I am trying to authenticate with a PingFederate Idp. I am using asp.net mvc4 which provides wsfed via the Identity and access tool. It appears I am getting the saml assertion back fine. The Idp does require that the certificate is present and confirmed on the SP. I have the certificate from the Idp and installed it in trusted roots. I am using this line in web.config to have it look in trusted roots.
<certificateValidation certificateValidationMode="ChainTrust" / >
This is the exact error I am getting from my asp.net:
Crypto algorithm 'http://www.w3.org/2001/04/xmldsig-more#rsa-sha512' not supported in this context.
If it is finding the correct cert and just can't do sha512, what are my options?
