This is due to us adding pam_kwallet to the configuration so that KDE
could work correctly with LightDM (bug bug 1305307). The warning occurs
in Ubuntu because you don't have pam-kwallet installed and PAM warns if
a module is not found (even if it is marked optional as in this case).
KDE users will have a similar warning about pam_gnome_keyring being
missing.

The only solutions I can think of are:
- Force users to install both libpam-gnome-keyring and pam-kwallet (seems excessive)
- Modify PAM not to report the error (but I don't think PAM can really tell if we expected the module to not exist).
- Use different PAM configuration for kubuntu/ubuntu (but then you can't log into both from the same install).
- ...

Give the warning is harmless I'm not proposing taking any action.

Title:
  Running without pam-kwallet installed issues a warning in auth.log

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.
