Hello, I'm having the same issue in 18.04 as well, also fixed it by adding `/var/lib/sss/pipes/private/pam wr,` to `/etc/apparmor.d/local/usr.sbin.cupsd`.
Confirmed both the issue and fix on 2 different machines (both on 18.04) and with 2 different AD accounts. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1558753 Title: AppArmor denying CUPS authentication against PAM on AD joined system (SSSD-based) To manage notifications about this bug go to: https://bugs.launchpad.net/apparmor/+bug/1558753/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
