I need to know how to modify this form. I cannot find a template or any documentation on the subject. I have read all the SAML documentation and understand quite well how it works, and am just looking for some direction into where I can find the code that generates this file exactly so I can modify it. Any direction here is appreciated.
Thanks for the reply. The problem is that the IDP does not have a session store, so loses SP context during SP initiated authentication and cannot properly redirect the user to the consume URL. The solution is to urlencode the AuthnRequest and other parameters and place them in the query string. The simplest way to do this is to change that form from a POST to a GET. That simple change will solve our problems. Essentially, the IDP does not currently support SP initiated via POST. AEM does not provide an option to configure the request method used in that form. It seems foolish to rewrite the bundle to change 4 characters - I was hoping there was a more deliberate way to approach that change.
