Subscribe

You can track all active APARs for this component.

APAR status

  • Closed as program error.

Error description

  • When the SAML TAI saves and restores the POST parameters from a
    request which was saved during an error page redirect, the POST
    parameters are inaccessible to application code because they're
    restored prior to the request being sent to the application.

Problem summary

  • ****************************************************************
    * USERS AFFECTED:  Administrators of IBM WebSphere Application *
    *                  Server and the SAML Web SSO TAI             *
    ****************************************************************
    * PROBLEM DESCRIPTION: SAML Web SSO TAI may not restore        *
    *                      original "POST" parameters properly     *
    ****************************************************************
    * RECOMMENDATION:  Install a fix pack that contains this       *
    *                  APAR.                                       *
    ****************************************************************
    After the SAML Web SSO Trust Association Interceptor (TAI)
    has processed a SAMLResponse, the original "POST" parameters
    may not be restored properly.
    

Problem conclusion

  • The SAML Web SSO TAI is processing any request that contains a
    SAMLResponse.  However, the SAMLResponse should only be
    processed if the request method is "POST".
    
    The SAML Web SSO TAI is updated to only process a SAMLResponse
    if its request method is "POST".
    
    The fix for this APAR is currently targeted for inclusion in
    fix packs 7.0.0.41, 8.0.0.12 and 8.5.5.9.  Please refer to the
