Hi, Today I encountered an issue where after re-installing a Guix System, I couldn't add a new printer anymore. Any CUPS client (including the trusty localhost:631 HTTP page) would loop on authenticating my user.
After consulting the logs and finding this kind of line: --8<---------------cut here---------------start------------->8--- pam_authenticate() returned 7 (Authentication failure) --8<---------------cut here---------------end--------------->8--- I started looking at our PAM configuration for CUPS, but we currently have none, which is probably the issue. Using 'cups-minimal' instead of cups (which is built with linux-pam) solves the issue, as the 'cups' value provided to the <cups-configuration> record. We should probably make cups-minimal the default, or extend our pam-service-type with the relevant PAM entries. Thoughts/takers? -- Thanks, Maxim
