This is the client that uses ONLY omniauth to connect to a custom provider for single sign on between multiple applications.
git clone git://github.com/joshsoftware/sso-devise-omniauth-client.git bundle install rake db:create rake db:migrate
On the Provider, register this client application:
rails c > @client = Client.new > @client.app_id = 'some key' > @client.app_secret = 'some secret' > @client.save
Copy these same values in the Client config/initializers/omniauth.rb
APP_ID = 'some key' APP_SECRET = 'some secret' # Update your custom Omniauth provider URL here CUSTOM_PROVIDER_URL = 'http://localhost:3000' Rails.application.config.middleware.use OmniAuth::Builder do provider :josh_id, APP_ID, APP_SECRET end
Since we want a single sign-on between our server and our client apps, we need to write a custom omniauth strategy. This is written in lib/josh_id.rb. Please implement your own and / or modify as required.
git clone git://github.com/joshsoftware/sso-devise-omniauth-client.git client1 git clone git://github.com/joshsoftware/sso-devise-omniauth-client.git client2 # configure the client1 key and secret in the provider as mentioned above # In separater terminals start 2 clients client1 $ rails s -p3001 client2 $ rails s -p3002
Now, if you login via 1 client, and change the URL to the other, you will be automatically signed-in!
Please feel free to enhance this demo. For any doubts, please send an email to firstname.lastname@example.org
I am eager to write some rspec for this setup. If you do, please send me a pull request!
