This issue is happening from last few weeks and I have no solution on this as of now.
We have had around 6 mac so far that have had issues with their User account not showing at the Login Window. These are mobile accounts (AD Users), all this mac has Filevault enabled via a policy from JSS. When we restart this mac, it will only show Local Admin User and other Mobile User accounts will only show up once we Login from Local Admin and log out local admin.
All this mobile user account (AD User) are still present in the Users & System Preference and the home folder is also available.
Please suggest on any solution
