Keystone is an OpenStack service that provides API client authentication, service discovery, and distributed multi-tenant authorization by implementing OpenStack’s Identity API.
This documentation is primarily targeted towards contributors of the project, and assumes that you are already familiar with Keystone from an end-user perspective; however, end users, deployers, and operators will also find it useful.
This documentation is generated by the Sphinx toolkit and lives in the source tree. Also see the Getting Involved page for other ways to interact with the community.
