## Context
<!--- How has this issue affected you? What are you trying to accomplish? -->
<!--- Providing context helps us come up with a solution that is most useful in the real world -->

## Regression
<!-- Is this issue a regression? (Yes / No) -->
<!-- If Yes, optionally please include minio version or commit id or PR# that caused this regression, if you have these details. -->

```

In a given setup, there are `n` MinIO instances talking to `m` KES servers but only `1` central KMS. The most simple setup consists of `1` MinIO server or cluster talking to `1` KMS via `1` KES server.

```
export MINIO_IDENTITY_TLS_ENABLE=on
```

## Example

MinIO exposes a custom S3 STS API endpoint as `Action=AssumeRoleWithCertificate`. A client has to send an HTTP `POST` request to `https://<host>:<port>?Action=AssumeRoleWithCertificate&Version=2011-06-15`. Since the authentication and authorization happens via X.509 certificates the client has to send the request over **TLS** and has to provide
a client certificate.

```
minio server http://host{1...2}/export{1...8}
```

Expected expansion

```
> http://host1/export1
> http://host2/export1
> http://host1/export2
> http://host2/export2
> http://host1/export3
> http://host2/export3
> http://host1/export4
> http://host2/export4
> http://host1/export5
> http://host2/export5
> http://host1/export6
> http://host2/export6
> http://host1/export7

> NOTE: To deploy MinIO on with persistent storage, you must map local persistent directories from the host OS to the container using the `podman -v` option. For example, `-v /mnt/data:/data` maps the host OS drive at `/mnt/data` to `/data` on the container.

## macOS

Use the following commands to run a standalone MinIO server on macOS.
