[kde-linux] kdm an pam

[Christian Häne]

Hello
I am using gentoo linux. I need a file in /etc/pam.d/ which only kdm uses. Now 
kdm uses the file /etc/pam.d/kde. All kde applications use /etc/pam.d/kde. 
Can you tell me how I can configure kdm to use an other file for 
example /etc/pam.d/kdm.
I need this to set up a fingerprint reader. I have to set different pam 
options in kdm then in the rest of kde.
