Error description

  • When a web server, for example IBM HTTP Server, is
    communicating with the WebSphere Application Server using a
    trust association interceptor (TAI), the certificate
    information that was used to connect to Application Server
    is not available to the TAI implementation. As a result, the
    TAI implementor cannot establish a trust when it needs to
    know whether a request is came through a web server or
    directly to WebSphere Application ServerWAS.

Problem summary

  • ****************************************************************
    * USERS AFFECTED:  All users of IBM WebSphere Application      *
    *                  Server Liberty - Web Container              *
    ****************************************************************
    * PROBLEM DESCRIPTION: A Trust Association Interceptor (TAI )  *
    *                      can't obtain the Secure Sockets Layer   *
    *                      (SSL) endpoint information (including   *
    *                      certificate information) that was used  *
    *                      to directly connect to the WebSphere    *
    *                      Application Server.                     *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    When a web server, for example IBM HTTP Server, is communicating
    with the WebSphere Application Server (WSAS) using a TAI, the
    certificate information that was used to connect to WSAS is not
    available to the TAI implementation.
    As a result, the TAI implementer cannot establish a trust when
    it is critical to know whether a request has come through a web
    server or directly to WSAS.
    

Problem conclusion

  • The WebContainer code was modified to provide the certificate
    information for a request using HttpServletRequest attributes.
    
    "com.ibm.websphere.ssl.direct_connection_peer_certificates"
    contains a "X509Certificate[]" object of a direct peer's
    certificate.
    
    "com.ibm.websphere.ssl.direct_connection_cipher_suite" contains
    a String object of a direct cipher suite.
    
    "com.ibm.websphere.webcontainer.is_direct_connection" contains a
    Boolean object which indicates whether a connection is through a
    web server or directly to WebSphere Application Server.
    
    
    The fix for this APAR is currently targeted for inclusion in fix
    pack 17.0.0.2.  Please refer to the Recommended Updates page for
