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.

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.

https://bugzilla.redhat.com/show_bug.cgi?id=1881630 Bug ID: 1881630 Summary: ipatests-only: kinit_as_user should collect kdcinfo.REALM on failure Product: Red Hat Enterprise Linux 8 Version: 8.3 Status: NEW Component: ipa Assignee: twoerner(a)redhat.com Reporter: fcami(a)redhat.com QA Contact: ipa-qe(a)redhat.com CC: abokovoy(a)redhat.com, atikhono(a)redhat.com, extras-qa(a)fedoraproject.org, jhrozek(a)redhat.com, lslebodn(a)redhat.com, mzidek(a)redhat.com, nalin(a)redhat.com, npmccallum(a)redhat.com, pbrezina(a)redhat.com, rcritten(a)redhat.com, rharwood(a)redhat.com, sbose(a)redhat.com, ssorce(a)redhat.com, sssd-maintainers(a)lists.fedoraproject.org, tibbs(a)math.uh.edu, tscherf(a)redhat.com Depends On: 1850445 Target Milestone: rc Classification: Red Hat Pool ID: sst_identity_management_rhel_8 When requesting a tgt fails after a password reset, collecting: /var/lib/sss/pubconf/kdcinfo.$REALM will help determine how SSSD was selecting which KRB5KDC to use. See https://pagure.io/freeipa/issue/8510 for details. +++ This bug was initially created as a clone of Bug #1850445 +++ kinit switches KDC for each action. It would be better if it kept track of which KDC to use, because on password change, it sometimes contacts one KDC to change the password and then another one, immediately, to get a TGT, which fails because replication between the two KDCs has not completed yet.

If yes, can you check if /var/lib/sss/pubconf/kdcinfo.IPA.TEST exists and contains one or more IP addresses of IPA servers? This file is read by SSSD's locator plugin which should make sure libkrb5 uses the same KDC for a long time. bye, Sumit --- Additional comment from François Cami on 2020-06-24 16:22:57 UTC --- Hi Sumit, The machine logs for the test are available at: http://freeipa-org-pr-ci.s3-website.eu-central-1.amazonaws.com/jobs/3966b69… The timestamp for the error is 1592990743.325347 (Wednesday, June 24, 2020 9:25:43.325 AM) and the journal seems to imply SSSD was started at this point. Sadly the VMs used for the test are ephemeral and the above test fails only sporadically. I will add a step to display /var/lib/sss/pubconf/kdcinfo.IPA.TEST similarly to the way I added KRB5_TRACE=/dev/stdout to get more information. Thanks, François --- Additional comment from Robbie Harwood on 2020-06-25 19:09:32 UTC --- Would also like to see the sssd information. (I will note that krb5 expects there to be a single master_kdc that is authoratative for password changes. If that address resolves to multiple KDCs, they need to agree on the state of the world.) --- Additional comment from François Cami on 2020-06-25 19:36:57 UTC --- Robbie, do you need more information than what is seen in the PR: https://github.com/freeipa/freeipa/pull/4853 Especially: https://github.com/freeipa/freeipa/pull/4853#issuecomment-649235842 The test blows up very sporadically. I've triggered it 16 times today without any issue. If within a month I haven't seen it red, I will trigger a 100+ run and we might get a bad run with interesting logs. --- Additional comment from Robbie Harwood on 2020-06-25 20:51:09 UTC --- Ah sorry, race condition - I started my comment before yours appeared. I've subscribed to the issue. Per #c3, I think that master_kdc isn't being correctly used - it seems like Sumit is investigating where the multiple values come from. --- Additional comment from Sumit Bose on 2020-06-26 11:30:23 UTC --- (In reply to Robbie Harwood from comment #5) > Ah sorry, race condition - I started my comment before yours appeared. I've > subscribed to the issue. Per #c3, I think that master_kdc isn't being > correctly used - it seems like Sumit is investigating where the multiple > values come from. Hi, in the current logs there was only one IP address and this will be used for the master as well. As long there is a kdcinfo file SSSD's Kerberos locator plugin should use the data and iirc libkrb5 will always ask the available locator plugins first before trying other methods to find a KDC. Since the KRB5_TRACE output in the description has e.g. 'Sending DNS URI query for _kpasswd.IPA.TEST.' I would expect that the kdcinfo file did not exist in this run. Maybe SSSD had some delays when trying to connect to the IPA server and as a result the creation of the kdcinfo file was delayed as wel? bye, Sumit --- Additional comment from Robbie Harwood on 2020-09-10 17:31:13 UTC --- Moving to sssd based on #c6. --- Additional comment from François Cami on 2020-09-22 18:58:49 UTC --- ipatests PR to collect that kdcinfo file: https://github.com/freeipa/freeipa/pull/5128 Referenced Bugs: https://bugzilla.redhat.com/show_bug.cgi?id=1850445 [Bug 1850445] kinit switches servers after password change -- You are receiving this mail because: You are on the CC list for the bug.

[Bug 1887077] New: Incorrect password expiry warning

https://bugzilla.redhat.com/show_bug.cgi?id=1887077 Bug ID: 1887077 Summary: Incorrect password expiry warning Product: Fedora Version: 33 Status: NEW Component: sssd Severity: high Assignee: sssd-maintainers(a)lists.fedoraproject.org Reporter: james(a)ettle.org.uk 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: These are all Fedora 33 machines set up as IPA clients in a local realm. When I log into the F33 machines I see a message like: Warning: your password will expire in 32767 days. The expiry time isn't always consistent. Simultaneously, on another machine I see Warning: your password will expire in 32765 days. All machines have their clocks synchronised. The password actually expires in 21 days. The inconsistency of the reported number, and the fact that the value is always a few short of 2^15, makes me wonder if this message is coming from a faulty printf() formatter somewhere. I don't see this on the Fedora 32 machines. Reporting against sssd to kick off investigation; not sure exactly which component is at fault. Version-Release number of selected component (if applicable): sssd-2.3.1-4.fc33.x86_64 pam-1.4.0-4.fc33.x86_64 freeipa-client-4.8.10-5.fc33.x86_64 -- You are receiving this mail because: You are on the CC list for the bug.
