I'm not aware of any explicit action I took that added my user account to the nopasswdlogin group. I followed these instructions to set up an encrypted system: http://blog.andreas-haerter.com/2011/06/18/ubuntu- full-disk-encryption-lvm-luks. At this step (http://blog.andreas- haerter.com/_media/2011/06/18/full-disk-encryption-lvm-luks_1004_live- session_ubiquity-install-001.png), I chose the "Log in automatically" option. I thought maybe that added me to the nopasswdlogin group, but perhaps some other part of the installation process did it (if so, I don't know what).
It's clearly not the case that only experts who know what they're doing can get themselves into the nopasswdlogin group -- I got in there, and I have no idea how (assuming it wasn't due to selecting the auto-login option on installation). Based on these posts, it appears that other people have also ended up in the nopasswdlogin group without explicitly meaning to: http://askubuntu.com/questions/100010/no-password-asked-at-login-screen-just-start-session-button-with-lightdm http://ubuntuforums.org/showthread.php?p=11566335 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/987330 Title: Insecure login -- not requesting password To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lightdm/+bug/987330/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
