Goal:

• Configure the other regions to use the central keystone server in the first region to handle all authentication.
• Configure Horizon to act as the single pane of glass allowing users to select their desired region from the drop down
• Disable Keystone on the other regions and point all services to the central keystone server

Acceptance Criteria:

• Keystone and Horizon are running in the central region
• Keystone and Horizon are disabled in the other regions
• All services in the other regions are pointed and the central region keystone server
• Users are able to login and select a region from the drop down menu.

Open questions:

• Memcache is one of the unknowns here, do we need an additional memcached service to handle token caching
• What is required to enable the region drop down in Horizon.
