APAR status

  • Closed as program error.

Error description

  • When following configurations are set together, two part http
    response is returned. The first part is NTLM (NT LAN
    Manager) token error and the second part is application page.

    * PROBLEM DESCRIPTION: Two part http response is returned.     *
    *                      The first part is NTLM (NT LAN          *
    *                      Manager) token error. The second part   *
    *                      is application page.                    *

    * RECOMMENDATION:                                              *
    ****************************************************************
    When NTLM Token is in the HTTP request, SPNEGO Web
    authentication detects it and adds "NTLM Token received" error
    message to the HTTP Response.  Then, the Application
    server falls back on application authentication mechanism when
    "Allow fallback to application authentication mechanism" is
    enabled. If the authentication is successful, application page
    is added to HTTP response. This results in two part HTTP
    response, the first part with "NTLM Token received" error and
    the second part with application page.
    

Problem conclusion

  • With this fix, when SPNEGO Web authentication is used, the
    security code no longer appends the error message if "Allow
    fallback to application authentication mechanism" is enabled,
    
    The fix for this APAR is currently targeted for inclusion in
    fix pack 7.0.0.21 and 8.0.0.2.  Please refer to the Recommended
