Comment # 3 on bug 1204114 from Michal Suchanek

Relevant policy kit rule seems to be:

                'org.freedesktop.NetworkManager.settings.modify.own':
                        [ 'auth_admin_keep', 'auth_admin_keep', 'yes' ],
                'org.freedesktop.NetworkManager.settings.modify.system':
                        [ 'auth_admin_keep', 'auth_admin_keep',
'auth_admin_keep' ],
