    ****************************************************************
    When performing a logout, the OpenID Connect (OIDC) Relying
    Party (RP) Trust Association Interceptor (TAI) provides no
    method to invoke the revocation endpoint on the OpenID
    Connect Provider (OP).
    

Problem conclusion

  • The OIDC TAI is updated to add a configuration option for
    the
    OP's token revocation endpoint.  When logout is performed,
    if
    a revocation endpoint is configured, the revocation endpoint
    will be invoked for the refresh token.
    
    OPs should revoke the access token associated with the
    refresh
    token.  However, they are not required to do so.  An OIDC
    TAI
    configuration option is provided to instruct the TAI to
    perform a separate revocation request for the access token.
    This option defaults to FALSE.
    
    
    The following OIDC TAI properties are added:
    
    provider_<id>.revokeEndpointUrl
    default=(none)
    description=Specifies the endpoint URL for calling the
    OpenID
    Connect Provider's token revocation endpoint.
    
    provider_<id>.revokeAccessToken
    default=false
    description=By default, when a logout is performed, a
    revocation request is only made for the refresh token.  The
    OP should revoke both the refresh token and its
    associated access token with this request. When this
    property
    is set to true, a separate revocation request is made for
    the
    access token.
    
    
    The fix for this APAR is currently targeted for inclusion in
    fix pack 8.5.5.14 and 9.0.0.9.  Please refer to the
