Komondor

A helper gem to add single-sign-on to rails apps.

Installation

Add this line to your application's Gemfile:

gem 'komondor'

And then execute:

$ bundle

Then run the installer

$ rails g komondor:install

Then run migrations

$ rake db:migrate

Basic Usage

We use 3 environment variables in each connected app

SSO_SECRET_KEY=the secret key of the app
SSO_URL=the domain of the auth provider
SSO_NAME=the name of the auth provider

For any controllers you wish to protect, you need to add a before filter

# For Rails 3
before_filter :guard_dog

# For Rails 4
before_action :guard_dog

Advanced Usage

Top Bar

By default this gem adds a topbar to your page that will add links to all apps the signed in user has the ability to access. Once installed, you can edit the style of the top bar with the komondor.css.scss file added to app/assets/stylesheets.

If you don't want to use the top bar, you can remove the folllowing lines from their respective files:

app/assets/javascripts/application.js

//= require komondor

app/views/layouts/application.html.erb

<script>Komondor = { identity_id: <%= current_user.identity_id %> };</script>

And delete the stylesheet: komondor.css.scss

Without the topbar you will need to add a signout link:

<%= link_to "Signout", sessions_path, method: :delete %>
