NOTE: If `etcd` is configured with `Client-to-server authentication with HTTPS client certificates` then you need to use additional envs such as `MINIO_ETCD_CLIENT_CERT` pointing to path to `etcd-client.crt` and `MINIO_ETCD_CLIENT_CERT_KEY` path to `etcd-client.key` .

### 4. Test with MinIO STS API

Once etcd is configured, **any STS configuration** will work including Client Grants, Web Identity or AD/LDAP.
