I just read through the documentation for user management and I'm missing a fundamental understanding of some aspect of it. I want to create an admin user instead of doing everything as root. I created a user 'brian' and added them to the Adminstrators group. However, I cannot log in as that user. If I go to permissions→users→password and try and change the password for user 'brian' I get an error that the user doesn't exist, despite the user showing up as the only other user other than root. I created an administrator pool and added all my Vms and storage. Is there something I need to do to actually 'activate' a user?
