After that, you will be able to obtain an id_token for the Admin REST API using client_id and client_secret:

```
curl \
  -d "client_id=<YOUR_CLIENT_ID>" \
  -d "client_secret=<YOUR_CLIENT_SECRET>" \
  -d "grant_type=client_credentials" \
  "http://localhost:8080/auth/realms/{realm}/protocol/openid-connect/token"
```

    - Copy the OAuth Client Secret as the value for `<CLIENT_SECRET>`.
  - By default, `<IS_HOST>` is localhost. However, if using a public IP, the respective IP address or domain needs to be specified.
  - By default, `<IS_HTTPS_PORT>` has been set to 9443. However, if the port offset has been incremented by n, the default port value needs to be incremented by n.

Set `identity_openid` config with `config_url`, `client_id` and restart MinIO

```
~ mc admin config set myminio identity_openid config_url="http://CASDOOR_ENDPOINT/.well-known/openid-configuration" client_id=<client id> client_secret=<client secret> claim_name="tag"
```

> NOTE: As MinIO needs to use a claim attribute in JWT for its policy, you should configure it in casdoor as well. Currently, casdoor uses `tag` as a workaround for configuring MinIO's policy.

If you need to enforce it, use `OAuth2PasswordRequestFormStrict` instead of `OAuth2PasswordRequestForm`.

///

* An optional `client_id` (we don't need it for our example).
* An optional `client_secret` (we don't need it for our example).

/// info

The `OAuth2PasswordRequestForm` is not a special class for **FastAPI** as is `OAuth2PasswordBearer`.

依規範，實際上需要一個 `grant_type` 欄位且固定值為 `password`，但 `OAuth2PasswordRequestForm` 並不會強制檢查。

如果你需要強制檢查，請改用 `OAuth2PasswordRequestFormStrict` 取代 `OAuth2PasswordRequestForm`。

///

- 可選的 `client_id`（本例不需要）
- 可選的 `client_secret`（本例不需要）

/// info

`OAuth2PasswordRequestForm` 並不是像 `OAuth2PasswordBearer` 那樣對 **FastAPI** 來說的特殊類別。

`OAuth2PasswordBearer` 會讓 **FastAPI** 知道它是一個 security scheme，因此會以那種方式加入 OpenAPI。
