automatic login for a live user doesn't work

["upiter77@lycos.com" <upiter77@lycos.com>]

hi

I have created a live wheezy hdd:

# lb config --mode debian -d wheezy -b hdd -p lxde

using this autologin script:

# cp  /lib/live/config/010-lightdm /home/live/config/includes.chroot/lib/live/config

but it doesn't work.

It hangs at the login mask with the massage "Debin Live user autologin", but nothing happens. 

greetings
Piotr
