samba - Jan 2013 - werr_access_denied when running setdriver for a printer

Hi all,

I'm getting WERR_ACCESS_DENIED error for some of the printers when running
setdriver printer_name printer_driver as part of the cupsaddsmb step.
Weirdly, it works for some printers, and never works for others, while all
the printers have the same settings. Samba 3.5.20 with CUPS 1.5.4.

Does this part of log give any clue of why could this happen?

function print_access_check() -- where does it take its data to check for
printer access?
