> While recently configuring most of our services to use a discovery service (versus a WAYF) we noticed a got a couple of errors with IdPs encrypting SAML2 assertions using the wrong certificate. This may happen when both the IdP and SP are trusting both our test and production federation.
> It has been very hard for us to determine the origin of the problem and to fix it mostly because the SP logs didn't help much.
> Here is what it looked like :
> 2012-05-10 15:08:40 DEBUG XMLTooling.CredentialCriteria [29470]: credential name(s) didn't overlap
> 2012-05-10 15:08:40 ERROR Shibboleth.SSO.SAML2 [29470]: Unable to resolve any key decryption keys.
> It's misleading because we had no credential name issue.
> It would greatly help if you could add an additional error log entry that tells the SP could not decrypt the assertion.
> Thanks
