Include everything I need to reproduce (test code preferably) so I can ensure the UNIX extensions allow this. I tried some other versions of samba (triggered to the fact, that debian lenny now has feature freeze ...). I found that the problem vanished from Samba 3.0.28 on for the testprogram I posted earlier. I had not enough time to test the newer samba versions as user-homes with KDE, but I'll do that soon.
