Public bug reported:

Hi, I can't get authentication with os-token and os-url on Juno pythone-
neutronclient.

On Icehouse, with os-token and os-url, we can get authentication.
[root@compute01 ~]# neutron --os-token $token --os-url http://controller:9696 net-list

But on Juno, it failed. The detail :

my solution is this:
On /usr/lib/python2.6/site-packages/neutronclient/shell.py, modify the authenticate_user(self) method.

 Origin:
 auth_session = self._get_keystone_session()

Modified: 
        auth_session = None
        auth = None
        if not self.options.os_token:
            auth_session = self._get_keystone_session()
            auth = auth_session.auth
