To run an extension, you must take some action that causes the extension to be called. This applies to both management agent extensions and Forefront Identity Manager Synchronization Service (FIM Synchronization Service) database (metaverse) extensions.
For a management agent extension, you must run the specific management action for which the extension is configured. For example, to cause the MapAttributesForImport method of the extension to be called, you must import data from the connector space into the metaverse by using the management agent.
For a metaverse extension, you must change connector space data in some way that causes the extension to be called. For example, to cause the Provision method of the extension to be called, you must affect a metaverse object in some way by modifying its attributes or by modifying, adding, or disconnecting a connector.
