Hi all! I can confirm that with the latest kdelibs-bin from sarge (4:3.3.1-4 0) that the group of /etc/cups/cupsd.conf is changed from lpadmin to sys upon changing anything in the print-server dialogue box with kaddprinterwizard.
Additionally, kaddprinterwizard changes the DocumentRoot of the www interface to CUPS from the compiled-in default (/usr/share/cups/doc-root) to /usr/share/cups/doc,, breaking all the online help and all the images in the www admin interface (making it very hard to work out what is going on). Note that if the value of DocRoot is already set within the CUPS config file then the value is respected, it is just that the debian compilation of CUPS has a different set of default values for these variables than kaddprinterwizard. The result is that one has to make a decision to either *only* use kaddprinterwizard or *only* use the web interface to CUPS. At the least this should be *very* clearly enunciated to the user, but preferably they should play nicely with each other. thanks! Stuart
