Answer

  • You can't have OpenStack deployed without Keystone
    • It Provides identity, policy and token services
      • The authentication provided is for both users and services
      • The authorization supported is token-based and user-based.
    • There is a policy defined based on RBAC stored in a JSON file and each line in that file defines the level of access to apply
