problem with gconfd

Hi friends
I am administrator of relatively big installation of SunRays with many 
users.
I would like to set some preferences in gnome (java) desktop as 
mandatory or default.
What is correct way to convert local user setting (created by graphical 
tool stored in
$HOME/.gconf) into default or mandatory setting.
Is there a way to find out from which resource gconfd loaded value of 
the key?
Both gconftool-2 and gconf-editor display value of keys but not from 
which repository
(mandatory, local, default) it was loaded.
Regards
Jan
