Ok, you dont want to use OpenAM for this. For this I suggest using the OpenSAML library which is build for more manual low-level processing of SAML messages. More information about OpenSAML https://wiki.shibboleth.net/confluence/display/OpenSAML/Home I also have a blog where I have written a few guides and tips https://blog.samlsecurity.com/categories/opensaml/
