Neste exemplo utilizamos cabeçalhos personalizados inventados `X-Keys` e `X-Token`.

Mas em situações reais, como implementações de segurança, você pode obter mais vantagens em usar as [Ferramentas de segurança integradas (o próximo capítulo)](../security/index.md){.internal-link target=_blank}.

MinIO recommends using Linux operating system for production workloads.

- Objects must not have conflicting objects as parent objects, applications using this behavior should change their behavior and use non-conflicting unique keys, for example situations such as following conflicting key patterns are not supported.

#### About `**user_dict`

`UserInDB(**user_dict)` means:

*Pass the keys and values of the `user_dict` directly as key-value arguments, equivalent to:*

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

    implements SortedMap<K, V> {

  @SuppressWarnings("unchecked")
  static final Comparator<?> NATURAL_ORDER = Ordering.natural();

  // This reference is only used by GWT compiler to infer the keys and values
  // of the map that needs to be serialized.
  private @Nullable Comparator<? super K> unusedComparatorForSerialization;
  private @Nullable K unusedKeyForSerialization;
