Based on the error msg from the decoder, the problem is that there is
literally no HTTP form parameter named either 'SAMLRequest' or
'SAMLResponse'.

The code that performs this check is pretty simple:

String encodedMessage = transport.getParameterValue("SAMLRequest");
if (DatatypeHelper.isEmpty(encodedMessage)) {
    encodedMessage = transport.getParameterValue("SAMLResponse");
}

if (DatatypeHelper.isEmpty(encodedMessage)) {
    log.error("Request did not contain either a SAMLRequest or "
            + "SAMLResponse paramter.  Invalid request for SAML 2 HTTP
               POST binding.");
    throw new MessageDecodingException("No SAML message present in
                     request");
}





So it sounds like something about the form as produced by the encoder
and posted to the decoder endpoint is screwed up.  What does the encoded
form look like?

This encoder/decoder code is known to work correctly, so something must
be off in the variable inputs that you are supplying on one side or the
other.
