Error “WIF10201: No valid key mapping found” when trying to create claims from SAML

Question

I am trying to validate a SAML response which is coming from Siteminder IDP from a third party. I have installed the certificate provided by them. When I call the Valida

Answer 1

Ok found the solution but could't quite understand the readon behind it (complete noob, will update the answer when I know more).

Followed this approach of converting the SAML2 response to WSFed response, then on that new token I ran my code, now the error is gone.

Note : you still have to override the validate token method (which I had originally done) to avoid the following error :

“ID4154: A Saml2SecurityToken cannot be created from the Saml2Assertion because it contains a SubjectConfirmationData which specifies an InResponseTo value. Enforcement of this value is not supported by default. To customize SubjectConfirmationData processing, extend Saml2SecurityTokenHandler and override ValidateConfirmationData.”

Thanks.
