If you run a command like sudo command, and you are not in the sudoers file, then you have the message # is not in the sudoers file. this incident will be reported. This is a normal situation

The $ indicates a different shell. If is possible that you have created a user with the useradd command instead of the adduser command. These two commands are different, since one creates the home directory, and the other does not create it.

Try to run /bin/bash to get the right shell. And recreate the user if needed (use the root login)

You must manually add the user to sudoers file or via usermoad -aG command in order to gain root privileges. Also, home directory must me setup in smb.conf file with template homedir directive.
