With gdm3, I was able to remove the last connected users from the list by removing the file '/var/log/ConsoleKit/history'



With lightdm, the last users appears even when :




  • removing /var/log/ConsoleKit/history

  • removing /var/lib/lightdm/.cache/unity-greeter/state



Where does lightdm store this list ?



Edit:
It seems like it's using the content from the last command. Then purging the content of the file /var/log/wtmp is sufficient to remove any previously connected user from the list :



# > /var/log/wtmp


But, after doing this, I have the unwanted side effect that users loging in via lightdm doesn't appears at all in this list.



I must say that I'm in a enterprise network environment using NIS.



Edit2:
Well, it seems that lightdm uses wtmp to display recent network users list, but does not update it. So, lightdm will show a network user only if it logged in in another fashion (ssh, login), like I did on this computer before. cf:





Edit3:
I just added the following line to the file /etc/pam.d/lightdm To force lightdm to store users in wtmp :



session optional        pam_lastlog.so silent

So, to remove last connected network users from the list, just purge the /var/log/wtmp file :



# > /var/log/wtmp


Besides, to make lightdm remember last connected network users, one can add the following line to the file /etc/pam.d/lightdm :



session optional        pam_lastlog.so silent
