Chapter 3. Identity Management

In the previous chapter, we installed OpenStack using RDO. Now that OpenStack is ready for use, we will begin to investigate what was installed and how to use it, starting with identity management. Keystone is the identity management component in OpenStack. In this chapter, we will look at service registration and the relationship of users with tenants and the role of a user in a tenant.
