OmniAuth: Flexible, Unassuming Multi-Provider Authentication for Rack - Intridea Blog. The web application landscape has changed drastically in the past year or two.
Where once every site was a silo unto itself and could reasonably expect users to create a unique login and password for each site, it is now a different story. I sigh every time I have to fill out yet another registration form, wishing instead for a simple "Connect with Facebook", "Sign in with Twitter", or "Log in with OpenID". At the same time, services are more interconnected than ever. One of the best ways to increase the popularity and viability of a new service is by piggybacking it onto the existing user bases of apps such as Twitter, Facebook, and Foursquare.
There are lots of authentication solutions out there for Rails. OmniAuth: The Unassuming Authentication Library Today is the public release of OmniAuth. What does this mean for you? Installation OmniAuth is available as a gem: gem install omniauth Diving In Using OmniAuth is as simple as using any other Rack middleware. That's it! Federated ID, OpenID, and OAuth: A Web Authentication Primer. Federated ID Federated ID, also called Federated Identity Management (FIM), allows a Service Provider (SP) to offer a service without implementing its own authentication system, and to instead trust another entity—an Identity Provider (IdP)—to provide authenticated users to them.
If that seems confusing, imagine two companies: IdentiCorp and ServiceInc. ServiceInc has great services, but they don’t like the idea of managing passwords for users. IdentiCorp, on the other hand, provides username and password management as their main business. So these two companies come to an agreement—ServiceInc will allow people to log in to their websites using IdentiCorp credentials. Technology The technology used to implement this functionality is XML-based, with two options being presented to implementers. OpenID Rather than being something completely separate, OpenID is just one type of Federated Identity system. How It Works Here are a few of the main benefits of OpenID: Overlap of identity technologies - Google OAuth & Federated Login Research. Here is a diagram of how the flow could work: Here is a more detailed description of the steps.Tom arrives for work one day, and before he logs into the corporate SSO system, he decides to setup a LinkedIn account using his firstname.lastname@example.org E-mail address and providing a password that he wanted to use for the account.
(In Example 2 below we talk about this step could be optimized in the future)During the setup process, he provides his E-mail address to LinkedIn, and the LinkedIn servers make an inquiry in the background using XRDS to ask AlertBlue's servers if they support the Portable Contacts standard, and they respond with a yes. (This discovery step is invisible to Tom)Tom is then redirected via the OAuth protocol to the server that AlertBlue specified via XRDS that supports PortableContacts for their domain. Since AlertBlue has outsourced E-mail (and contact lists) to Google, the XRDS file actually points to Google's servers, so Tom is redirected there. Paul Madsen, NTT. OAuth 2. Last year I showed how to use pecl/oauth to write a Twitter OAuth Consumer.
But what about writing the other end of that? What if you need to provide OAuth access to an API for your site? How do you do it? Luckily John Jawed and Tjerk have put quite a bit of work into pecl/oauth lately and we now have full provider support in the extension. Introducing OAuth 2.0 by hueniverse. Two weeks ago, the IETF OAuth Working Group published the first draft of the OAuth 2.0 protocol.
OAuth is a security protocol that enables users to grant third-party access to their web resources without sharing their passwords. OAuth 1.0 was published in December 2007 and quickly become the industry standard for web-based access delegation. A minor revision (OAuth 1.0 Revision A) was published in June 2008 to fix a security hole. In April 2010, OAuth 1.0 was published as RFC 5849. OAuth 2.0 is a completely new protocol and is not backwards compatible with previous versions. Many luxury cars come with a valet key. The new draft represents a yearlong discussion around goals and requirements for the protocol with participants from a wide range of companies including Yahoo! Why a New Version? OAuth 1.0 was largely based on two existing proprietary protocols: Flickr’s API Auth and Google’s AuthSub.
