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.

Version-Release number of selected component (if applicable): Doesn't matter. Seen on RHEL 6 through 8, and on current Fedora. How reproducible: 100% Steps to Reproduce: 1. ipa-client-install 2. ssh -4 host.example.com Actual results: Connected via IPv6 Expected results: Connected via IPv4 Additional info: The bug is that sss_ssh_knownhostsproxy is configured on the client and that command doesn't respect the flags given to ssh. The issue affects all hosts, not just those part of the same FreeIPA domain. A practical effect of this is that connections get rejected or misbehave because of IP based rules in place for this connection. -- You are receiving this mail because: You are on the CC list for the bug.

[Bug 1965818] New: sssd - failing on "dotted"languages (Example turkish language)

https://bugzilla.redhat.com/show_bug.cgi?id=1965818 Bug ID: 1965818 Summary: sssd - failing on "dotted"languages (Example turkish language) Product: Fedora Version: 34 Hardware: x86_64 OS: Linux Status: NEW Component: sssd Severity: high Assignee: sssd-maintainers(a)lists.fedoraproject.org Reporter: thunderbirdtr(a)fedoraproject.org QA Contact: extras-qa(a)fedoraproject.org CC: abokovoy(a)redhat.com, atikhono(a)redhat.com, jhrozek(a)redhat.com, lslebodn(a)redhat.com, luk.claes(a)gmail.com, mzidek(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 Description of problem: Hello, SSSD Service isn't starting If we use dotted language in our system. For example, adding "LANG=tr_TR" into "/etc/sysconfig/sssd" makes sssd fails on start. If anyone install Fedora with "turkish" or other dotted language in their pc/laptop, that makes sssd fails on start. After I made little bit research, I notice this issue has been addressed multiple times around RHEL[0] and samba[1] and github[2] as well. So for that reason at least can we add "english" locale setting into rpm spec with "language" check as a workaround has been suggest in github link.That is at least gives us "working" package in dotted languge, and If anyone wants change setting, they can change it. At least for normal users, we can have working sssd service and not complain about fails all the times. I know this isn't the cleanest solution (proper solution is patching libldb package which causing this issue, but at least we can have a "quick&dirty" solution avoid on new installs. Thank you.

https://bugzilla.redhat.com/show_bug.cgi?id=1927907 Bug ID: 1927907 Summary: Latest release sssd 2.4.1 hard requires Python 3 Product: Fedora Version: 34 Status: NEW Component: sssd Assignee: sssd-maintainers(a)lists.fedoraproject.org Reporter: jlebon(a)redhat.com 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 Description of problem: It seems since the 2.4.1 rebase (https://src.fedoraproject.org/rpms/sssd/c/9e5dd4b66572aeb348f3cc854ce7fca9f…) sssd now pulls in python3 because it changed python3-sssdconfig from a "Suggests" to a "Requires". In Fedora CoreOS, we're trying to avoid shipping Python entirely to encourage containerizing user workloads and to keep the OS minimal. In a rawhide and f34 build, this package was identified as pulling it back in. Would it be possible to make it a weak dep again? This would also be useful in other environments like containers and custom OS builds which value minimalism. We can help with that if there's agreement. -- You are receiving this mail because: You are on the CC list for the bug. You are the assignee for the bug.

It is obviously a problem when trying to recover from a file system issue. Since logging is non-essential, sssd should just continue. At most is should emit a warning. $ touch /var/tmp/foo touch: cannot touch '/var/tmp/foo': Read-only file system $ sudo systemctl start sssd.service Job for sssd.service failed because the control process exited with error code. See "systemctl status sssd.service" and "journalctl -xe" for details.

Version-Release number of selected component (if applicable): sssd-2.3.0-2.fc33.x86_64 How reproducible: Deterministic Steps to Reproduce: 1. Make /var/log read-only, either by not remounting the filesystems rw, or by using udev.blockdev-read-only with systemd-246+ 2.

https://bugzilla.redhat.com/show_bug.cgi?id=1868696 Bug ID: 1868696 Summary: sssd_kcm loops on NFS server occasionally after an NFSv4.0 mount using Kerberos Product: Fedora Version: 32 Hardware: All OS: Linux Status: NEW Component: sssd Severity: high Assignee: sssd-maintainers(a)lists.fedoraproject.org Reporter: chuck.lever(a)oracle.com 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 Description of problem: Multi-homed Fedora 32 NFS client and server, both with keytabs. Sometimes after performing an NFSv4.0 mount, the sssd_kcm daemon on the server runs at 100% and fills up the sssd_kcm.log file (and eventually, the root partition).

Steps to Reproduce: 1. Set up NFS client and server with keytabs 2. Repeat: "mount -o vers=4.0,sec=sys" / do some operations / umount 3. Watch the server with "top" Actual results: Sometimes sssd_kcm goes to 100% of a CPU and must be killed. Expected results: No looping. Additional info: The NFSv4.0 backchannel, in this case, is secured with GSS krb5i. It appears that gssd on the server is accessing the Kerberos ticket cache while setting up the backchannel, and sometimes this triggers the kcm loop. -- You are receiving this mail because: You are on the CC list for the bug.
