Problem Definition
With the introduction of 802.1X, IKEv2 EAP mode, and RADIUS-based SIP, a single “subscription” at a AAA server can technically be used for multiple “services”
Providers may apply policies as to what services can actually be used in practice
One reason for this is commercial
E.g., you did not pay for more than one service
Another reason is the different properties
E.g., security level in VPN vs .WLAN
