Login.jsp does nothing.

It is simply an html form that collects a login ID and password that get submitted to the authentication servlet. The servlet is where all the magic happens.

As Scott has mentioned, you are essentially looking into the private parts. Shib documents Login Handlers. The UsernamePassword login handler is one of them and includes a page called login.jsp that it uses in its own private and proprietary way to collect the information it deems important and necessary in order to authenticate a user.

Now, you can certainly much with that as much as you want, you have all the code. But to do it right and do anything beyond a trivial implementation, you will have to build a full Login Handler:
