The context:
A client environment: SharePoint Foundation 2010
He wants to have a timerjob to update users profiles with data in active directory. Everything OK, I developed the timerjob that gets a catalog from active directory & updates selected fields for every user in the SharePoint hidden users list, that way I can keep a daily update for every user.
The problem: the client has used (as i should have thought) an active directory group that he have to manage permissions in SharePoint something like "All authenticated users".
Now i have no clue on how to update the profiles inside that group because they don't exist in the list.
Any ideas on where to update those profiles ?
