Had anyone ever experienced this issue when an AD user tries to log into a freshly built machine and I go to Security & Privacy > Filevault > Padlock (Enter Admin Creds) > then click on enable users , you should get a window with the users that can be enabled and you click on their name and they enter their password , however when I click on Enable users nothing shows up so I'm unable to add the users to FV
