Kubuntu's Lightdm doesn't respects nopasswdlogin group

[Jörn Schönyan]

Hello everyone, I want to be able to log into my account without typing a password, mainly because I have an Optimus notebook and use the new nvidia-prime feature from Trusty which I've packaged for Saucy and have to log out and in to change the active graphic card. So I created the group nopasswdlogin and set my user account to be in this group:

joern@joern-notebook:~$ groups
joern adm cdrom sudo dip plugdev lpadmin nopasswdlogin sambashare vboxusers libvirtd

This works, at least, in Xubuntu. Kubuntu doesn't respects this and I have to type in my password. Changing Lightdm's greeter to lightdm-gtk-greeter also doesn't works.

Hi there!

Thanks for reporting this bug! Your bug seems to be a problem with the KDE program itself, and not with our KDE packages. While we appreciate your issue, it would be better if it was tracked at https://bugs.kde.org, so that the KDE developers can deal with this speedily and have direct communication with you as the reporter for more effective debugging.

Thanks!
