Authenticating using Identity Server API v3
-------------------------------------------
To authenticate against an Identity Server API v3, the
``OS_IDENTITY_API_VERSION`` environment variable or
``--os-identity-api-version`` option must be changed to ``3``, instead of the
default ``2.0``. Similarly ``OS_AUTH_URL`` or ``os-auth-url`` should also be
updated.
.. code-block:: bash
$ export OS_IDENTITY_API_VERSION=3 (Defaults to 2.0)
$ export OS_AUTH_URL=http://localhost:5000/v3
Since Identity API v3 authentication is a bit more complex, there are additional
options that may be set, either as command line options or environment
variables. The most common case will be a user supplying both user name and
password, along with the project name; previously in v2.0 this would be
sufficient, but since the Identity API v3 has a ``Domain`` component, we need
to tell the client in which domain the user and project exists.
If using a user name and password to authenticate, specify either it's owning
domain name or ID.
* ``--os-user-domain-name`` or ``OS_USER_DOMAIN_NAME``
* ``--os-user-domain-id`` or ``OS_USER_DOMAIN_ID``
If using a project name as authorization scope, specify either it's owning
domain name or ID.
* ``--os-project-domain-name`` or ``OS_PROJECT_DOMAIN_NAME``
* ``--os-project-domain-id`` or ``OS_PROJECT_DOMAIN_ID``
If using a domain as authorization scope, set either it's name or ID.
* ``--os-domain-name`` or ``OS_DOMAIN_NAME``
* ``--os-domain-id`` or ``OS_DOMAIN_ID``
Note that if the user and project share the same domain, then simply setting
``os-default-domain`` or ``OS_DEFAULT_DOMAIN`` is sufficient.
Thus, a minimal set of of environment variables would be:
.. code-block:: bash
$ export OS_IDENTITY_API_VERSION=3
$ export OS_AUTH_URL=http://localhost:5000/v3
$ export OS_DEFAULT_DOMAIN=default
$ export OS_USERNAME=admin
$ export OS_PASSWORD=secret
$ export OS_PROJECT_NAME=admin
