sddm doesn't work with passwordless accounts or expired passwords

[Aminda Suomalainen]

I wrote a script to add users for family & friends who are here frequently https://github.com/Mikaela/scripts/blob/gh-pages/bash/addusers .

Part of it deletes the password and expired it (`passwd -de $user`) . It appears that SDDM doesn't either understand passwordless accounts or expired passwords as it only gives "login failure". LightDM again tells "you must change your password (root enforced)" and prompts for new password the first time user attempts logging in without password and I believe SDDM should do something similar too.

Reply from upstream:
Issue get's fixed with sddm- version 0.14

Not knowing the micro-release-date yet.

Version 0.14 does not have support for expired passwords.
The feature is planned for Milestone 1.0 (https://github.com/sddm/sddm/issues/472).
Seems no commit activity at sddm site at the moment.

There is a patch available which implements expired password handling.
See pull request https://github.com/sddm/sddm/pull/776 I wrote.
But its not reviewed by the sddm team so far. Not clear if and when it gets merged in the master branch.
The sddm developers seem busy with other work.

Removing Papercuts task as that project is not active.

Reverting status of sddm task to 'Confirmed' as no
explanation was given to change status to 'Incomplete'
