> WSS4J enforces the SubjectConfirmation requirements of an inbound SAML Token. For sender-vouches, a signature must be present that covers both the SOAP Body and the SAML Assertion. As explained here [http://coheigea.blogspot.com/2014/01/apache-wss4j-200-part-ii.html,] the configuration tag defined as ConfigurationConstants.VALIDATE_SAML_SUBJECT_CONFIRMATION ("validateSamlSubjectConfirmation") allows the user to switch off this validation if required.
> We need to switch off the validation, in order to process non-TLS requests where only the SAML assertion is signed.
> Unfortunately, it turns out that SubjectConfirmation validation cannot be switched off when using PolicyBasedWSS4JInInterceptor. It uses SamlTokenPolicyValidator, containing the following code:
>  
> {code:java}
> if (!DOMSAMLUtil.checkSenderVouches(assertionWrapper, tlsCerts, parameters.getSoapBody(), parameters.getSignedResults())) {
>     ai.setNotAsserted("Assertion fails sender-vouches requirements");
>     continue;
> }
> {code}
> This is different from WSS4JInInterceptor, which through WSSecurityEngine uses the following code:
> {code:java}
> if (requestData.isValidateSamlSubjectConfirmation()) {
>     Element bodyElement = callbackLookupToUse.getSOAPBody();
>     DOMSAMLUtil.validateSAMLResults(handlerResult, requestData.getTlsCerts(), bodyElement);
> }
> {code}
> Please add similar handling of the VALIDATE_SAML_SUBJECT_CONFIRMATION configuration tag into PolicyBasedWSS4JInInterceptor.
