Kiosk Mode and Single Application Mode

Hello to everyone

Few wweks ago i tried to install a RedHat 7 Workstation as Kiosk mode following the guide:

https://access.redhat.com/solutions/4243461

But it didn't worked at all, i just copied the configuration file but i was unable to login.

Actually my goal is to set up a workstation where only one application can run so i try also this guide:

https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/html-single/desktop_migration_and_administration_guide/index#single-application-ode

That i think RHEL has modified lately and it works, but instead to run gedit i need to run google-earth

Can you tell me what i have to modify?

i've tried to modify the file /usr/bin/redhat-kiosk

Changing

    gedit ~/.local/bin/redhat-kiosk

With

/user/bin/google-earth-pro

like below:

#!/bin/sh

if [ ! -e ~/.local/bin/redhat-kiosk ]; then
    mkdir -p ~/.local/bin ~/.config
    cat > ~/.local/bin/redhat-kiosk 
#!/bin/sh

while true; do
    /user/bin/google-earth-pro
done

    chmod +x ~/.local/bin/redhat-kiosk
    touch ~/.config/gnome-initial-setup-done
fi

exec ~/.local/bin/redhat-kiosk "$@"
#

but it didn't worked, what i have to change to make it work?

Thanks in Advance

A.
