Error description

  • If the SubjectConfirmationData NotOnOrAfter or AuthnStatement
    SessionNotOnOrAfter settings are earlier than the Conditions
    NotOnOrAfer setting in a SAML 2.0 token received from an STS,
    the WS-Security SAML token generator may emit the token in a
    web services request which may cause the provider to reject the
    request.

Problem summary

  • ****************************************************************
    * USERS AFFECTED:  IBM WebSphere Application Server users of   *
    *                  WS-Security and SAML 2.0                    *
    ****************************************************************
    * PROBLEM DESCRIPTION: SAML token generator may emit a SAML    *
    *                      2.0 token that is expired.              *
    ****************************************************************
    * RECOMMENDATION:  Install a fix pack that contains this       *
    *                  APAR.                                       *
    ****************************************************************
    The WS-Security SAML token generator may emit SAML 2.0 tokens
    that have already expired.  This can occur when the
    SubjectConfirmationData NotOnOrAfter or AuthnStatement
    SessionNotOnOrAfter settings are earlier than the Conditions
    NotOnOrAfer setting.
    This problem will NOT occur if any of the following conditions
    are met:
    * SAML 1.1 tokens are used
    * Self-issued tokens are used
    * SAML token caching is turned off
    * All NotOnOrAfter settings in the token are the same
    

Problem conclusion

  • When the SAML token generator receives a SAML token from a
    Security Token Service (STS), it caches the token for future
    requests.  A new token is requested from the STS when the
    token expires.
    
    The time that the token expires is based exclusively on the
    NotOnOrAfter attribute in the Conditions element.  If there is
    a NotOrAfter attribute on the SubjectConfirmation element or a
    SessionNotOrAfter attribute on the AuthnStatement element that
    expires before the NotOrAfter on the Conditions element, the
    SAML token will remain in the cache after it has expired and
    may be sent out by the SAML token generator.
    
    The WS-Security runtime is updated to set the token expires
    time to the least of the Conditions NotOrAfter,
    SubjectConfirmationData NotOnOrAfter, and AuthnStatement
    SessionNotOnOrAfter settings.
    
    The fix for this APAR is currently targeted for inclusion in
    fix pack 7.0.0.33, 8.0.0.9, and 8.5.5.3.  Please refer to the
