On the first login to a Big Sur (or later) mac (either clean install or OS upgrade), user’s will be presented with the following dialog boxes to “sync” their passwords one time:
If these boxes keep coming up at login after the user has gone through them all once – this means that there is some problem with the user’s Active Directory password.
To solve this problem, please do the following:
1 – Have the user change their UM password at https://password.it.umich.edu
2 – On the Mac, open System Preferences → Users & Groups and have the user change their computer password to the new UM password.
3 - Restart the Mac to confirm the user can unlock/log-in to the mac with the new password
4 – The Enterprise Connect dialog boxes will come up again – but when the user goes through them one more time to “sync” the passwords – that should be it!
