LightDM login loop

Hi,

I've recently installed LightDM on my desktop with KDE (before I've used KDM as login manager) and webkit greeter.
I can see the LigthDM greeter screen but when i try to login i get redirected to the greeter screen.

When I execute

lightdm --test-mode --debug

and I enter my username and password this is my output:

This is my /etc/lightdm/lightdm.conf:

[LightDM]
minimum-vt=1
run-directory=/run/lightdm

[SeatDefaults]
allow-guest=true
autologin-guest=false
#autologin-user=
greeter-session=./lightdm-webkit-greeter
pam-service=lightdm-autologin
session-wrapper=/etc/lightdm/Xsession
user-session=kde-plasma

[VNCServer]
enabled=false

[XDMCPServer]
enabled=false

What is wrong?

Thank you.
