I have a user that I can't get to sync over to the appliance at all. I've verified that they have a uniqueID value that matches their username just like other users who work fine. I've had to fix a few user accounts that were missing the uniqueID value already and that allowed them to sync over fine, but this one user just will not work. This is a relatively new account, but we have made quite a few new accounts recently and they have all synced up just fine.
