Descriptions

When using an authentication mechanism other than PKI, when the user clicks Log Out in NiFi versions 1.0.0 to 1.9.2, NiFi invalidates the authentication token on the client side but not on the server side. This permits the user's client-side token to be used for up to 12 hours after logging out to make API requests to NiFi.

Cuando se utiliza un mecanismo de autenticación diferente de PKI, al momento que el usuario hace clic en el Log Out en NiFi versiones 1.0.0 hasta 1.9.2, NiFi invalida el token de autenticación en el lado del cliente pero no en el lado del servidor. Esto permite que el token del lado del cliente del usuario sea usado hasta 12 horas después de cerrar sesión para llevar a cabo peticiones de la API a NiFi.
