That message means that the IDP thinks this is a proprietary
Shibboleth protocol request for SAML1 (probably because you're
accessing the matching profile handler, i.e., you're sending it to the
wrong URL), but the behaviour you describe (base64 and deflate
encoding) is for SAML 2.0 Authentication Requests.
