Samba config without auth

Sometimes its been necessary to have a completely auth-less samba share without any username and password dialog popup, especially when scripting in Windows. It took me some time to figure out the Samba config, below is a stripped example of a working authless share. Tested with Windows Server 2008 and Windows 7, using samba 3.

Bold parts is the important ones.
