there is nothing in /etc/profile and the user oweinmann has no .bashrc. The
problem seems to be related to nscd. When nscd is turned on i can login and
issue commands and I don't get kicked out of the ssh login. There is no idle
session timeout set. If there was I would get kicked out when nscd is turned
on as well. Only when logged in as an AD user I get kicked out...
