    *                  SAML Web Single Sign-on (SSO)               *

    * PROBLEM DESCRIPTION: SAML Web SSO may prevent other          *
    *                      applications from accessing the HTTP    *

    ****************************************************************
    The SAML Web Single Sign-on (SSO) TAI may prevent applications
    that are running on a different thread from reading the HTTP
    Request Parameter.  This can cause applications that need
    access to the HTTP Request Parameter to fail.
    

Problem conclusion

  • The SAML Web SSO TAI always reads the HTTP Request Parameter
    for a request even if the request is not protected by the TAI.
    This prevents any application running on a different
    thread from accessing the HTTP Request Parameter.
    
    The SAML TAI is updated so that it only reads the HTTP Request
    Parameter if the request is protected by the TAI.
    
    The fix for this APAR is currently targeted for inclusion in
    fix packs 7.0.0.37, 8.0.0.10, and 8.5.5.4.  Please refer to
