Parts IV and V of the Troubleshooting OpenSSO with Firefox Add-Ons were published this afternoon. Take a look at the detailed HTTP traffic that is sent between the browser and OpenSSO during a typical SAML exchange using the Fedlet. Understanding how to use Firefox Add-Ons to decipher the HTTP requests and responses will greatly help in your deployment of OpenSSO as you discover the details of how this technology works.
I want to give Rick Palkovic a big shout out for helping get this published. Thanks Rick!
