{ name={OpenStack Identity},
  description={OpenStack Identity (Keystone) provides a central
    directory of users mapped to the OpenStack services they can
    access. It acts as a common authentication system across the cloud
    operating system and can integrate with existing backend directory
    services. It supports multiple forms of authentication including
    standard username/password credentials and token-based systems.
    In the VSC cloud, it is integrated with the VSC account system.},

  additional management tools. The dashboard is also brand-able for
  service providers and other commercial vendors who want to make use of
  it. The dashboard is one of several ways users can interact with
  OpenStack resources. Developers can automate access or build tools to
  manage resources using the native OpenStack API or the EC2
  compatibility API.},
