OpenSesame is a Warden strategy for providing "walled garden" authentication for access to Rack-based applications via Omniauth. The intent is protect the visibility of your app from the outside world. For example, your company has internal apps and/or staging enviroments for multiple projects and you want something better than HTTP basic auth.
Enter OpenSesame. To authenticate, OpenSesame currently uses Omniauth and the Github API to require that a user is both logged in to Github and a member of the Github organization for which OpenSesame is configured.
In your Gemfile:
$ gem "opensesame"
Register your application(s) with Github for OAuth access. For each application, you need a name, the site url, and a callback for OAuth. The OmniAuth-Github OAuth strategy used under the hood will expect the callback at mount path + '/github/callback'. So the development version of your client application might be registered as:
Name: MyApp - local URL: http://localhost:3000 Callback URL: http://localhost:3000/opensesame/github/callback
# Rails config/initializers/opensesame.rb require 'opensesame' OpenSesame.configure do |config| config.enable Rails.env.staging? config.github ENV['GITHUB_APP_ID'], ENV['GITHUB_SECRET'] config.organization 'challengepost' config.mounted_at '/opensesame' end
Mount OpenSesame in your Rails routes.rb:
# Rails config/routes.rb mount OpenSesame::Engine => OpenSesame.mount_prefix
Place the following into your appplication_contrrollerb.rb:
