I know this is an old thread, however this has just happened to me on ubuntu 14.04, I had not made any change to /etc/shadow myself, and this is a fairly clean/new install. I came across this bug directed from here http://askubuntu.com/questions/128785/lock-screen-password-incorrect so this seems to be a common occurrence - is it worth reopening this and investigating why the permissions on /etc/shadow keep changing? -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-screensaver in Ubuntu. https://bugs.launchpad.net/bugs/600631 Title: Password does not unlock screen To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-screensaver/+bug/600631/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs

Ok, through the exploiting myself like Jon Oberheide /etc/shadow got wrong rights. After resetting the rights of /etc/shadow, there are no problems any more.

[Bug 600631] Re: Password does not unlock screen
What's ls -l /etc/shadow look like? /etc/shadow should be 640, owner root, and group shadow. I only ask because I ran into the same issue after exploiting myself with the recent pam_motd vulnerability. My PoC (http://twitter.com/jonoberheide/status/18009527979) changed the ownership of /etc/shadow and upon changing it back (I think I did chown root:root instead of root:shadow), I had the same issue of not being able to log in via the screensaver and the same check pass; user unknown error message (unix_chkpwd can't read the file if its not shadow group readable). I would blame it on the recent vulnerability...except that your initial bug report pre-dated the vulnerability announcement. :-) -- Password does not unlock screen https://bugs.launchpad.net/bugs/600631 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-screensaver in ubuntu. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
[Bug 600631] Re: Password does not unlock screen
The owner was root:root, must have changed it by mistake when I put back password from previous install of Ubuntu. Doing chown root:shadow /etc/shadow and chmod u=r,g=r /etc/shadow fixed the problem. Thanks for the tip. Have to be more careful next time I modify shadow and password files. So this is not a bug about screensaver not accepting valid password, but a bug raport of the screensaver not showing warning message about wrong permissions in the /etc/shadow file. -- Password does not unlock screen https://bugs.launchpad.net/bugs/600631 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-screensaver in ubuntu. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs

All users accounts I have tried this with have the same problem. I created a new account just now, even for that user screensaver did not accept the password. User could log back in to the locked session by switch user and login from graphical login screen.

I forgot to say, that this is a clean install of 10.04. I did, however, have the /home on another partition, so users home directories and perhaps screensaver settings are from 8.04, which I ran on this computer before installing 10.04. -- Password does not unlock screen https://bugs.launchpad.net/bugs/600631 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-screensaver in ubuntu. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
