After the Auth Manager computes the default result (allowed or denied based on the user's permissions), if this callback is set, it is invoked with the preliminary result. The callback may change the result (e.g., grant access that would otherwise be denied, or deny access that would otherwise be allowed). + +The callback is invoked from `wh_Auth_CheckRequestAuthorization` in `src/wh_auth.c`. Parameters: context, preliminary err, user_id, group, action. Returns the final authorization result. + +### CheckKeyAuthorization + +Placeholder for checking whether a user is authorized to use a specific key ID. This callback is defined in the interface but wolfHSM currently does not invoke it before key use; it is a TODO for future integration. When implemented, it would allow the backend to override key-access decisions (e.g., based on the user's `keyIds` array in permissions). + +## Error Codes + +Auth-related error codes in `wolfhsm/wh_error.h`: + +| Code | Value | Description | +|------|-------|-------------| +| `WH_AUTH_LOGIN_FAILED` | -2300 | User login attempt failed | +| `WH_AUTH_PERMISSION_ERROR` | -2301 | User attempted an action not allowed | +| `WH_AUTH_NOT_ENABLED` | -2302 | Server does not have auth feature | + +## Thread Safety and Locking + +### Conditional compilation + +When `WOLFHSM_CFG_THREADSAFE` is defined, the Auth Manager uses a lock (`whLock`) stored in `whAuthContext` to serialize auth operations. When undefined, locking is disabled and `WH_AUTH_LOCK`/`WH_AUTH_UNLOCK` expand to no-ops (return `WH_ERROR_OK`). + +### Lock acquisition + +All public Auth Manager API functions in `src/wh_auth.c` acquire the lock via `WH_AUTH_LOCK` at entry and release via `WH_AUTH_UNLOCK` before return. Callbacks (Login, Logout, UserAdd, etc.) are invoked while holding the lock. + +### Base implementation + +The default user database in `wh_auth_base.c` uses a static global users array. When `WOLFHSM_CFG_THREADSAFE` is defined, this array is protected by the auth context lock; locking is performed by the `wh_Auth_*` wrapper functions, not by the base implementation itself. + +### Configuration + +`whAuthConfig` includes an optional `lockConfig` (of type `whLockConfig`) when `WOLFHSM_CFG_THREADSAFE` is defined; this is passed to `wh_Lock_Init` during `wh_Auth_Init`. Custom backends that maintain shared state must either rely on this lock or implement their own synchronization.
