Comment 1 Ãlo Parri 2014-12-31 10:13:47 CET 
I have Plasma 5 self built with kdesrc-build and had unlocking problems too.

Solution for me was:

#pam permissions, kcheckpass needs file named 'kde'
ln -s /etc/pam.d/kcheckpass /etc/pam.d/kde

#suid root for kcheckpass
chmod  +u /opt/kf5/lib64/libexec/kcheckpass

This is probably not done with Mageia packages.
With Mageia packages the last line should be
chmod  +u /usr/libexec/kcheckpass

Thanks for the info, Ãlo!
In my case I had neither kcheckpass nor kde files in /etc/pam.d

Found a upstream bug about that: https://bugs.kde.org/show_bug.cgi?id=337470 , however its status is unconfirmed.

But creating a /etc/pam.d/kde file with the content suggested there helped and I can unlock the screen now.

However the lock screen still states incorrecty that Caps Lock is on. Fortunately it does not affect the unlocking process...

please test new rpms for the unlocking issue
Comment 4 Jüri Ivask 2015-01-05 08:48:07 CET 
Updated to plasma-workspace-5.1.2-6.mga5
Unfortunately this made it again impossible to unlock the screen.
Running /usr/libexec/kcheckpass just hangs.
Renamed new kde file in /etc/pam.d to kde.old and created again a new one according to https://bugs.kde.org/show_bug.cgi?id=337470 and the
/usr/libexec/kcheckpass started to ask for password and accepted that and also screen unlocking worked again (with that incorrect Caps Lock statement)

Fixed typo introduced in r808414. Reopen if still broken.
