We are going to assume you are a traditional home user, rather than an enterprise, and thus do not have any kind of directory service in place that manages your windows users. In this scenario, we need to create user accounts on our FreeNAS server which will be linked to our shared folders for authentication.
To create a user, we need to click Account, then Users, then Add User
A dialogue box should appear. Fill in a username, email address, and password. Then click the Microsoft Account
At the bottom of the dialogue box there should be an OK button that you need to click once you have finished.
You should now see your user in the users area of both the left side pane (if you expand Account and Users) and the main window.
Next time, we will create our Volumes and link our user to it.
