Connect to XDMCP clients on address requests come from if available

This bug was fixed in the package lightdm - 1.15.1-0ubuntu1

---------------
lightdm (1.15.1-0ubuntu1) wily; urgency=medium

  * New upstream release:
    - Fix default X server command set to XMir in 1.15.0.
    - Internally merge the [SeatDefaults] and [Seat:*] sections together. The
      previous method meant configuration snippets using a mix of old and new
      naming would not correctly override eachother.
    - Use IP address of XDMCP requests to contact X server if available.
      (LP: #1481561)
    - Add an option for XDMCP and VNC servers to only listen on one address.
      (LP: #1390808)
    - Fix configuration file warnings so they go to the log, not stderr.
    - Warn if deprecated options logind-load-seats or xdg-seat are in
      configuration. (LP: #1468057)
    - Improve IP addresses in XDMCP log messages.
    - Fix typo in dm-tool man page. (LP: #1470587)
