Hi,
I also tried the certificates with Apache - it works. However, when starting Apache, I was prompted for caldav-server.key's password. Maybe that is causing problems for twisted? If so, how could I create a passwordless key, if possible?
Yes, I think you have to strip the password from the key. I had to do it for older versions, and if that has changed let me know. I did some attempt to add http://docs.python.org/2/library/getpass.html to read the passphrase for the key, but it had some problems, probably because I was not sure about what the different processes did at the time, and how they communicated. Some day I might try again. This is how to strip it : openssl rsa -in filename.key -out filename.key.nopass It is not optimal, and it makes me cringe everytime an application makes me do this.. Exim does it to. Luckilly I am not running some important calendarserver so I can live with it for now. /Fred
