OmniAuth Clever

Unofficial OmniAuth strategy for Clever SSO OAuth2 integration.

Installation

Add the gem to your application's Gemfile:

gem 'omniauth-clever', '~> 2.0.0'

And then execute:

$ bundle

Usage

OmniAuth Clever is Rack Middleware in the OmniAuth convention. See the OmniAuth 1.0 docs for more information.

Follow the Clever OAuth docs to register your application, set callback URLs, and get a client ID and client secret.

Example: In config/initializers/omniauth.rb, do:

Rails.application.config.middleware.use OmniAuth::Builder do
  provider :clever, ENV['CLEVER_CLIENT_ID'], ENV['CLEVER_CLIENT_SECRET']
end

Clever is a unique OAuth 2.0 service provider in that login sequences are often initiated by Clever, not the client. When Clever initiates login, a state parameter is not relevant nor sent.

Configuring

To be able to set the optional district_id parameter on a per-request basis, passing this params to your /auth/clever url, use this in the initializer instead:

Rails.application.config.middleware.use OmniAuth::Builder do
  provider :clever, ENV['CLEVER_CLIENT_ID'], ENV['CLEVER_CLIENT_SECRET'],
           :setup => lambda { |env|
             params = Rack::Utils.parse_query(env['QUERY_STRING'])
             env['omniauth.strategy'].options[:client_options][:district_id] = params['district_id']
           }
end

Testing

This strategy can be and has been tested with the omniauth-test-harness.
