Role-Based Access Control Commands
With Role-Based Access Control (RBAC), access and authorization is controlled based on a user’s role.
Users are granted permissions based on their user roles, not on their individual user ID. User roles are
created for job functions and through those roles they acquire the permissions to perform their
associated job function.
This section describes the syntax and usage of RBAC-specific commands. You can find information on
other related security commands in this chapter:
