is derrived work from jjbohn/omniauth-openid-connect which appears to be abandoned at this point. I have continued to merge PR's placed against that repo. But I have added enough of my own changes that it is diverged enough to re-release. @ThinkThroughMath actively utilizes this strategy and we will do our best to maintain it.

• Using Addressable 2.2.8 - In 2.3+ addressable decided that the way that Rails 3 handles param[] items was too hard to handle and removed the feature. This breaking change within a semantic version makes using addressable > 2.3 difficult in existing applications. There is no impact on the auth strategy though.
• Better devise support be returning a default name options parameter
• Partial integration of google nonce requirement.
• Inclusing of aging PRs from the parent gem this replaces.

Add this line to your application's Gemfile:

gem 'omniauth-openid-reconnect'

And then execute:

$ bundle

Or install it yourself as:

$ gem install omniauth-openid-reconnect

Example configuration

config.omniauth :openid_connect, {
  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 an optional requirement as of omniauth-1.2 but it does have an effect with dealing with devise and is the base for which devise uses to create routes identified with devise_for. The default is set to the expected camelization of openid_connect. If you need to override it you can pass the name parameter to the config hash. Be aware that what you set this to will be the provider for your devise routes.
• 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.
