Managing Projects and Users
ops_projects.rst ops_quotas.rst ops_users.rst ops_projects_users_summary.rst
An OpenStack cloud does not have much value without users. This chapter covers topics that relate to managing users, projects, and quotas. This chapter describes users and projects as described by version 2 of the OpenStack Identity API.
Warning
While version 3 of the Identity API is available, the client tools do not yet implement those calls, and most OpenStack clouds are still implementing Identity API v2.0.
Projects or Tenants?
In OpenStack user interfaces and documentation, a group of users is
referred to as a project or tenant. These terms are interchangeable.
The initial implementation of OpenStack Compute had its own
authentication system and used the term project. When
authentication moved into the OpenStack Identity (keystone) project, it
used the term tenant to refer to a group of users. Because
of this legacy, some of the OpenStack tools refer to projects and some
refer to tenants.
Tip
This guide uses the term project, unless an example
shows interaction with a tool that uses the term
tenant.
