Believe me or don´t believe me, today I tried from my HomeOffice with a 
Laptop with the same KDE version and I think the same SuSE version and 
it worked.
Popup, authentification, deleting, everything. The same server config as 
yesterday.

As if nothing had happened before....
I will try to check the difference between my installation here and in 
my office.

In the moment thanks to Kurt and Michael.

Greetings, Helge
