This fork upgrades the origin project to Rails 3.1.rc and OmniAuth 1.0-beta. I forked this projects because I wanted to integrate the new oa-identity gem, which is new in 1.0-beta. This gem provides traditional login/password registration and authentication.
Read the full article "Omniauth pure: Authentication with Facebook, Google, Google Apps, Twitter, Github, AOL, MyOpenID and many other OpenID providers" on CommunityGuides: http://www.communityguides.eu/articles/16
This article will demonstrate how to set up a multi-provider authentication using the fabulous OmniAuth gem. Users will be able to add multiple providers to their account and views for sign-in, sign-up and management of linked accounts are provided. The full source code is available on Github as a basis for your own projects.
