Was this tested as well? It's not clear to me from the comments above: * Ensure that other login/lockscreen options are still working as expected following the GDM test plan: https://wiki.ubuntu.com/DesktopTeam/TestPlans/GDM

Create user "test" 2. Configure sssd.conf: root@rmalz:/etc/sssd# cat sssd.conf [sssd] services = pam enable_files_domain = True certificate_verification = no_verification [certmap/implicit_files/test] matchrule = <SUBJECT>.* [pam] pam_cert_auth = True 3. Enable smart card login: pam-auth-update --disable sss-smart-card-required --enable sss-smart-card-optional * With these settings, login "test" user. Two problems will occurr. First, gnome-shell will not prompt for a smart card PIN and will continue to ask for password. This is caused by incorrect detection of default auth service, issue introduced with: gdm-util-Figure-out-default-service-from-service-definiti.patch Second, if first problem is fixed, login screen will freeze. This issue is caused by upstream bug [1]. * Ensure that other login/lockscreen options are still working as expected following the GDM test plan: https://wiki.ubuntu.com/DesktopTeam/TestPlans/GDM [Where problems could occur] * Upstream patch is changing behavior of finding conflicting sessions, possible risk of regression for non smart card cases * There is additional patch [3], introduced as part of fix for [1]. It seems that this patch is fixing presentation issue which is different from initial login problem and no part of this SRU. * Patches for both [2] and gdm-util-Figure-out-default-service-from-service-definiti.patch have been tested locally, allowing to login without issues.

After boot, GDM does not prompt for smartcard authentication correctly. It is possible to strike Esc and get GDM to prompt for a username and a smartcard PIN from the initial locked-out state, but this does not start a new desktop session and instead hangs. Striking Esc allows for the login to be attempted again, but with the same results. Syslog entries include unhandled promise rejections from the onSessionOpened event in loginDialog, and perhaps more importantly also from the user verification stack that is used to create the initial authentication options prompt (stack traces of the syslog entries attached). Affects GDM 46.0-2ubuntu1 in Noble. To reproduce, configure smartcard auth for a network user on a new Noble install and try to sign in.
