LightDM - Dec 2017 - Centos7: passwd expired messages

Hello All, 

first of all: thanks for creating lightdm, that we 've been using for ages. 

We run some 200 Centos7/Mate laptops, since last year they authenticate against
freeipa.
Lightdm/Mate are installed using epel repo. 
On Centos7.3/Lightdm 1.10.6-4.el7 things were al right, when a password expired,
users would get the passwd expired field, the "new password" field en
warnings if the made a mistake.
Since upgrading to Centos7.4/Lightdm 1.25.0-1.el7 things go terribly wrong.
Users very often get no warning if a password expired, just an authentication
failure.
Or they get no message at all. 
If at that point you got to tty....and log in you do get the warnings on the
command line.
The log files /var/log/secure also give clear password expired messages, only
the user sees nothing.

I don't know too many people who run Centos7 on the laptop let alone
authenticate against freeipa, so I have no idea if this is a general problem.

Many thanks for any help. 

Greetings, J.

Hello All,

sorry to bother you with the same problem as described above.

I posted on the Freeipa mailing list but still have no solution.
I ran various tests and the only thing that seems to work is replace lightdm
with gdm, then passwd expire messages and other messages re-appear.
The only thing still to test is downgrade lightdm.

Any help would be greatly appreciated.

greetings, J.
