SUMMARY
When testing the plasma login manager (not SDDM), the KCM does not allow the user to apply the plasma settings to the login manager; clicking "apply" in the popup does nothing, probably because it does not try to elevate privileges as the "apply" button in the KCM does.

STEPS TO REPRODUCE
1. Install plasma login manager instead of SDDM
2. Open the KCM and click on "Apply Plasma Settings..."
3. Click "Apply" in the popup

OBSERVED RESULT
Nothing happens, the popup remains opened.

EXPECTED RESULT
The plasma settings should be applied to the login manager and the popup should close.

It's not implemented yet — work exists for this in the work/d_ed/setting_sync branch.
