Introduction

Here is a working cupsd.conf that we use to get CUPS 1.3.3 to work with Basic Auth.  We have not included any information on actually setting up PAM.  For most U*NIX servers, including Mac OS X, /etc/pam.d folder should contain a usable PAM configuration file named cups … if not then start at http://www.kernel.org/pub/linux/libs/pam/ to lean about PAM.
