             Summary: SamlValidator does not work with chain trust
                 Key: CXF-7941
                 URL: https://issues.apache.org/jira/browse/CXF-7941
             Project: CXF
          Issue Type: Bug
          Components: WS-* Components
    Affects Versions: 3.2.7
            Reporter: Tomas Vanhala


As explained here [http://coheigea.blogspot.com/2012/08/subject-dn-certificate-constraint.html,] WSS4J supports specifying constraints on the subject DN of the certificate used for signature validation.

We have successfully applied "direct trust" when receiving SOAP requests containing a signed SAML token.

We attempted to migrate to "chain trust" by removing the certificate used to sign the requests from the Merlin trust store, and setting an appropriate Subject DN Cert Constraint.

It did not work. Our analysis is that WSS4J's SamlValidator is not able to handle a scenario where the certificate used to sign the requests is not in the trust store. The problem seems to be in the method findPublicKeyInKeyStore() of Merlin.java.

We were able to make chain trust (and the Subject DN Cert Constraint) work by including the needed PKI code in a customised SamlValidator, but we would rather not go this route.

Please fix chain trust in WSS4J SAML validation.
