When I boot the raspberry and try to login via ssh with username:pi and password:raspberry I only get the "access denied" message as if the password were not correct. I found out that the password is always list after reboot so I have to set the password for pi manually everytime to be able to use ssh login.
I have used chage to check if the password expiration is disabled and it is. Does anyone maybe know why the raspberry always deletes the password for the user pi or at which point the raspberry should set the password automatically?
