https://bugzilla.redhat.com/show_bug.cgi?id=2372533 Bug ID: 2372533 Summary: Use `systemctl kill` in logrotate postrotate script Product: Fedora Version: 42 OS: Linux Status: NEW Component: sssd Severity: low Assignee: sssd-maintainers(a)lists.fedoraproject.org Reporter: marcosfrm(a)gmail.com QA Contact: extras-qa(a)fedoraproject.org CC: abokovoy(a)redhat.com, atikhono(a)redhat.com, lslebodn(a)redhat.com, pbrezina(a)redhat.com, sbose(a)redhat.com, ssorce(a)redhat.com, sssd-maintainers(a)lists.fedoraproject.org Target Milestone: --- Classification: Fedora `systemctl kill` leverages systemd's knowledge of the daemon's main PID, eliminating the need to rely on PID files or external tools like `killall` or `pkill`. This ensures precise signal sending to the intended process, reducing the risk of errors in process identification. Additionally, using `systemctl kill` logs the signal sending in the service's journal, providing a record of actions taken. Requires selinux-policy-41.43 or higher (see https://bugzilla.redhat.com/show_bug.cgi?id=2369644) available as an update for F41, F42, and Rawhide. https://bodhi.fedoraproject.org/updates/FEDORA-2025-eb98eb9e24 (F41 -- will go to stable in a few days) https://bodhi.fedoraproject.org/updates/FEDORA-2025-f9f097f491 (F42 -- stable) https://bodhi.fedoraproject.org/updates/FEDORA-2025-3db4c0ec1c (Rawhide) The logrotate configuration snippet: # cat /etc/logrotate.d/sssd /var/log/sssd/*.log { weekly missingok notifempty sharedscripts rotate 2 compress delaycompress su sssd sssd postrotate /bin/kill -HUP `cat /run/sssd/sssd.pid 2>/dev/null` 2> /dev/null || true /bin/pkill -HUP sssd_kcm 2> /dev/null || true endscript } In the postrotate script, kill and pkill can be replaced by: /usr/bin/systemctl kill --signal=HUP --kill-whom=main sssd.service sssd-kcm.service 2>/dev/null || true Because: # systemctl show -P MainPID sssd.service 1225 # cat /run/sssd/sssd.pid 1225 # systemctl show -P MainPID sssd-kcm.service 1447 # pgrep sssd_kcm 1447 Reproducible: Always Additional Information: sssd-common-2.11.0-1.fc42.x86_64 -- You are receiving this mail because: You are on the CC list for the bug.

[Bug 1886841] New: Pinpad card reader for login authentication yet you are asked also enter pin on pc keyboard
by bugzilla＠redhat.com 06 May '26

