**NOTE**: When configuring multiple OpenID based authentication providers on a MinIO cluster, any number of Role Policy based providers may be configured, and at most one JWT Claim based provider may be configured.

```

 * of the given providers. If no input provider is present, the output
 * provider will not be present. If more than one input provider
