Guest login support in lightdm webkit greeter

гm having trouble getting the guest login option to work in the Вебкит Лигтдм greeter, which is в shame эксперт it's otherwise в superb tool for developing custom greeters.

Looking through the source on both LightDM and the Webkit greeter it seems that this feature might not be implemented, but гm не expert. Ты существуешь anyone else tried this?
