SAML (Security Assertion Markup Language) is the OASIS standard [1] for  
representing user authentication, entitlement, and attribute information  
in XML. Its most common use is to support cross-domain/federated web  
single sign-on (SSO).

Now in version 2.0, SAML is widely supported in enterprise access  
management products [2,3] and open source projects [4,5,6,7], but has  
only recently made the jump to dynamic languages such as PHP [8] and,  
now, Ruby. The OpenSSO project recently announced SAML 2.0 for Ruby  
(saml2ruby) as an OpenSSO Extension [9]. The saml2ruby code, kindly  
contributed by Todd Saxton, is in early, but functional form - informal  
tests show that it successfully interoperates with Sun Java System  
Access Manager [10].

If you’re working on a Ruby/Rails app and someone has mentioned SSO or  
SAML, this should help you out. There is a sample Rails app that shows  
how to get SAML-enabled with a minimum of fuss. And, need I mention it,  
contributors are always welcome…

Cheers,

Pat

P.S. Apologies for the large number of footnotes. It seemed like some  
amount of context was necessary…
