This probably wont help, but I had similiar problem with usb memory stick.  I 
had  default in my fstab as an option.  According to manpage default includes 
nouser so user cant mount.  I removed the default option and that solved the problem.
I realize you are talking auto mounting and my comments may not apply. The 
distro that was involved was not ubuntu.
