Actually it is not authenticating it self against keystone, it is
communicating directly to nova by using a ketstone client

in neutron.conf you have to options which are set to True by default, they
are

notify_nova_on_port_status_changes

notify_nova_on_port_data_changes

If you set both of them to False, you wont have any errors any more, but if
for some reason you require using neutron nova notification, then you must
configure nova authentication and api url in neutron.conf

You will find in neutron.conf a section named nova, under it you will see
all condiguration option you can use to configure the notification driver
to notify nova on status or data changes on ports