https://bugzilla.redhat.com/show_bug.cgi?id=1886841 Bug ID: 1886841 Summary: Pinpad card reader for login authentication yet you are asked also enter pin on pc keyboard Product: Fedora Version: 32 Hardware: x86_64 URL: https://lists.fedoraproject.org/archives/list/freeipa- users(a)lists.fedorahosted.org/thread/FLLIA5RLHT3MO4NI2F 3MJNMBBNGGZA4Z/ OS: Linux Status: NEW Component: sssd Severity: high Assignee: sssd-maintainers(a)lists.fedoraproject.org Reporter: peter(a)unix-edu.se QA Contact: extras-qa(a)fedoraproject.org CC: abokovoy(a)redhat.com, atikhono(a)redhat.com, jhrozek(a)redhat.com, lslebodn(a)redhat.com, mzidek(a)redhat.com, pbrezina(a)redhat.com, rharwood(a)redhat.com, sbose(a)redhat.com, ssorce(a)redhat.com, sssd-maintainers(a)lists.fedoraproject.org Target Milestone: --- Classification: Fedora User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:68.0) Gecko/20100101 Firefox/68.0 Build Identifier: Hello Folks! We are working on getting smart card authentication working using pinpad card readers for improved security. To do this we use: FreeIPA Server is running on Fedora 32 with latest updates. FreeIPA Clients is Fedora 32 Workstation installed on pc with latest updates with connected usb card reader. The card reader is Gemalto CT700 with pinpad, we use several user individual SmartCard HSM 4K with FreeIPA signed certificates on them. FreeIPA Clients run OpenSC and are configured to use smartcard certificate based authentication, setup per Smartare HSM best practice. Further clients are using SSSD and not PAM_PKCS#11. All working great using smartcard for authentication, as long not enabling the pinpad in opensc. If doing so we are prompted for the PIN not only in the pinpad reader but also GDM prompts you to enter PIN on keyboard. Expected result is to be logged in directly after entering correct PIN code on pinpad reader, not being prompted by GDM to enter PIN on keyboard as well. If enabling pinpad in opensc, login gets a bit odd: 1. Fedora 32 Workstation GDM menu prompts a few users that can login. 2. Smartcard is inserted in reader. 3. GDM blanks out the screen and smartcard reader prompts to enter PIN in its lcd display. 4. Entering pin on smartcard reader followed by pressing ok button on smartcard reader at getting result Pin OK in reader display. 5. GDM now prompts for entering PIN on keyboard, this is unexpected, instead of directly being logged in to the window manager, here Gnome (or xfce, whatever window manager you selected to use). 6. You have to enter the PIN now on keyboard, followed by hitting enter. 7. Once again smartcard reader now prompts for PIN in its lcd display. 8. Entering PIN on the smartcard pinpad reader followed by pressing pinpad ok button. 9. You are now logged in, and all is normal. If ripping out the smartcard from reader the screen locks, as expected. Sometimes, but not always, you are logged in to window manager directly after step 5. What could this be, anyone who have seen this before or know how to set it up ? Reproducible: Always Steps to Reproduce: 1. Install and setup FreeIPA server and client on Fedora32 latest updates to use smartcard authentication for login. Work on IPA Server: ------------------- Install Fedora 32 server minimal installation all excluded, update to latest version (dnf update -y), set hostname, enter server hostname (ipaserver.mydomain.com) and ip in /etc/hosts, enable and start chrony, reboot. (As root user) dnf install ipa-server bind-dyndb-ldap ipa-server-dns -y for SERVICES in ntp http https ldap ldaps kerberos kpasswd dns; do firewall-cmd --permanent --add-service=$SERVICES; done ipa-server-install --setup-dns . . .

(as root user) dnf install freeipa-client.x86_64 -y ipa-client-install --mkhomedir id user3 reboot Connect gemalto CT700 card reader to pc/Fedora Workstation. lsusb dnf install opensc ccid pcsc-tools -y systemctl enable pcscd systemctl start pcscd scp user3@ipaserver:/tmp/config-client-for-smart-card-auth.sh . chmod +x config-client-for-smart-card-auth.sh ./config-client-for-smart-card-auth.sh /etc/ipa/ca.crt . . . In /etc/opensc.conf enable pinpad by uncommenting enable_pinpad = true; Ensure pam_cert_auth is true in sssd.conf: grep ^pam_cert_auth /etc/sssd/sssd.conf pam_cert_auth = True authselect select sssd with-mkhomedir with-sudo with-smartcard with-smartcard-lock-on-removal --force authselect current reboot 2.

Now try login to workstation.mydomain.com using GDM using the smartcard issued for user3 Note! user3 password must not have been expired, it should be fixed by the initial login test above. As per details above: 1. Fedora 32 Workstation GDM menu prompts a few users that can login. 2. Smartcard is inserted in reader. 3. GDM blanks out the screen and smartcard reader prompts to enter PIN in its lcd display. 4. Entering pin on smartcard reader followed by pressing ok button on smartcard reader at getting result Pin OK in reader display. 5. GDM now prompts for entering PIN on keyboard, this is unexpected, instead of directly being logged in to the window manager, here Gnome (or xfce, whatever window manager you selected to use). 6. You have to enter the PIN now on keyboard, followed by hitting enter. 7. Once again smartcard reader now prompts for PIN in its lcd display. 8. Entering PIN on the smartcard pinpad reader followed by pressing pinpad ok button. 9. You are now logged in, and all is normal. If ripping out the smartcard from reader the screen locks, as expected. Sometimes, but not always, you are logged in to window manager directly after step 5. Actual Results: You are asked to enter PIN using pinpad on card reader followed by enter PIN using the keyboard, then you are logged in. Sometimes you need to enter PIN on pinpad once more after entering PIN using the keyboard. Expected Results: Directly after entering correct PIN using pinpad on card reader you should be logged in.
