Steve Martinelli 0b2753f924 Rename admin-guide files: keystone -> identity
Most of the files in the admin guide do not use the project's
code name, with keystone being an exception. Let's rename
them to identity.

=============================
Domain-specific configuration
=============================
The Identity service supports domain-specific Identity drivers.
The drivers allow a domain to have its own LDAP or SQL back end.
By default, domain-specific drivers are disabled.
Domain-specific Identity configuration options can be stored in
domain-specific configuration files, or in the Identity SQL
database using API REST calls.
.. note::
Storing and managing configuration options in an SQL database is
experimental in Kilo, and added to the Identity service in the
Liberty release.
Enable drivers for domain-specific configuration files
------------------------------------------------------
To enable domain-specific drivers, set these options in the
``/etc/keystone/keystone.conf`` file:
.. code-block:: ini
[identity]
domain_specific_drivers_enabled = True
domain_config_dir = /etc/keystone/domains
When you enable domain-specific drivers, Identity looks in the
``domain_config_dir`` directory for configuration files that are named as
``keystone.DOMAIN_NAME.conf``. A domain without a domain-specific
configuration file uses options in the primary configuration file.
Enable drivers for storing configuration options in SQL database
----------------------------------------------------------------
To enable domain-specific drivers, set these options in the
``/etc/keystone/keystone.conf`` file:
.. code-block:: ini
[identity]
domain_specific_drivers_enabled = True
domain_configurations_from_database = True
Any domain-specific configuration options specified through the
Identity v3 API will override domain-specific configuration files in the
``/etc/keystone/domains`` directory.
Migrate domain-specific configuration files to the SQL database
---------------------------------------------------------------
You can use the ``keystone-manage`` command to migrate configuration
options in domain-specific configuration files to the SQL database:
.. code-block:: console
# keystone-manage domain_config_upload --all
To upload options from a specific domain-configuration file, specify the
domain name:
.. code-block:: console
# keystone-manage domain_config_upload --domain-name DOMAIN_NAME
