1. Can my authentication process display a login page for the user in their browser?</div>

<div>As long as you can honor the SAML rules of forced authentication and is passive, I think it would be fine. Note well the must here.</div>

2. After I have authenticated the user, where can I find the LoginHandler interface and what does it mean to invoke <code class="">edu.internet2.middleware.shibboleth.idp.authn.AuthenticationEngine#returnToAuthenticationEngine(HttpServletRequest,HttpServletResponse</code>.?</div>

<div class="">I’ve heard that this interface is much easier to implement. I think it’s closer to the basis for IdPv3, as well.</div>

<div class="">But, basically, you just set CGI variables and then invoke the IdP at the right path.</div>
