Hi,
Using RedHat there is an directory called /etc/skel which is copied
to user directory when a new user is created. We used this that every
user has the same preconfigured desktop. So you can copy your
.kde directory to /etc/skel. Every new created user will than have at
startup the same KDE configuration.
Another way is to copy your .kde directory directly to the other user,
then you have to change manually all permissions to the other user.
Hope this helps a bit
