I've been searching for an answer to this for a bit now - my apologies if this has been already asked and answered.
I used to be able to create local accounts via policy and use a blank password, definitely in the 8.x JSS and likely in early 9.x builds. I'm not sure when this changed, but as of 9.22, I am not able to do this.
I was editing an existing post-imaging policy that used to deploy a local "student" account with a blank password to scope it to a new set of machines, and the policy won't save (user password is now required to be non-blank).
Is there a method to create users with blank login passwords via the policy GUI?
