Samba is a great tool to share files and folders between computers. Distributions that emphasize ease-of-use, such as Ubuntu, offer comfortable graphical user interfaces to share folders with a few mouse clicks. However, if you, like me, are not a professional network administrator, it is easy to overlook that Samba requires you to set up user permissions correctly at four different places. If you omit one, you will experience lots of ‘access denied’ and other errors.
