LightDM - Dec 2012 - Authentication with no passwords

Sort of related to my previous email, I have a problem with logging in
user's where no password is required to log in, such as those in the
nopasswd group.

My code reads (in pseudocode):

greeer.authenticateUser("foo");
onPrompt() {
    greeer.respond(..);
}
onAuthenticationComplete() {
    if (greeter.authenticated) {
        greeter.startSessionSync
    } else {
        showError()
    }
}

In the case where no password is required, the backend goes straight
from authenticateUser to the onAuthenticationComplete callback,
however greeter.authenticated is false so my login fails. How is the
workflow meant to go?

That is the correct workflow - can you check the lightdm.log to confirm
that the authentication did work?
