SAML 2.0

I have been working a lot with SAML recently, which is a protocol for standardizing single sign on (SSO) between sites. A good number of sites and products use SAML as a SSO protocol, including Google Apps and Moodle, important sites to communicate with in my particular case.

I'm working in .NET 3.5, which unfortunately has no built-in support for SAML 2.0, but there are many third-party libraries and references to build your own support for it.

Here are some of the best links I have found for learning SAML.
