1. APIs marked with the `@Beta` annotation at the class or method level
are subject to change. They can be modified in any way, or even
removed, at any time. If your code is a library itself (i.e. it is
used on the CLASSPATH of users outside your own control), you should
not use beta APIs, unless you [repackage] them. **If your
code is a library, we strongly recommend using the [Guava Beta Checker] to
ensure that you do not use any `@Beta` APIs!**

	m := reqMap["input"].(map[string]interface{})
	accountValue := m["account"].(string)
	actionValue := m["action"].(string)

	// Allow user `minio` to perform any action.
	var res Result
	if accountValue == "minio" {
		res.Result = true
	} else {
		// All other users may not perform any `s3:Put*` operations.
		res.Result = true
		if strings.HasPrefix(actionValue, "s3:Put") {
			res.Result = false
		}
	}

Теперь попробуйте пройти аутентификацию с неактивным пользователем:

Пользователь: `alice`

Пароль: `secret2`

И попробуйте использовать операцию `GET` с путем `/users/me`.

Вы получите ошибку "Inactive user", как тут:

```JSON
{
  "detail": "Inactive user"
}
```

## Резюме

Теперь у вас есть инструменты для реализации полноценной системы безопасности на основе `имени пользователя` и `пароля` для вашего API.

- Contains well-written, logical commits explaining *why* changes were made (e.g., “Add S3 bucket tagging support so that users can organize resources efficiently”).
- Is small, focused, and easy to review—ideally one commit, unless multiple commits better narrate complex work.
- Adheres to MinIO’s coding standards (e.g., Go style, error handling, testing).

        // Test with different names
        LdapUser user2 = new LdapUser(testEnv, "anotheruser");
        assertEquals("anotheruser", user2.getName());

        // Test with empty name
        LdapUser user3 = new LdapUser(testEnv, "");
        assertEquals("", user3.getName());

        // Test with null name
        LdapUser user4 = new LdapUser(testEnv, null);
        assertNull(user4.getName());
    }

  // Technically should accept RemovalNotification<? extends K, ? extends V>, but because
  // RemovalNotification is guaranteed covariant, let's make users' lives simpler.
  void onRemoval(RemovalNotification<K, V> notification);

On the other side, there are thousands of users in the chat systems, so there's a high chance you'll find someone to talk to there, almost all the time. 😄
