Question:
Fiware Keyrock how to authenticate from python-keystoneclient

Description:
I am using fiware-idm. I find python-keystone client to to interact with keystone API with easy way .
But I have problem with authentication. creating regular user with default "idm" user it's not problem . but i can not find way how to autenticate this user.

here is my test samples :
create user :

def create_user():
user = keystone.users.create(name="user4",
default_project="idm",
domain="default",
password="qwerty",
email="user4@email.com",
description="this is user description",
enabled=True,
username="user4")
return user

authentication:

auth = v3.Password(auth_url="http://192.168.33.10:5001/v3",
username="user4",
password="qwerty",
domain_name="idm"
)
sess = session.Session(auth=auth)
keystone = client.Client(session=sess)
print keystone.users.list()

It writes that :

keystoneclient.exceptions.Unauthorized: The request you have made requires authentication. (HTTP 401)
