OmniAuth::Decidim

This is the Microsoft/Azure ActiveDirectory (v2) strategy for login into Decidim using OmniAuth (SSO).

Add this line to your application's Gemfile:

gem 'decidim-microsoft'

And then execute:

bundle

Extracted from the initial instructions explained here:

https://medium.com/committed-engineers/setup-azure-ad-oauth-2-0-with-ruby-on-rails-and-devise-39848e3ed532

1. Go to your Azure account, configure a new tenant if you don't have any.

2. Register a new app n your tenant Azure Active Directory:

3. Use https://example.org/users/auth/azure_activedirectory_v2/callback as the callback URI (change example.org for your own domain)

4. Generate a new client ID/Secret in "Certificates & secrets"

5. Use the Application (client) ID, Directory (tentant) ID and the Secret ID to define the ENV variables.

6. Happy login!

By default, this strategy can be automatically configure using just these ENV vars:

AZURE_CLIENT_ID=XXXX
AZURE_TENANT_ID=XXXX
AZURE_CLIENT_SECRET=XXXX

By setting the ENV var AZURE_CLIENT_ID to value that's not empty, the "login with microsoft" button will appear automatically in you Decidim instance.

You can also customize the way you extract these secrets by creating a initializer file, such as:

# config/initializers/microsoft_omniauth.rb

Decidim::Microsoft.configure do |config|
  config.omniauth = {
    enabled: Rails.application.secrets.dig(:omniauth, :microsoft, :enabled),
    client_id: Rails.application.secrets.dig(:omniauth, :microsoft, :client_id:),
    tenant_id: Rails.application.secrets.dig(:omniauth, :microsoft, :tenant_id),
    client_secret: Rails.application.secrets.dig(:omniauth, :microsoft, :client_secret),
    icon_path: Rails.application.secrets.dig(:omniauth, :microsoft, :icon_path), # be aware of webpacker, must by media/images/something
    # optional variables:
    # See https://github.com/RIPAGlobal/omniauth-azure-activedirectory-v2/blob/master/lib/omniauth/strategies/azure_activedirectory_v2.rb
    scope: Rails.application.secrets.dig(:omniauth, :microsoft, :scope),
    base_azure_url: Rails.application.secrets.dig(:omniauth, :microsoft, :base_azure_url),
    authorize_params: Rails.application.secrets.dig(:omniauth, :microsoft, :authorize_params),
    domain_hint: Rails.application.secrets.dig(:omniauth, :microsoft, :domain_hint)
  }
end

And, of course, having these values in your config/secrets.yml file.

Bug reports and pull requests are welcome on GitHub at https://github.com/openpoke/decidim-module-microsoft.

To start contributing to this project, first:

• Install the basic dependencies (such as Ruby and PostgreSQL)
• Clone this repository

Decidim's main repository also provides a Docker configuration file if you prefer to use Docker instead of installing the dependencies locally on your machine.

You can create the development app by running the following commands after cloning this project:

$ bundle
$ DATABASE_USERNAME=<username> DATABASE_PASSWORD=<password> bundle exec rake development_app

Note that the database user has to have rights to create and drop a database in order to create the dummy test app database.

Then to test how the module works in Decidim, start the development server:

$ cd development_app
$ DATABASE_USERNAME=<username> DATABASE_PASSWORD=<password> bundle exec rails s

In case you are using rbenv and have the rbenv-vars plugin installed for it, you can add the environment variables to the root directory of the project in a file named .rbenv-vars. If these are defined for the environment, you can omit defining these in the commands shown above.

Please follow the code styling defined by the different linters that ensure we are all talking with the same language collaborating on the same project. This project is set to follow the same rules that Decidim itself follows.

Rubocop linter is used for the Ruby language.

You can run the code styling checks by running the following commands from the console:

$ bundle exec rubocop

To ease up following the style guide, you should install the plugin to your favorite editor, such as:

• Atom - linter-rubocop
• Sublime Text - Sublime RuboCop
• Visual Studio Code - Rubocop for Visual Studio Code

To run the tests run the following in the gem development path:

$ bundle
$ DATABASE_USERNAME=<username> DATABASE_PASSWORD=<password> bundle exec rake test_app
$ DATABASE_USERNAME=<username> DATABASE_PASSWORD=<password> bundle exec rspec

Note that the database user has to have rights to create and drop a database in order to create the dummy test app database.

In case you are using rbenv and have the rbenv-vars plugin installed for it, you can add these environment variables to the root directory of the project in a file named .rbenv-vars. In this case, you can omit defining these in the commands shown above.

If you want to generate the code coverage report for the tests, you can use the SIMPLECOV=1 environment variable in the rspec command as follows:

$ SIMPLECOV=1 bundle exec rspec

This will generate a folder named coverage in the project root which contains the code coverage report.
