kdmctl login stopped working

Hi,

i used to login a specific user via shell script and kdmctl. I did it like this: “kdmctl login :0 now username pwd”.
I upgraded my suse install to 12.1 a while ago and it still worked. But since a few weeks now it doesnt work anymore. Kdmctl returns “nosys unknown command” and nothing happens.
Im not sure if i changed something, but i think i did not. Im using yasts autoupdate to keep my system up to date. Maybe some update introduced this problem?
I dont know what to do. What could be the problem? Can you help me, please?

Regards
pepe
