Description
If the cached authenticator information is out of date, the validity of the authentication information may be questionable. This requirement applies to all ALGs which may cache user authenticators for use throughout a session. This requirement also applies to ALGs that provide user authentication intermediary services (e.g., authentication gateway or TLS gateway). This does not apply to authentication for the purpose of configuring the device itself (device management).
