title: ADFS and PingFederate SSO : SAML Message has wrong signature
body: <p>I am trying to implement SSO for a service and using ADFS and PingFederate as  IDP. </p>
  
  <p>SSO works when I avoid signing the AuthRequest (both with ADFS and PingFederate), but fails with following error "SAML Message has wrong signature. Issuer: 'My SP entityID' " when AuthRequest is signed.</p>
  
  <p>I had updated corresponding Relying trust part with certificate of my SP. I think, i am doing something wrong in the IDP configuration. Any help is appreciated.</p>
