[LightDM] Centos7: passwd expired messages

[Robert Ancell]

Hi Johan,

Which greeter are you using with LightDM? The likely cause is the greeter
is showing the expired message then clearing / replacing it so the user
can't actually see it. There is a small risk that LightDM (the daemon)
changed behaviour, but I haven't seen other reports and there's quite
extensive testing in the greeter for a behaviour change like this.

Hope this helps,
--Robert
