type this command
Code:
sudo gedit /etc/samba/smb.conf
into the terminal and type your password when it asks. Then scroll down to the "authentication" section and find where it says something like "security = usr" (not sure if thats exactly what it is, its been months since I changed it) and change it to "security = share"
After that type this command
Code:
sudo /etc/init.d/samba restart
Then test it out and let me know how it goes.
