Gutsy thin client autologin

Yes, I can login with this username/password manually when the LDM_* lines
are commented out. I built the image with the ltsp-build-client command.
Apart from changing the IP address and adding users, it's a standard
Edubuntu 7.10 installation.

I'm assuming I don't need to do rebuild the image each time I make a change
to lts.conf in the tftproot?

At the moment, the user only exists in /etc/passwd, not
/opt/ltsp/i386/etc/passwd. Do I need to make sure the user exists in both
files? If so, is there a correct way to do this? (Sorry if these are basic
questions, I've only recently started playing around with ltsp!)

Can you login manually with this account  (user/mypassword) ?

Have you build special ltsp environnement (ex: kiosk ) ? or update image ?
