assertion: Unable to locate satisfiable bearer SubjectConfirmation in
This relates directly to SSL offloading via Layer 7 switches or similar.
An example subject confirmation:
<saml:SubjectConfirmationData Address="18.104.22.168" InResponseTo="_1253d4aadec1143fe542a6adfbd06206" NotOnOrAfter="2010-05-25T06:09:49.050Z" Recipient="https://mysqp.example.com.au/Shibboleth.sso/SAML2/Artifact"/>
The recipient the IDP is sending an enityID of 'https://mysqp.example.com.au'. Due to offloading the local shibboleth daemon is generating a comparison string of 'http://mysqp.example.com.au' (note the lack of S). This doesn't match up obviously and the assertion is discarded.
You'll need to change your "ServerName" entry
