Add an identity user guide to replace the current placeholder. Also, add identity examples and related tests to go along with the guide. Much of the content for the guide was pulled from [1].

Using OpenStack Identity
|
|
========================
|
|
|
|
Before working with the Identity service, you'll need to create a connection
|
|
to your OpenStack cloud by following the :doc:`connect` user guide. This will
|
|
provide you with the ``conn`` variable used in the examples below.
|
|
|
|
The OpenStack Identity service is the default identity management system for
|
|
OpenStack. The Identity service authentication process confirms the identity
|
|
of a user and an incoming request by validating a set of credentials that the
|
|
user supplies. Initially, these credentials are a user name and password or a
|
|
user name and API key. When the Identity service validates user credentials,
|
|
it issues an authentication token that the user provides in subsequent
|
|
requests. An authentication token is an alpha-numeric text string that enables
|
|
access to OpenStack APIs and resources. A token may be revoked at any time and
|
|
is valid for a finite duration.
|
|
|
|
List Users
|
|
----------
|
|
A **user** is a digital representation of a person, system, or service that
|
|
uses OpenStack cloud services. The Identity service validates that incoming
|
|
requests are made by the user who claims to be making the call. Users have
|
|
a login and can access resources by using assigned tokens. Users can be
|
|
directly assigned to a particular project and behave as if they are contained
|
|
in that project.

|
|
|
|
List Credentials
|
|
----------------
|
|
**Credentials** are data that confirms the identity of the user. For example,
|
|
user name and password, user name and API key, or an authentication token that
|
|
the Identity service provides.

|
|
|
|
List Projects
|
|
-------------
|
|
A **project** is a container that groups or isolates resources or identity
|
|
objects.
|
|
|
|
.. literalinclude:: ../examples/identity/list.py
|
|
:pyobject: list_projects
|
|
|
|

|
|
|
|
List Domains
|
|
------------
|
|
A **domain** is an Identity service API v3 entity and represents a collection
|
|
of projects and users that defines administrative boundaries for the management
|
|
of Identity entities. Users can be granted the administrator role for a domain.
|
|
A domain administrator can create projects, users, and groups in a domain and
|
|
assign roles to users and groups in a domain.
|
|
|
|
.. literalinclude:: ../examples/identity/list.py
|
|
:pyobject: list_domains
|
|
|
|
Full example: `identity resource list`_
|
|
|
|
List Groups
|
|
-----------
|
|
A **group** is an Identity service API v3 entity and represents a collection of
|
|
users that are owned by a domain. A group role granted to a domain or project
|
|
applies to all users in the group. Adding users to, or removing users from, a
|
|
group respectively grants, or revokes, their role and authentication to the
|
|
associated domain or project.

|
|
|
List Services
|
|
-------------
|
|
A **service** is an OpenStack service, such as Compute, Object Storage, or
|
|
Image service, that provides one or more endpoints through which users can
|
|
access resources and perform operations.
|
|
|

|
List Endpoints
|
|
--------------
|
|
An **endpoint** is a network-accessible address, usually a URL, through which
|
|
you can access a service.

|
|
|
List Regions
|
|
------------
|
|
A **region** is an Identity service API v3 entity and represents a general
|
|
division in an OpenStack deployment. You can associate zero or more
|
|
sub-regions with a region to make a tree-like structured hierarchy.
|
