[Bug 1309535] Re: Running without pam-kwallet installed issues a warning in auth.log

[A. Denton]

I can confirm the problem with `journalctl`:

Jan 03 01:05:13 tron lightdm[12730]: PAM unable to dlopen(pam_kwallet.so): /lib/security/pam_kwallet.so: cannot open shared object file: No such file or dire

The lines were created during logins, i.e. initial logins or after
locking the screen (xflock4) and unlocking it again.

The workaround I used was to change /etc/pam.d/lightdm and /etc/pam.d
/lightdm-greeter and comment out (#) the following lines (in both
files):

#auth    optional        pam_kwallet.so
#auth    optional        pam_kwallet5.so
...
#session optional        pam_kwallet.so auto_start
#session optional        pam_kwallet5.so auto_start

So far the systemd log is clear of those loglines. A different
workaround would be to simply install  the KDE component.

Bug description:
  After upgrading to lightdm 1.10.0-0ubuntu2 I started to see this error
  in auth.log:

  Apr 10 14:34:54 simon-laptop lightdm: PAM unable to dlopen(pam_kwallet.so): /lib/security/pam_kwallet.so: cannot open shared object file: No such file or directory
  Apr 10 14:34:54 simon-laptop lightdm: PAM adding faulty module: pam_kwallet.so

  This seems like a regression because with lightdm 1.10.0-0ubuntu1 or
  before I didn't have this error showing. FYI, I don't have the pam-
  kwallet package installed.
