I'm trying to find the cause of my slow boot time and so I checked the log file and found this from the time of restart:
Feb 4 00:54:17 blackbird3460 lightdm: PAM unable to dlopen(pam_kwallet.so): /lib/security/pam_kwallet.so: cannot open shared object file: No such file or directory
Feb 4 00:54:17 blackbird3460 lightdm: PAM adding faulty module: pam_kwallet.so

Feb 4 00:54:17 blackbird3460 lightdm: pam_unix(lightdm-greeter:session): session opened for user lightdm by (uid=0)
What is that?
