Model kontrol akses hibrida

Casbin abstracts access control models into CONF files based on the PERM metamodel (Policy, Effect, Request, Matchers). Switching or upgrading your project's authorization mechanism is as simple as modifying a configuration file.

Permanensi Kebijakan

Casbin implements policy storage through adapters (middleware components). To maintain a lightweight core, adapter code is not included in the main library (except for the default file adapter). We welcome third-party adapter contributions. For a complete list of available adapters and detailed documentation, please refer to: adaptor.

Policy Enforcement at Scale

Some adapters support filtered policy management, meaning Casbin loads only a subset of policies from storage based on specified filters. This enables efficient policy enforcement in large, multi-tenant environments where loading the entire policy set would create a performance bottleneck.

Role Manager

The role manager handles RBAC role hierarchies (user-role mappings) in Casbin. It can retrieve role data from Casbin policy rules or external sources such as LDAP, Okta, Auth0, Azure AD, and others. We support multiple role manager implementations. To maintain a lightweight core, role manager code is not included in the main library (except for the default implementation).
