Note that your system uses syslog. All of kdm's internally generated messages
(i.e., not from libraries and external programs/scripts it uses) go to the
daemon.* syslog facility; check your syslog configuration to find out to which
file(s) it is logged. PAM logs messages related to authentication to authpriv.*.
