KDE config path

Hi,

I am trying to set KDE config search path on a kubuntu machine to:
/home/kib/.kde/share/config/:/etc/dmi/kde3/share/config/:/usr/share/kubuntu-default-settings/kde-profile/default/share/config/:/etc/kde3/
In that I expect /etc/kde3 to contain KDE default setup, 
/usr/share/kubuntu-default-settings/kde-profile/default/share/config/ 
the kubunto settings, and I want /etc/dmi/kde3/share/config to hold our 
customizations, and last have the users own settings.

But currently I can only get:
% kde-config --path config
/home/kib/.kde/share/config/:/etc/kde3/:/etc/dmi/kde3/share/config/:/usr/share/kubuntu-default-settings/kde-profile/default/share/config/

I have tried to fiddle with KDEDIRS and /etc/kderc but so far without 
success. Any suggestions??

The details of the current settings are below.

I have set /etc/kderc to read:
[Directories]
prefixes=/etc/dmi/kde3/,/usr/share/kubuntu-default-settings/kde-profile/default/,/etc/kde3/
userProfileMapFile=/etc/kde-user-profile

[Directories-default]
prefixes=/etc/dmi/kde3/,/usr/share/kubuntu-default-settings/kde-profile/default/
dir_config=/etc/kde3/

TIA,
Kim
