This appears to have been addressed in bug #1949970 by making use of a feature of the PAM config. In /etc/pam.d/lightdm, I see e.g. -auth optional pam_gnome_keyring.so -auth optional pam_kwallet.so -auth optional pam_kwallet5.so >From the pam.conf(5) man page: If the *type* value from the list above is prepended with a - character the PAM library will not log to the system log if it is not possible to load the module because it is missing in the system. This can be useful especially for modules which are not always installed on the system and are not required for correct authentication and authorization of the login session. I'll mark this issue as a duplicate of the newer one, even though it should be the other way around. ** This bug has been marked a duplicate of bug 1949970 attempt to dlopen nonexistent pam_kwallet.so spams log -- 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.
