APAR status

  • Closed as program error.

Error description

  • The client is receiving an "invalidCertificateChain" error when
    their application attempts to call the
    "java.security.cert.X509Certificate certChain [] =
    (java.security.cert.X509Certificate
    [])req.getAttribute?("javax.net.ssl.peer_certificates");" method
    from within their WebSphere Application Server application.
    This method programmatically retrieves the client cert through
    the $WSCC header parameter from the WebSphere Application
    Server plugin.  It is the responsibility of the plugin to
    retrieve the client cert info from the HTTP Server environment
    variables that are set by the HTTP Server during the initial
    SSL handshake with the client.  In the client's case, the
    client cert is being returned as a NULL value on the
    getAttribute call.
    
    WebSphere Application Server plugin was retrieving the client
    cert data using EBCDIC literal keys from tables that use
    ASCII keys.  This resulted in the data not being retrieved
    correctly by the plugin.
    

Local fix

  • Use the WAS v6.1 plugin or access the application directly
    through the WCS_defaulthost_secure transport.
    

Problem summary

  • ****************************************************************
    * USERS AFFECTED:  All users of IBM WebSphere Application      *
    *                  Server version 6.1, 7.0 and 8.0 running on  *
    *                  i5/OS.                                      *
    ****************************************************************
    * PROBLEM DESCRIPTION: An error is observed when an            *
    *                      application ties to retrieve            *
    *                      certain attributes of the client's      *
    *                      certificate.                            *
    ****************************************************************
    * RECOMMENDATION:  Apply the 6.1.0.41, 7.0.0.19 or 8.0.0.1     *
    *                  fix pack.                                   *
    ****************************************************************
    When an application tries to retrieve certain attributes of the
    Client's certificate, eg : "javax.net.ssl.peer_certificates",
    it gets a NULL value instead of a valid certificate or
    certificates.
    

Problem conclusion

  • The plugin has been modified to retrieve SSL values related to
    Client Certificates properly.
    
    The fix for this APAR is currently targeted for inclusion in
    6.1.0.41, 7.0.0.19 and 8.0.0.1 fix packs.  Please refer
