Administrative credentials when adding a WEP/WPA/WPA2 Enterprise wifi profile?

Hello,

Why do users need to provide administrative credentials when they install a configuration profile containing installation of a WEP Enterprise or WPA/WPA2 Enterprise Wifi-profile? This is not the case when installing a Wifi-profile usning standad WEP, WPA or WPA2.

Is this a bug? It confuses users with user profiles when they need to confirm the installation with administrative credentials.
