I have a “real” authentication service , but rather than go for the highest level of complexity at first, I’d just like to have my external auth service do something like look up the Userid in a flat file, and return an Authenticated/Not Authenticated indication based on that lookup.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>My problem is that I know how long it took me to understand the basic Shibboleth 2 setup and configuration, and based on that experience I think it will take me FOREVER to extend the authentication functionality. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Can someone point me to a <i>simple</i> example of this kind of customization, or, could someone suggest an article, blog, or web page that would help me understand the overall mechanics of this problem?
