In particular, the recommended flow of User-Managed Access (UMA) is not supported by any open source Solid Server implementation (yet). Current implementations rely on the access token issued by the OpenID Provider of the user to authenticate the user at a Solid Storage. A corresponding Group Note document that accurately reflects current implementations is being drafted by Christoph Braun.
