Add "Extraction" to the cookie object. Only the cookie object would  
know how to extract credentials coming back from the cookie object's  
challenge. Makes sense, doesn't it?

I have described such a setup before either here or on the PAS list  
itself, take a look at the archives. The very first challenge and  
extraction is done by the cookie auth helper, and the credentials are  
then stored by the session auth helper which is doing all extractions  
after that.
