SDDM doesn't support `passwd -de`

[Mikaela]

As I don't want to know passwords of my family members, I reset them with passwd -de after reinstalling OS or they have forgotten them.

With LightDM this prompts a message that root has enforced the user to change password and asks for new password, confirmation for it and then the user can login using that password.

SDDM only says Login failed.

From the passwd flags, d removes the current password and e marks the password as expired requiring new one during next login.

• OS: Antergos
• SDDM version: 0.11.0-3

Our PAM library should have everything to detect this situation. Most likely a missing feature on the themes and/or propagation of the PAM thingy. Definitely something we want to have.

Sorry, accidental close.

Workaround: get the user to ctrl+alt+F\<n> to get a terminal login prompt and do the password change there, then logout (exit) in that terminal and ctrl-alt-F\<n> back to the sddm for a login to KDE. Should work everywhere but tested on Alma Linux 8.6.

We had this problem and switch to gdm, as a temp workaround (ugly, I know, because that has gtk dependencies, but works) until this is resolved. Lightdm did not work for us, system didn't appear to boot anymore, we could not (quickly) figure out why.

update: lightdm works too, we had invalid lines in /etc/environment.
