how did you add your user to the nopasswdlogin group? that's not something exposed in the system settings ui in precise nor something any non technical users will run into, those who are technicals enough to play with that should be able to deal with the side effects as well...

This happens whether I get to the login screen via (1) starting up the machine, (2) logging out of a session, or (3) locking the screen and then clicking the "Switch user" button on the locked screen dialog. My entire system is encrypted in a LUKS volume, so I had initially turned automatic login on, as I thought login via password would be unnecessary given that I already have to enter my LUKS password to start up the machine. However, I noticed that when I locked my screen, instead of needing to provide my account password to unlock it, I could simply click "Switch user", and instead of switching to another user (there are no other users on my machine), I could then just click "Login" for my own account, and it would let me in without requesting my password. I thought this might be due to the automatic login setting, so I turned off automatic login. I have confirmed that the "autologin-user=<username>" line in /etc/lightdm/lightdm.conf has changed to "auto-login=". Also, now that automatic login is off, I do get the login screen when I first start up the machine -- yet it still does not require my password. So, I don't think the problem is related to automatic login, as it happens with our without automatic login turned on.
