Account lightdm has expired - the user manager service is failed

Hi!

I have recently installed Arch Linux on my desktop PC, and I have realized that when I list all systemd services with systemctl --type=service, I get a failed service called user@974.service.

$ systemctl status user@974.service

● user@974.service - User Manager for UID 974

I have an other Arch install on a bootable USB stick, that doesn't produce this error. Why on earth is the light-dm user expired?
It doesn't cause any problems in the user experience that I have noticed, but the system has only been installed last weekend. I am kind of stuck with my searching on google, most of the stuff I find is related to the lightdm.service, but in my case, that's up and running with no problem.

Most likely it's the same issue as here.

Thanks for the fast reply!
I have submitted the issue to the lightdm github page (https://github.com/canonical/lightdm/issues/90), should I open a bug report on Arch Linux bug tracker, too?

lightdm.pam and lightdm-autologin.pam are provided by arch not from upstream lightdm so I do not believe it is an upstream lightdm issue.
It could be considered a packaging issue (it should also affect sddm and lxdm).
On your system you can disable password expiry for the lightdm user with:

chage -E -1 ldm

Thanks!

This definitely solved the issue with the login manager for lightdm. I'm still wondering though, why does the lightdm account need a this, especially considering the fact that my system worked without any noticeable problem when it couldn't run.
