In short, prior to 1st of april 2015, you required
- a FIM server license for every FIM server installed and a CAL for every user managed in the FIM Service, or
- Forefront Identity Manager 2010 R2 External Connector
After 1st of april 2015:
- Windows Server license (Standard & Datacenter) will include FIM server entitlement
- FIM Server 2010 R2 licenses will not be available anymore on the price lists
The FIM server will no longer be sold as a separate license, but instead Windows Server licenses will allow customers to install the FIM Server software.
Azure Active Directory Premium (AADP) and any suite that contains AADP, including Enterprise Mobility Suite (EMS) and Enterprise Cloud Suite (ECS), will also entitle users to access FIM.
Since FIM users already required a Windows Server CAL or equivalent to access FIM running on Windows Server, no additional Windows Server CALs (or Windows Server External Connector) will be required.
