잠금 아이콘을 클릭하고 로그아웃한 다음 동일한 작업을 다시 시도하면 다음과 같은 HTTP 401 오류가 발생합니다.

```JSON
{
  "detail": "Not authenticated"
}
```

### 비활성된 유저

이제 비활성된 사용자로 시도하고, 인증해봅시다:

유저명: `alice`

패스워드: `secret2`

그리고 `/users/me` 경로와 함께 `GET` 작업을 사용해 봅시다.

다음과 같은 "Inactive user" 오류가 발생합니다:

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

## 요약

```JSON
{
  "detail": "Not authenticated"
}
```

### Inaktiver Benutzer

Versuchen Sie es nun mit einem inaktiven Benutzer und authentisieren Sie sich mit:

Benutzer: `alice`.

Passwort: `secret2`.

Und versuchen Sie, die Operation `GET` mit dem Pfad `/users/me` zu verwenden.

Sie erhalten die Fehlermeldung „Inactive user“:

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

```JSON
{
  "detail": "Not authenticated"
}
```

### Inactive user

Now try with an inactive user, authenticate with:

User: `alice`

Password: `secret2`

And try to use the operation `GET` with the path `/users/me`.

You will get an "Inactive user" error, like:

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