Comment 3 for bug 41341

Some more information:

First, either my "aguest" account was broken or it got corrupted by the kdesu-experiments, anyways, now I can't even log in normally from kdm, but that's a different story.
Now I set up two new and clean users "test" and "test2", let's call the admin-user "user1".

Now, "kdesu -u test2 -c kwrite"
1) when started by user1 produces no more error messages, but still asks for user1's password. The kdesu man page says:"It allows you to run programs as another user by entering their password." This means test2's password, doesn't it?
2) when started by test, kdesu asks for a password, but always says "Incorrect password; please try again." no matter what password (user1's, test's, test2's) is entered.

By the way, su works fine.
Hope this makes it clearer now.. I tried to eliminate all influences from my personalized setup :)

kind regards,
raph
