[CentOS] CentOS 7 and vino

I am trying to get vino going on CentOS 7.1

I run this command:
 gsettings set org.gnome.Vino require-encryption false

Then this one:
 gsettings list-recursively org.gnome.Vino
org.gnome.Vino notify-on-connect true
org.gnome.Vino alternative-port uint16 5900
org.gnome.Vino disable-background false
org.gnome.Vino use-alternative-port false
org.gnome.Vino icon-visibility 'client'
org.gnome.Vino use-upnp false
org.gnome.Vino view-only true
org.gnome.Vino enabled true
org.gnome.Vino prompt-enabled false
org.gnome.Vino disable-xdamage false
org.gnome.Vino authentication-methods ['none']
org.gnome.Vino network-interface ''
org.gnome.Vino require-encryption true
org.gnome.Vino mailto ''
org.gnome.Vino lock-screen-on-disconnect false
org.gnome.Vino vnc-password 'keyring'

The require-encryption does not change.

Any reason why its not changing?

Thanks,

Jerry
