    Technically, in that binding the "SimpleSign" signature is not
    mandatory, nor is an XML signature disallowed.  In other words, it
    could look identical to a standard POST binding. So that's not
    significant.  However...<br>

    But more importantly: Looks like they're actually doing
    HTTP-Redirect, based on the use of query params.  So probably this
    is just messed up metadata or configuration somewhere.  <br>

    <br>
    Yes, absolutely.  You'll see the flow itself defined in
    system/conf/webflow-config.xml, and the supporting flow files as
    system/flows/saml/saml2/sso-post-simplesign-{beans,flow}.xml
    (although most of the real guts of the flow are defined in other
    files from which those inherit).  <br>
    <br>
    But POST SimpleSign only supports HTTP POST method and they're doing
    a GET, so that's probably why it's erroring out.  It's just a
    mismatch of binding and recipient endpoint.<br>
