### Using WebIdentiy API

On another terminal run `web-identity.go` a sample client application which obtains JWT id_tokens from an identity provider, in our case its Keycloak. Uses the returned id_token response to get new temporary credentials from the MinIO server using the STS API call `AssumeRoleWithWebIdentity`.

### 1. Fetch the root identity

As the initial step, fetch the private key and certificate of the root identity:

```sh
curl -sSL --tlsv1.2 \

## The key in the secret must be 'config.env'

## OpenID Identity Management
## The following section documents environment variables for enabling external identity management using an OpenID Connect (OIDC)-compatible provider.
## See https://min.io/docs/minio/linux/operations/external-iam/configure-openid-external-identity-management.html for a tutorial on using these variables.

authenticated through client credential grants provided by identity provider. Example providers include KeyCloak, Okta etc.

Calling AssumeRoleWithClientGrants does not require the use of MinIO default credentials. Therefore, client application can be distributed that requests temporary security credentials without including MinIO default credentials. Instead, the identity of the caller is validated by using a JWT access token from the identity provider. The temporary security credentials returned...
