This is a Python function.

It will be called by **FastAPI** whenever it receives a request to the URL "`/`" using a `GET` operation.

In this case, it is an `async` function.

You could also define it as a normal function instead of `async def`:

     *
     * @param authorityServerName
     *            The hostname of the server that should be queried. For maximum efficiency this should be the hostname
     *            of a domain controller however a member server will work as well and a domain controller may not
     *            return names for SIDs corresponding to local accounts for which the domain controller is not an
     *            authority.
     * @param tc

And we are using this model to declare our input and the same model to declare our output:

Now, whenever a browser is creating a user with a password, the API will return the same password in the response.

In this case, it might not be a problem, because it's the same user sending the password.

### API

By default, there is no limitation on the number of concurrent requests that a server/cluster processes at the same time. However, it is possible to impose such limitation using the API subsystem. Read more about throttling limitation in MinIO server [here](https://github.com/minio/minio/blob/master/docs/throttle/README.md).

KEY:

     *
     * @param authorityServerName The hostname of the server that should be queried. For maximum efficiency this should be the hostname of a domain controller however a member server will work as well and a domain controller may not return names for SIDs corresponding to local accounts for which the domain controller is not an authority.

   * is unnecessary; for example, {@code copyOf(copyOf(anArrayList))} will copy the data only once.
   * This reduces the expense of habitually making defensive copies at API boundaries. However, the
   * precise conditions for skipping the copy operation are undefined.
   *
   * @throws NullPointerException if any of {@code elements} is null
   * @since 7.0 (source-compatible since 2.0)
