Problem with accessible login in Karmic

[Hammer Attila]

Dear List!

I read the gdm help documentation, and after finished, I try setting the 
accessible login feature with Karmic.
I setted the /desktop/gnome/applications/at/screen_reader_enabled gconf 
key, but Orca does'nt automaticaly start when login screen is displayed.
Anybody known what the correct method to setting accessible login 
feature with new gdm in Karmic, or this feature now does'nt work?
