This is seen at least on the following scenario:
1-L2TP vpn environment using xl2tpd + pppd 
2-authentication method is PAP.
3-ppp version 2.4.5-5.1ubuntu2.2

The PAM  config auth line is automatically added to "common-auth" when 
installing the following package
libpam-smbpass:i386               2:4.1.6+dfsg-1ubuntu2
