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.

Title:
  lightdm and pam authentication (pam_time)

Status in “lightdm” package in Ubuntu:
  New

Bug description:
  in previos version of With Ubuntu Linux, it is possible to assign to
  your computer time restrictions, to prevent the connection of one or
  more users to your system. With the time restrictions, you can, for
  example, limit access to the computer for your children (a kind of
  parental control, in short), or even protect the connection to your
  server during certain hours.

  I use PAM (Pluggable Authentication Modules). It allows you to control
  user authentication when they connect. Then, we will use the security
  configuration files to define logon hours allowed. Enable Restrictions
  hours via the PAM Module

  First of all, first go to the /etc/pam.d/, where is all configurable
  services: This is available by default in the kernel of linux...

  If we want to block the connection to the computer, we will have to
  change the gdm service. Edit the file so gdm and add this line of code
  (at the end of file):

  account required pam_time.so

  GDM is the login screen distributions in Ubuntu but in 11.10 this
  change to Lighdm and i can't get this work again....

  I tested this parameter in the follow files :

  /etc/pam.d/lightdm and also /etc/pamd./lightdm-autologin

  without success .....

  I also notice that that som pam parameters change like

  auth, session

  How i can get this solution available again ??????
