Change which PAM config file kcheckpass uses

[Andrew Martin]

Hello,

By default on Debian-based systems, kcheckpass (used by kscreenlocker_greet)
uses /etc/pam.d/common-auth, but I would like to define a separate PAM
configuration for kcheckpass. Would I just need to create 
/etc/pam.d/kcheckpass, or do something else?

Thanks,

Andrew
