Comment 6 for bug 788167

Same with Trusty. The script mentioned here, http://ubuntuforums.org/showthread.php?t=2176738, does work. If you've installed your samba printer, then replace the symlink /usr/lib/cups/backend/smb (point to /usr/bin/smbspool) with the scipt mentioned in the link, authenticated printing over samba with kerberos works. It only has one problem. After replacing the symlink /usr/lib/cups/backend/smb with the script from the link, it becomes impossible to install samba printers either through cups or the GUI. Replace the script with the original symlink to /usr/bin/smbspool and you can install samba printers again. I would really like a good solution for this, since we now have to option to either print or to install a printer, but not both.
