If that's the case than what's in that metadata doesn't match what the
IdP is sending:

> 2013-07-09 15:48:52 WARN OpenSAML.MessageDecoder.SAML2 [2]: no metadata found, can't establish identity of issuer (https://amlib.co.uk/idp:8443/shibboleth)

> 2013-07-09 15:48:52 WARN Shibboleth.SSO.SAML2 [2]: detected a

So what is the IdP's entityID according to the IdP configuration
(relying-party.xml), according to the protocol message (shibd.log on
DEBUG) and according to the SAML metadata on disk at the SP?
