  To protect your rights, we need to make restrictions that forbid
distributors to deny you these rights or to ask you to surrender these
rights.  These restrictions translate to certain responsibilities for
you if you distribute copies of the library or if you modify it.

MinIO supports multiple long term users in addition to default user created during server startup. New users can be added after server starts up, and server can be configured to deny or allow access to buckets and resources to each of these users. This document explains how to add/remove users and modify their access rights.

## Get started

When configured, MinIO sends request and credential details for every API call to an external HTTP(S) endpoint and expects an allow/deny response. MinIO is thus able to delegate access management to an external system, and users are able to use a custom solution instead of S3 standard IAM policies.

MinIO supports multiple admin users in addition to default operator credential created during server startup. New admins can be added after server starts up, and server can be configured to deny or allow access to different admin operations for these users. This document explains how to add/remove admin users and modify their access rights.

  `I didn't!' the March Hare interrupted in a great hurry.

  `You did!' said the Hatter.

  `I deny it!' said the March Hare.

  `He denies it,' said the King:  `leave out that part.'

  `Well, at any rate, the Dormouse said--' the Hatter went on,
looking anxiously round to see if he would deny it too:  but the
Dormouse denied nothing, being fast asleep.

Da wir in diesem Fall (ohne die Verwendung von `Annotated`) den Parameter-Defaultwert `None` mit `Query()` ersetzen, müssen wir nun dessen Defaultwert mit dem Parameter `Query(default=None)` deklarieren. Das dient demselben Zweck, `None` als Defaultwert für den Funktionsparameter zu setzen (zumindest für FastAPI).

Sprich:

```Python
q: Union[str, None] = Query(default=None)
```

... macht den Parameter optional, mit dem Defaultwert `None`, genauso wie:
