I'm wondering if anyone has an idea to accomplish what I'm looking for, or if I just missed something with my current setup. I have a customer network that I would like to control using the Meraki Authentication, and using the User Management Portal to create user accounts with expiry dates. However, it appears that the user accounts must use an e-mail address, which won't do. I would like to create users with simply a username, and no e-mail. Is that possible with my setup? Or do I need to change to a different form of authentication?
