RBAC Overview

Overview​

Role-Based Access Control (RBAC) assigns permissions to users according to their roles. Casbin implements RBAC with support for role hierarchies, domains, and conditions.

RBAC in Casbin​

  • Basic RBAC — Role hierarchies and user–role assignments
  • RBAC with pattern — Pattern matching for flexible role assignment
  • RBAC with domains — Multi-tenancy with per-domain roles
  • RBAC with conditions — Conditional logic in role-based permissions
  • RBAC96 — Alignment with the NIST RBAC96 model

Getting started​

  1. Define the role hierarchy and request/policy shape in the model.
  2. Assign users to roles (and optionally resources to roles) in policy.
  3. Use the RBAC API to manage roles and check permissions.

See the sections below for each variant and implementation details.
