### Enable Keycloak Admin REST API support

Before being able to authenticate against the Admin REST API using a client_id and a client_secret you need to make sure the client is configured as it follows:

- `account` client_id is a confidential client that belongs to the realm `{realm}`

In diese Exception fügen wir (falls vorhanden) die erforderlichen Scopes als durch Leerzeichen getrennten String ein (unter Verwendung von `scope_str`). Wir fügen diesen String mit den Scopes in den Header `WWW-Authenticate` ein (das ist Teil der Spezifikation).
