Same thing happened to me. Cannot login after upgrade to high sierra,
even if I hardwire to corp network. There is no local account on the
machine and IT admin is not able to login either. Need some serious
help!
Same issue happened to me. What's different is that even taking it to
work and connect to ethernet connection, the login still didn't
work.Took it to IT admin, they looked into it and was unable to login as
the admin account is also a network account...
