I can confirm it locally. Inside a Focal LXD container, install sssd 2.2.3-3ubuntu0.10 (the best way is to use pull-lp-debs here, since the version is not present in the archive anymore), then run "apt install sssd" to upgrade the package to 2.2.3-3ubuntu0.10, and try to run sssd_pam by hand:
# /usr/libexec/sssd/sssd_pam
/usr/libexec/sssd/sssd_pam: /lib/x86_64-linux-gnu/libsss_certmap.so.0: version `SSS_CERTMAP_0.2' not found (required by /usr/libexec/sssd/sssd_pam)
Thank you for taking the time to report this bug.
