The error says that you don't have permissions.
It's caused by not specifying interface which the method AddConnection should 
be called on.

so do:
sys_bus = dbus.SystemBus()
proxy = sys_bus.get_object("org.freedesktop.NetworkManagerUserSettings", 
"/org/freedesktop/NetworkManagerSettings")
iface = dbus.Interface(proxy, "org.freedesktop.NetworkManagerSettings")

iface.AddConnection(settings)

Btw, what distribution do you use and what policies do you have in 
/etc/dbus-1/system.d/nm-applet.conf ?
