Our staging server has been neglected for a while, and I'm trying to get it back to as close as production as I can. I'm trying to setup profile sync and I've used the same accounts for production and I'm not pulling any accounts back.
We don't use profile sync to export back to AD so I figured using the synchronization service wasn't necessary. After not getting any accounts back I switched it to use the sync service and still no results.
EDIT: The ultimate goal would be to get staging setup without profile sync service, since from what I've read the service is not required if you never export back to AD, and eventually setup production the same way.
