Example
First choose your auth strategy and add it to your Gemfile. You can find a list of strategies here: https://github.com/intridea/omniauth/wiki/List-of-Strategies
gem 'omniauth-github', :github => 'intridea/omniauth-github'
gem 'omniauth-openid', :github => 'intridea/omniauth-openid'
You can add this to your rails middleware like so:
Rails.application.config.middleware.use OmniAuth::Builder do
require 'openid/store/filesystem'
provider :github, ENV['GITHUB_KEY'], ENV['GITHUB_SECRET']
provider :openid, :store => OpenID::Store::Filesystem.new('/tmp')
end
By default, OmniAuth will add /auth/:provider to your routes and you can start by using these paths.
By default, if there is a failure, omniauth will redirect to /auth/failure
