The first thing you need to know is that to edit Samba's .conf file you'll need ';root'; privileges (similar to Administrator privileges in Windows). Unlike in Windows, where you'd have to sign in as the Administrator, Ubuntu doesn't let you sign into the ';root'; user. What you need to do is use something the ';sudo'; command, which will let you run programs as if you're the root user. To do this, open up a terminal window (like a command window in Windows) and type in the following:



sudo gedit /full-path-of-the-conf-file-you-want-to-?br>


and then hit enter. It will prompt you for a password, just enter your standard user password. Now, if you've entered the password correctly a text editor will open that will allow you to edit the conf file as you'd like. When you're finished, save and close as you normally would, which will take you back to the terminal window. Close the window, reboot the computer, and voila, it should work the way you want it to.
