how to add a remote login to XDMCP Chooser in the login window

[Abdelkader Belahcene <abelahcene@gmail.com>]

Hi,

I want to log in a remote server using xdmcp from my local machine, unfortunately there is no chooser in my local login (I use lightdm).
How to add a remote connexion to the list in local login window?
I remember 8 or 9 years ago, in the login window (may be with  xdm) there was a remote login in the list.
 
thank
