Hi, We've got CAS 6.6.x running beautifully with delegated IDP logins to multiple SAML providers, but the most recent one we've had to integrate with is causing me some headaches. The initial redirect works fine, but when it comes back CAS displays the SAML message but then fails to decrypt the SAML message and I can't figure out why - has anyone come across anything similar before?
