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If the cached authenticator information is out of date, the validity of the authentication information may be questionable.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 that 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). The CA API Gateway must be configured to use an organization-defined value for determining the expiration of cached data from an identity provider or third party, such as a SAML Token Service.
