This issue persists in lightdm 1.30.0-0ubuntu3.1 in Ubuntu focal. I see the warnings not only for pam_kwallet.so, but also its successor pam_kwallet5.so, as well as pam_gnome_keyring.so (which I do not have installed). All three of these are referenced in /etc/pam.d/lightdm and /etc/pam.d/lightdm-greeter as "optional" modules.
I attempted to eliminate the warnings by replacing the "optional" keyword with "[success=ok module_unknown=ignore default=ignore]", but that had no visible effect. The entries referring to these modules need to be removed from LightDM's PAM config files. If libpam-gnome-keyring is installed, it will already make itself known to PAM via a pam-auth-update profile, which is the correct approach. The libpam-kwallet5 package has no pam-auth-update profile, but that is an issue for that package, not this one. ** Tags added: focal -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to lightdm in Ubuntu. https://bugs.launchpad.net/bugs/1404172 Title: lightdm: PAM unable to dlopen(pam_kwallet.so): /lib/security/pam_kwallet.so: cannot open shared object file: No such file or directory Status in One Hundred Papercuts: Confirmed Status in Light Display Manager: Confirmed Status in systemd: New Status in lightdm package in Ubuntu: Confirmed Bug description: auth.log complaints: Dec 19 07:24:42 u32 lightdm: PAM unable to dlopen(pam_kwallet.so): /lib/security/pam_kwallet.so: cannot open shared object file: No such file or directory Dec 19 07:24:42 u32 lightdm: PAM adding faulty module: pam_kwallet.so Dec 19 07:24:42 u32 lightdm: pam_unix(lightdm-greeter:session): session opened for user lightdm by (uid=0) Dec 19 07:24:42 u32 systemd-logind[656]: New session c1 of user lightdm.
