Microsoft Graph OAuth2 Strategy for OmniAuth. Can be used to authenticate with Office365 or other MS services, and get a token for the Microsoft Graph Api, formerly the Office365 Unified Api.

Add this line to your application's Gemfile:

gem 'omniauth-microsoft_graph'

And then execute:

$ bundle

Or install it yourself as:

$ gem install omniauth-microsoft_graph

Register a new app in the Azure Portal / App registrations to get the AZURE_APPLICATION_CLIENT_ID and AZURE_APPLICATION_CLIENT_SECRET below.

Rails.application.config.middleware.use OmniAuth::Builder do
  provider :microsoft_graph, ENV['AZURE_APPLICATION_CLIENT_ID'], ENV['AZURE_APPLICATION_CLIENT_SECRET']
end

Just add {login_hint: "[email protected]"} to your url generation to form:

/auth/microsoft_graph?login_hint=email@example.com

This version requires OmniAuth v2. If you are using Rails, you will need to include or upgrade omniauth-rails_csrf_protection. If you upgrade and get an error in your logs complaining about "authenticity error" or similiar, make sure to do bundle update omniauth-rails_csrf_protection
