Hi,
Following this guide to try and fix Sharepoint profile photo synchronization with active directory on our server:
http://blogs.technet.com/b/nishants/archive/2012/02/21/how-to-sync-picture-from-sharepoint-to-active-directory-and-hence-to-outlook-and-lync.aspx
After reaching the step...
"Under Add New Mapping, Choose the Source Data Connection as your AD import connection, attribute as "thumbnailPhoto" and Direction as "Export" and click Add"
...I cannot select a directory source (see screenshot).
