Comment 10 for bug 1999884

I think we're talking of a different bug here though, because in your log here pam_sss via gdm-smartcard always returns an authentication failure:

Jan 31 22:22:25 lnx-ubu-2110 gdm-smartcard]: pam_sss(gdm-smartcard:auth): authentication failure; logname= uid=0
euid=0 tty=/dev/tty1 ruser= rhost= <email address hidden>
Jan 31 22:22:25 lnx-ubu-2110 gdm-smartcard]: pam_sss(gdm-smartcard:auth): received for user
<email address hidden>: 15 (Authentication service cannot retrieve user credentials)

While, in the initial description of this bug the problem was that pam_sss returned "success", but still `gdm-smartcard` was returning a failure:

Dec 16 10:26:22 ubu-vm-2022 gdm-smartcard]: pam_sss(gdm-smartcard:auth): authentication success; logname= uid=0 euid=0 tty=/dev/tty1 ruser= rhost= <email address hidden>

And this is the kind of error we're fixing here, so please in case the fix that is coming won't fix your case re-open a new bug against SSSD, because the bug we're fixing here is when:

1. pam_sss exits with success
2. gdm-smartcard still gives a permission error
