Adding users to the Samba server


In the previous recipe, we installed the Samba server and created a public share accessible to everyone. In this recipe, we will learn how to add authentication to the Samba server and password protect shared directories.

Getting ready

You will need access to a root account or an account with sudo privileges.

Make sure that the Samba server is installed and running.

How to do it…

  1. Create a new user account. You can use any existing account or add a new Samba only account with the following command. Change smbuser to your desired username:

  2. Now, we need to allocate a Samba password to this new user. First, enter your sudo password, followed by the new password for your Samba account, and then verify the password:

    $ sudo smbpasswd -a smbuser
    
  3. Create a shared directory for this user and change its ownership:

    $ sudo chown smbuser:smbuser /var/samba/share/smbuser...
