Unfortunately not with the first release. We are enabling alternative authentication methods with the next version, e.g. AD, so it will work with Dynamics CRM 2011 on-premise. We are interested in recruiting more people to try the on-premise version if you are interested. We need to know you authentication/security requirements and if any more entities are urgent. The first release included 40 entities for testing, the next release is still open so we can include more, for instance entities for the service module.
