economical integration of big customers in Rainbow

We have several large accounts with in total round about 100,000 users.

Up to 500 users can be sensibly mapped as Enterprise Users. In order to win these customers as Rainbow users, all other users must be equipped with at least a free Rainbow variant.

All these customers use Microsoft Active Directory (MS-AD). Therefore it is a mandatory requirement that all Rainbow users are synchronized with MS-AD. This is today only possible in the Enterprise version.  Our customers are basically interested in Rainbow.

In order to generate concrete projects, the free Essential version must contain the MS-AD synchronization.
