- Initiate an id_token request to the WSO2 Identity Server, over a known [grant type](https://docs.wso2.com/display/IS540/OAuth+2.0+Grant+Types). For example, the following cURL command illustrates the syntax of an id_token request that can be initiated over the [Client Credentials Grant](https://docs.wso2.com/display/IS540/Client+Credentials+Grant) grant type.

## HTTP Trace

HTTP tracing can be enabled by using [`mc admin trace`](https://github.com/minio/mc/blob/master/docs/minio-admin-complete-guide.md#command-trace---display-minio-server-http-trace) command.

Example:

```sh
minio server /data
```

Default trace is succinct only to indicate the API operations being called and the HTTP response status.

```sh

### Transition Status

MinIO specific extension header `X-Minio-Transition` is displayed on `HEAD/GET` to predict expected transition date on the object. Once object is transitioned to the remote tier,`x-amz-storage-class` shows the tier name to which object transitioned. Additional headers such as "X-Amz-Restore-Expiry-Days", "x-amz-restore", and "X-Amz-Restore-Request-Date" are displayed when a object is under restore/has been restored to local MinIO cluster.

## TODO

- Richer progress UI is not present at the moment, this will be addressed in subsequent releases. Currently however a RATE of data transfer and usage increase is displayed via `mc`.
- Transitioned Hot Tier's as pooled setups are not currently supported, attempting to decommission buckets with ILM Transition will be rejected by the server. This will be supported in future releases.

`certgen` is a simple *Go* tool to generate self-signed certificates, and provides SAN certificates with DNS and IP entries:

```sh
./certgen -host "10.10.0.3,10.10.0.4,10.10.0.5"
```

A response similar to this one should be displayed:

```
2018/11/21 10:16:18 wrote public.crt
2018/11/21 10:16:18 wrote private.key
```

### 3.2 Use OpenSSL to Generate a Certificate

Use one of the following methods to generate a certificate using `openssl`:
