A few weeks ago Paul Loonen Architect @ Avanade delivered a Funcast about MIIS and how he could provision an AD from SQL database.
User lifecycle management using Microsoft Identity Integration Server (MIIS) is demonstrated. As such, HR information that is stored in SQL Server database will be used to manage user and group information in Microsoft Active Directory, including the provisioning and de-provisioning of such objects. It will be shown that all of this can be accomplished using a minimum of effort by leveraging the tools delivered with the MIIS platform.
Here is the recorded webcast.
