Is this possible and if it is how?
No, it is not possible to create automatically users without passwords.
You can create batch of users, then use console command to set blank password for all created users.

IM not sure about his setup.. so this is a stab in the dark but it can be done with out password.. -Jordan
It is not possible to create batch for MAC-Authentication.
MAC-Authentication requires correct MAC-address for username field.
Batch creates random characters for username, so it could be used for login+password authentication.
I solve the way how to create 10,000 “users”, manual work is not a option 
I do it with PHP and telnet solution
