Hi Dan,

      core: ignore authorization for sleep/wake requests (but restrict to root) (rh #638640)
      
      Everyone uses pm-utils still for sleep/wake support, and that's
      traditionally how NM was put to sleep and woken up.  But pm-utils
      uses dbus-send without --print-reply so dbus-send quits immediately
      after sending the message.  That doesn't give NM enough time to
      get the senders UID and thus validate the request, so the request
      gets denied, and sometimes NM stays asleep after the machine is
      woken up.
      
      Instead, don't get the sender's UID and try to authorize it, but
      just let the request go through.  Rely on D-Bus permissions to
      make sure that only root can call sleep/wake methods.

Why not have NM ship the pm-utils sleep hook instead of having to
work around what they ship?  Last I checked, NM is the only app
for which upstream pm-utils ships a sleep hook, and Victor (the
lead dev there) was hoping to have apps ship their own so that
he didn't have to maintain stuff that he may not be familiar with.
