This DisplayString, up to 80 characters, is described as the name of the authentication server list IKE uses for authentication services, falling back to the VR's default authentication list if left unnamed. An admin points this at a specific AAA authentication list when IKE (particularly XAuth dialup logins) needs different credential-checking rules than the virtual router's general default. For example, an admin running a dedicated RADIUS list just for VPN dialup users would name that list here instead of letting IKE fall back to the VR's general-purpose authentication list.
