Using DEP enrollment with Mojave & Domain Bind & skip account creation at enrollment results in you not being able to login to a domain account as the login text fields are hidden as long as the device can communicate with the domain controller (text fields re-appear if no DC connectivity).
Can be worked around by installing a configuration profile to set display login to name and password. Not really sure what the best way to workaround this for now is since I don't want to control these settings for most users, probably doing something to add the device to an exclusion list after the AD user has logged in (or based off standard software all devices will have installed), I'm open to suggestions on a better way to do that.
Issue does not appear in High Sierra.
