question - login panel session selection

[Dany Cuyt]

We have a RedHat Linux 4 server with Gnome and KDE installed. Recently 
we decided to use Xfce as the default Desktop environment for our users.
I installed xfce 4.2.2. So far we are happy with Xfce and we managed to 
customize the environment to our user's needs. There is one thing I really
like to change but I'm unable to find how.
In the session selection the login panel offers:

    *  GNOME
    *  Xfce session
    *  Default system session
    *  Kde
    *  Failsafe terminal

By default, users will use Xfce. This has been accomplished with 
.Xclients-default and .Xclients in the $HOME directory of the user.
To make sure that users will use Xfce as desktop environment I would 
like to disable Gnome and Kde in the login panel session selection. But 
I don't want to remove kde or gnome from the system. Does anyone know 
how this can be done?

Thanks,
Dany
