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.
