[impact]

lightdm's pam.d config includes an attempt to dlopen pam_kwallet.so as well as pam_kwallet5.so, however pam_wallet.so comes from pam-kwallet which died around Trusty (https://launchpad.net/ubuntu/+source/pam-kwallet) while pam_kwallet5.so comes from kwallet-pam which provides only the newer '5' version, not the older unversioned library file.

This results in repeated spam error messages in the system log complaining about failure to load pam_kwallet.so

[test case]

install/enable lightdm and check system log at boot for messages like:

Nov 04 18:17:47 thrain lightdm[2510]: PAM unable to dlopen(pam_kwallet.so): /lib/security/pam_kwallet.so: cannot open shared object file: No such file or directory
Nov 04 18:17:47 thrain lightdm[2510]: PAM adding faulty module: pam_kwallet.so

[regression potential]

any regression would likely cause problems during login and/or missing or extra log messages during pam authentication.

[scope]

this is needed in all releases
