After adding a user to filevault via a Jamf policy, I'm still getting the message in the System Preferences UI "Some users are not able to unlock the disk"
The user that it shows when unlocking the preference pane, however, is indeed enabled, and I checked by running:
sudo fdesetup list
and also by logging in as that user at the FileVault login window.
Is this just a High Sierra UI bug? Or is something else going on here?
