[Pkg-cups-devel] Bug#503214: cups: neither root privileges nor lpadmin membership is enough to install printer

[Marc Haber]

Package: cups
Version: 1.3.8-1lenny2
Severity: important

Hi,

I have always installed printers via the web frontend.
http://localhost:631/, authenticate with my user account (which is
member of the lpadmin group), and everything is fine.

Not today, "Unable to copy ppd file" is the error message, and my log
has:

E [23/Oct/2008:18:32:11 +0200] CUPS-Add-Modify-Printer: Unauthorized

This even happens when I use the root account to authenticate.

I have also noticed that a lot of files from the packages have
permission 600 now:

$ ls -al /usr/lib/cups/backend/ipp
-rwx------ 3 root root 25K 11. Okt 12:59 /usr/lib/cups/backend/ipp

which is violating a policy SHOULD, iirc.

What's going on on my system? How can I print?

Greetings
Marc
