How to use pam_kwallet?

After following a link from Stephan Binner's Blog I discovered the 
pam_kwallet package which seems to fix a long time KDE annoyance.
Currently I want to make an automatic connection to ICQ with kopete at login. 
The annoyance is that I have to enter the kwallet password after login to get 
the connection.

I changed /etc/pam,d/xdm as described in the README file. But somehow it does 
not work as expected. I still have to enter the kwallet password...

My system runs openSUSE 10.3 with KDE3 from the KDE:KDE3 repository.

Cheers
