Problem summary

  • ****************************************************************
    * USERS AFFECTED:  All users of IBM WebSphere Application      *
    *                  Server and OIDC                             *
    ****************************************************************
    * PROBLEM DESCRIPTION: The OIDC RP may attempt to refresh an   *
    *                      access token even if there is no        *
    *                      refresh                                 *
    *                      token associated with it.               *
    ****************************************************************
    * RECOMMENDATION:  Install a fix pack or interim fix that      *
    *                  contains this APAR.                         *
    ****************************************************************
    When an access token expires, if refresh is enabled and there is
    a
    refresh token associated with the access token, the OpenID
    Connect
    (OIDC) Relying Party (RP) will attempt to refresh the access
    token
    using the refresh token.
    When there is no refresh token associated with the access token,
    the RP may still attempt to refresh the access token.
    

Problem conclusion

  • The OIDC RP TAI is update so that it will only attempt to refres
    access tokens when refresh is enabled a refresh token exists for
    the access token.
    
    The fix for this APAR is targeted for inclusion in fix packs
    8.5.5.18 and 9.0.5.4.  For more information, see 'Recommended
