    The following message is issued intermittently:

    authentication and attribute layers configured for <GSSUP> with
    <NoProtection EstablishTrustInClient > as Supported in the
    configuration file and the server security policy is configured
    with <Integrity Confidentiality > as Required.
    

Problem conclusion

  • The CSIv2 code was modified to wait for the default SSL
    configuration to become available before creating the transport
    layer association options when an sslRef attribute was not
    specified.
    
    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
    delivery information:
    http://www.ibm.com/support/docview.wss?rs=180&uid=swg27004980
    

Temporary fix

  • Specify an sslRef attribute in the client's transportLayer
    element.
