I managed to get this to work by editing both /etc/pam.d/lightdm and lightdm-autologin and adding:
account requisite pam_time.so after the @include common-account line. Also edited /etc/pam.d/login and uncommented the pam_time.so line. After that, I added a line to /etc/security/time.conf and added a line similar to: login|lightdm*;*;username;!Al1400-1500 to deny login on all ttys and from lightdm for username between 2 and 3 pm. Works with lightdm-gtk-greeter, although strangely instead of saying 'Permissiong denied' it complains about an invalid password. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/880326 Title: lightdm and pam authentication (pam_time) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lightdm/+bug/880326/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
