RoR integration with Siteminder?


I’m new to RoR and am wondering what has to be done to incorporate SSO with Siteminder with a web application?

I know that with Spring there is a built-in ability to connect security with Siteminder, so I’d like to know how RoR deals with security and Siteminder.



At my company I have it set up via an apache module which intercepts every request for authentication and it redirects back with headers like SM_USER
