             Summary: Signed SAML assertion validation error w/ SupportingTokens only policy
                 Key: CXF-5248
                 URL: https://issues.apache.org/jira/browse/CXF-5248
             Project: CXF
          Issue Type: Bug
          Components: WS-* Components
            Reporter: Alessio Soldano
            Assignee: Colm O hEigeartaigh
             Fix For: 3.0.0, 2.6.10, 2.7.7
         Attachments: CXF-5248.txt

I have an endpoint whose WSDL has the following policy:
{noformat}
<wsp:Policy wsu:Id="MyPolicy">
  <wsp:ExactlyOne>
    <wsp:All>
    <sp:SupportingTokens>
      <wsp:Policy>
        <sp:SamlToken  sp:IncludeToken="http://docs.oasis-open.org/ws-sx/ws-securitypolicy/200702/IncludeToken/AlwaysToRecipient">
          <wsp:Policy>
            <sp:WssSamlV20Token11/>
          </wsp:Policy>
        </sp:SamlToken>
      </wsp:Policy>
    </sp:SupportingTokens>
    </wsp:All>
  </wsp:ExactlyOne>
</wsp:Policy>
{noformat}

I've configured the client so that the provided SAML2 assertion is self signed.

The SamlTokenInterceptor deals with the request on server side; a RequestData instance is built up in 'processToken(Element tokenElement, final SoapMessage message)', but no signature crypto is configured in it. As a consequence the validation later fails in SignatureTrustValidator#validate(..) because no crypto can be retrieved.

I assume the security configuration from the incoming message should be propagate to the RequestData instance constructed in the interceptor.
I'm attaching a patch (against 2.7 branch) that solves my specific failure, but I'm not if other props should be propagated.
