Because my customer doesn't want a new licence for a user who don't connect him self

More seroiusly, it s the same thing in odoo community. I have a docker on my mac for test purpose and yes, in odoo community, it's also a "user" which is the reference. That's an error IMHA because most off the company i know dont have to give access to their ERP to all their employees.

Because it is in the community apps, I think their is a mean to change that more easily but it's a big work to do and test.
