Hello,

I am getting basic authorization error from cinder client on volume listing. The keystone service-list and endpoint-list are checked. Those are fine.

>>> from cinderclient import client
>>> cinder = client.Client('2', 'admin', pw, 'demo', 'http://10.72.xx.yyyy:8776/v2')
>>> cinder.volumes.list()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/opt/stack/python-cinderclient/cinderclient/v2/volumes.py", line 291, in list
    "volumes", limit=limit)
  File "/opt/stack/python-cinderclient/cinderclient/base.py", line 65, in _list
    resp, body = self.api.client.get(url)
  File "/opt/stack/python-cinderclient/cinderclient/client.py", line 288, in get
    return self._cs_request(url, 'GET', **kwargs)
  File "/opt/stack/python-cinderclient/cinderclient/client.py", line 245, in _cs_request
    self.authenticate()
  File "/opt/stack/python-cinderclient/cinderclient/client.py", line 400, in authenticate
    auth_url = self._v1_auth(auth_url)
  File "/opt/stack/python-cinderclient/cinderclient/client.py", line 423, in _v1_auth
    resp, body = self.request(url, 'GET', headers=headers)
  File "/opt/stack/python-cinderclient/cinderclient/client.py", line 234, in request
    raise exceptions.from_response(resp, body)
cinderclient.exceptions.Unauthorized: Unauthorized (HTTP 401)

However 'cinder list' or the horizon works fine.

Any such clue will be helpful.
