Chapter 1. Preface

Identity service

As a cloud administrator, you can manage projects, users, and roles.

Projects are organizational units containing a collection of resources. You can assign users to roles within projects. Roles define the actions that those users can perform on the resources within a given project. Users can be assigned roles in multiple projects.

Each Red Hat OpenStack (RHOSP) deployment must include at least one user assigned to a role within a project. As a cloud administrator, you can:

  • Add, update, and delete projects and users.
  • Assign users to one or more roles, and change or remove these assignments.
  • Manage projects and users independently from each other.

You can also configure user authentication with the Identity service (keystone)to control access to services and endpoints. The Identity service provides token-based authentication and can integrate with LDAP and Active Directory, so you can manage users and identities externally and synchronize the user data with the Identity service.
