Title:
  limits.conf not applied

Bug description:
  Since upgraded to 16.10 Yakkety, modifications in
  /etc/security/limits.conf are not taken into consideration when
  logging in the graphical interface.

  
  /etc/security/limits.conf:
  @audio   -  rtprio     99
  @audio   -  memlock    unlimited

  I tried the same settings in /etc/security/limits.d/audio.conf, to the
  same results.

  
  After logging in Unity, opening a console, the limits are not set:
  blablack at ideaon:~$ ulimit -l -r
  max locked memory       (kbytes, -l) 64
  real-time priority              (-r) 0

  
  Reloging to my user via bash DOES apply the limits:
  blablack at ideaon:~$ ulimit -l -r
  max locked memory       (kbytes, -l) 64
  real-time priority              (-r) 0
  blablack at ideaon:~$ su blablack
  Password: 
  blablack at ideaon:~$ ulimit -l -r
  max locked memory       (kbytes, -l) unlimited
  real-time priority              (-r) 95

  
  Switching to a console (ctrl+alt+f1) and logging in would apply the limits as well.



  The exact same setup used to work fine on Xenial 16.04 before upgrade.

  
  If you need any more information, please let me know.
