[FreeNX-kNX] silly question

[Chris Fanning]

Hello,

I'm using nxclients on kiosk pc's. All users connect to the same
server so I have a session.nxs defined too.

When the PC boots, .nx/nxclient.cfg and .nx/session.nxs are copied
from /etc/skel to the kiosk system user's home.

When X gets loaded and the nxclient pops up, the system user's name is
preloaded into the nxclient dialog.
In session.nx I have
<option key="User" value="" />

I would really like an empty Login:

How should I do it?

Thanks.
Chris.
