Create a Samba User on Ubuntu
If you are using Samba Server on your network, you will want to create users that have access to use it. There’s a very simple command structure on how to do so.
I’m assuming that you’ve already installed Samba Server at this point.
There are two steps to creating a user. First we’ll run the smbpasswd utility to create a samba password for the user.
sudo smbpasswd -a <username>
Next, we’ll add that username to the smbusers file.
sudo gedit /etc/samba/smbusers
Add in the following line, substituting the username with the one you want to give access to. The format is <ubuntuusername> = “<samba username>”. You can use a different samba user name to map to an ubuntu account, but that’s not really necessary right now.
<username> = “<username>”
Now you can create samba shares and give access to the users that you listed here.
