Comment # 8 on bug 972480 from Bj�rn Lie

Based on comment 7 I'll close this one.

If a connection is a "System connection" I.E a connection shared with all
users, admin password is expected to be required.

This is due to upstream and last but not least our current security (polkit)
settings.

Is this unfortunate? - Indeed it is, but I'm not willing to fight the sec team
on this one, as we have tried in the past.

Admins/users may work around this via copying the following into 
/etc/polkit-default-privs.local

org.freedesktop.NetworkManager.enable-disable-network     yes:yes:yes
org.freedesktop.NetworkManager.enable-disable-wifi        yes:yes:yes 
org.freedesktop.NetworkManager.enable-disable-wwan        yes:yes:yes
org.freedesktop.NetworkManager.use-user-connections       yes:yes:yes
org.freedesktop.NetworkManager.settings.modify.own        yes:yes:yes
org.freedesktop.NetworkManager.settings.modify.system     yes:yes:yes


and running set_polkit_default_privs after.

DISCLAMER: The above might be "overkill" and insecure - so users and admins are
advised to check if all are needed + changing the defaults are not recommended
and so on :-)
