I have been following the HOWTO guide listed here to create my own domain server for my Windows XP Pro network. So far I've had some limited success, but I'm not quite there. My largest problem is that I cannot get CUPS to work correctly. Jobs just go to the printer and die a quiet death in queue. This is the output of my CUPS error_log file: I did have difficulty figuring out where the line: "AuthGroupName shadow" belonged in the /etc/cups/cupsd.conf file. I settled for a place in the <Location /admin> section, because that did give me access to the admin area of CUPS, although I suspect this is the wrong place. I cannot find a commented out AuthGroupName line to put this near. It is mentioned once in the "Security Options" directions, but placing it in that area results in an error message. Anyone have any help for me on this. I feel like I'm close, but that mythical cigar eludes me.
