SharePoint 2010 synchronization is a two way process—import and export. As stated in the previous recipe, import/export is mutually exclusive and must be configured at the property level.
By default, all properties are import only. This is because when the first synchronization takes place, we want to populate the profile properties in SharePoint and not Active Directory.
As users work with the system and the data matures, it makes sense that some properties should be written back to Active Directory.
This recipe shows how to change the flow (import/export) of data for one property, Picture, to go from SharePoint to Active Directory.
You must have farm-level administrative permissions to the Central Administration site. There must be an instance of the User Profile Service running.
