Error description

  • When the SAML Web SSO TAI ACSTrustAssociationInterceptor uses
    the Cell Level default trust store for signer certificates,
    after the server is started, any signer certificate added to
    the trust store are not picked up immediately.  If a valid SAML
    response is sent that was signed by the certificate that was
    just added, the request is rejected. When the server is
    restarted, the request will be successful.

Problem summary

  • ****************************************************************
    * USERS AFFECTED:  IBM WebSphere Application Server            *
    *                  administrators of WS-Security enabled       *
    *                  JAX-WS applications and SAML Web SSO TAI    *
    ****************************************************************
    * PROBLEM DESCRIPTION: WS-Security and SAML Web SSO do not     *
    *                      recognize updates to centralized        *
    *                      keystores                               *
    ****************************************************************
    * RECOMMENDATION:  Install a fix pack that contains this       *
    *                  APAR.                                       *
    ****************************************************************
    When an application is configured to use a centralized
    keystore for its trust store, when certificates are added or
    deleted from the keystore, the updates are not recognized by
    the application.
    For instance, a WS-Security enabled JAX-WS application is
    configured with a centralized keystore in its X.509 callback
    handler for digital signature.  If a certificate is added to
    the keystore, a message that is signed with that certificate
    will be rejected because it is not trusted.
    Another example: The ACSTrustAssociationInterceptor is
    configured with a centralized keystore for its trust store.
    If a certificate is deleted from the keystore, a message that
    is signed with that certificate will not be rejected, but it
    should be.
    When the application server is restarted, updates to the
    centralized keystore are recognized by the applications and
    the trust evaluation behaves as expected.
    This APAR does not apply to hardcoded keystores.  Updates to
    hardcoded keystores are not intended to be recognized until
    the application server is restarted.
    

Problem conclusion

  • When a centralized keystore is opened by the runtime, an
    instance of the object is cached.  When the keystore is
    modified, the WebSphere runtime creates a new object instead
    of updating the original object, so the object that was cached
    has become obsolete.
    
    The runtime is updated to not cache the keystore objects for
    centralized keystores.
    
    The fix for this APAR is currently targeted for inclusion in
    fix packs 7.0.0.27, 8.0.0.5, and 8.5.0.2.  Please refer to the
