UserInDB(**user_dict)
```

sería equivalente a algo como:

```Python
UserInDB(
    username="john",
    password="secret",
    email="******@****.***",
    full_name=None,
)
```

O más exactamente, usando `user_dict` directamente, con cualquier contenido que pueda tener en el futuro:

```Python
UserInDB(
    username = user_dict["username"],
    password = user_dict["password"],
    email = user_dict["email"],

  static final class BasicAuthInterceptor implements Interceptor {
    private final String credentials;
    private final String host;

    BasicAuthInterceptor(String host, String username, String password) {
      this.credentials = Credentials.basic(username, password);
      this.host = host;
    }

    @Override public Response intercept(Chain chain) throws IOException {
      Request request = chain.request();

     *
     * @param form the create form
     * @param username the current username
     * @param currentTime the current time
     * @return optional file configuration entity
     */
    public static OptionalEntity<FileConfig> getEntity(final CreateForm form, final String username, final long currentTime) {
        switch (form.crudMode) {
        case CrudMode.CREATE:

     *
     * @param form the create form
     * @param username the current username
     * @param currentTime the current time
     * @return optional label type entity
     */
    public static OptionalEntity<LabelType> getEntity(final CreateForm form, final String username, final long currentTime) {
        switch (form.crudMode) {
        case CrudMode.CREATE:

```Python
UserInDB(**user_dict)
```

다음과 같은 결과를 생성합니다:

```Python
UserInDB(
    username="john",
    password="secret",
    email="******@****.***",
    full_name=None,
)
```

혹은 더 정확히 말하자면, `user_dict`를 직접 사용하는 것은, 나중에 어떤 값이 추가되더라도 아래와 동일한 효과를 냅니다:

```Python
UserInDB(
    username = user_dict["username"],
    password = user_dict["password"],
    email = user_dict["email"],

							<c:choose>
								<c:when test="${!empty username && username != 'guest'}">
									<li class="nav-item">
										<div class="dropdown">
											<a id="userMenu" class="nav-link dropdown-toggle" data-bs-toggle="dropdown"
												href="#" role="button" aria-haspopup="true"
												aria-expanded="false"> <i class="fa fa-fw fa-user" aria-hidden="true"></i>${username}
											</a>

@ExtendWith(MockitoExtension.class)
class NtlmContextTest {

    @Mock
    private NtlmPasswordAuthentication mockAuth;

    private final String domain = "TEST_DOMAIN";
    private final String username = "testUser";
    private final String password = "testPassword";
    private final String workstation = "TEST_WORKSTATION";

    @BeforeEach
    void setUp() {
        // MockitoExtension handles mock initialization

					<c:choose>
						<c:when test="${!empty username && username != 'guest'}">
							<li class="nav-item">
								<div class="dropdown">
									<a id="userMenu" class="nav-link dropdown-toggle" data-bs-toggle="dropdown"
										href="#" role="button" aria-haspopup="true"
										aria-expanded="false"> <i class="fa fa-fw fa-user" aria-hidden="true"></i>
										<span>${username}</span>
									</a>

				<la:form styleId="login" method="post">
					<div class="input-group mb-3">
						<c:set var="ph_username">
							<la:message key="labels.login.placeholder_username" />
						</c:set>
						<la:text property="username" styleId="username"
							class="form-control" placeholder="${ph_username}" />
						<div class="input-group-append">
							<span class="input-group-text">
								<em class="fa fa-user fa-fw">
            				</span>

Zum Beispiel stellt eine der Möglichkeiten, die OAuth2-Spezifikation zu verwenden (genannt „password flow“), die Bedingung, einen `username` und ein `password` als Formularfelder zu senden.

Die <abbr title="Specification – Spezifikation">Spec</abbr> erfordert, dass die Felder exakt `username` und `password` genannt werden und als Formularfelder, nicht JSON, gesendet werden.
