+Multisite configuration guide
+=============================
+
+Multisite identity service management
+=====================================
+
+Goal
+----
+
+A user should, using a single authentication point be able to manage virtual
+resources spread over multiple OpenStack regions.
+
+Before you read
+---------------
+
+This chapter does not intend to cover all configuration of KeyStone and other
+OpenStack services to work together with KeyStone.
+
+This chapter focuses only on the configuration part should be taken into
+account in multi-site scenario.
+
+Please read the configuration documentation related to identity management
+of OpenStack for all configuration items.
+
+http://docs.openstack.org/liberty/config-reference/content/ch_configuring-openstack-identity.html
+
+How to configure the database cluster for synchronization or asynchrounous
+repliation in multi-site scenario is out of scope of this document. The only
+remainder is that for the synchronization or replication, only Keystone
+database is required. If you are using MySQL, you can configure like this:
+
+In the master:
+
+   .. code-block:: bash
+
+      binlog-do-db=keystone
+
+In the slave:
+
+   .. code-block:: bash
+
+      replicate-do-db=keystone
+
+
+Deployment options
+------------------
+
+For each detail description of each deployment option, please refer to the
+admin-user-guide.
+
+-  Distributed KeyStone service with PKI token
+
+   In KeyStone configuration file, PKI token format should be configured
+
+   .. code-block:: bash
+
+      provider = pki
+
+   or
+
+   .. code-block:: bash
+
+      provider = pkiz
+
+   In the [keystone_authtoken] section of each OpenStack service configuration
+   file in each site, configure the identity_url and auth_uri to the address
+   of KeyStone service
+
+   .. code-block:: bash
+
+      identity_uri = https://keystone.your.com:35357/
+      auth_uri = http://keystone.your.com:5000/v2.0
+
+   It's better to use domain name for the KeyStone service, but not to use IP
+   address directly, especially if you deployed KeyStone service in at least
+   two sites for site level high availability.
+
+-  Distributed KeyStone service with Fernet token
+-  Distributed KeyStone service with Fernet token + Async replication (
+   star-mode).
+
+   In these two deployment options, the token validation is planned to be done
+   in local site.
+
+   In KeyStone configuration file, Fernet token format should be configured
+
+   .. code-block:: bash
+
+      provider = fernet
+
+   In the [keystone_authtoken] section of each OpenStack service configuration
+   file in each site, configure the identity_url and auth_uri to the address
+   of local KeyStone service
+
+   .. code-block:: bash
+
+      identity_uri = https://local-keystone.your.com:35357/
+      auth_uri = http://local-keystone.your.com:5000/v2.0
+
+   and especially, configure the region_name to your local region name, for
+   example, if you are configuring services in RegionOne, and there is local
+   KeyStone service in RegionOne, then
+
+   .. code-block:: bash
+
+      region_name = RegionOne
