This gem contains the OmniAuth AOL strategy that allows authentication with AOL Instant Messenger (AIM)/AOL Mail credentials.
In Rails add the gem to your Gemfile:
gem "omniauth-aol"
Add the following to your config/initializers/omniauth.rb:
provider :aol, ENV['AOL_KEY'], ENV['AOL_SECRET'], :scope => 'email'
Get your AOL_KEY and AOL_SECRET from dev.aol.com or by emailing identitysupport@teamaol.com. Put these values in application.rb.
Visit the following URL to make sure it works
http://localhost:3000/auth/aol
