.. warning::
Constructing an instance of this class without a session is
deprecated as of the 1.7.0 release and will be removed in the
2.0.0 release.
The client can be created and used like a user or in a strictly
bootstrap mode. Normal operation expects a username, password, auth_url,
and tenant_name or id to be provided. Other values will be lazily loaded
as needed from the service catalog.
Example::
>>> from keystoneclient.v2_0 import client
>>> keystone = client.Client(username=USER,
... password=PASS,
... tenant_name=TENANT_NAME,
... auth_url=KEYSTONE_URL)
>>> keystone.tenants.list()
...
>>> user = keystone.users.get(USER_ID)
>>> user.delete()
Once authenticated, you can store and attempt to re-use the
authenticated token. the auth_ref property on the client
returns as a dictionary-like-object so that you can export and
cache it, re-using it when initiating another client::
>>> from keystoneclient.v2_0 import client
>>> keystone = client.Client(username=USER,
... password=PASS,
... tenant_name=TENANT_NAME,
... auth_url=KEYSTONE_URL)
>>> auth_ref = keystone.auth_ref
>>> # pickle or whatever you like here
>>> new_client = client.Client(auth_ref=auth_ref)
Alternatively, you can provide the administrative token configured in
keystone and an endpoint to communicate with directly. See
(``admin_token`` in ``keystone.conf``) In this case, authenticate()
is not needed, and no service catalog will be loaded.
Example::
>>> from keystoneclient.v2_0 import client
>>> admin_client = client.Client(
... token='12345secret7890',
... endpoint='http://localhost:35357/v2.0')
>>> admin_client.tenants.list()
