10.4: Resolve an iCal publishing problem Apps
Tiger only hintAfter replacing my hard drive and re-installing Tiger on my machine, I discovered that iCal was no longer able to publish my calendars to my web server -- I have a Linux web server running Apache and WebDAV for a certain directory tree, on an SSL-enabled web site.

The error message was so helpful:
Publish failed for calendar "blah"
Unexpected secure name resolution error (code -9812). The server name may be incorrect.
The log file on the web server didn't show any successful connection. However, a little bit of work with Ethereal (a free packet sniffer) revealed that iCal was indeed connecting to the server, but the SSL negotiations were failing.

The fix was to run Safari (which I don't normally do, I prefer Firefox) and visit the SSL web site where iCal is trying to publish the calendar. When Safari complains about the SSL certificate, I turned on the "Always trust this certificate" checkbox, and clicked "Continue." It asked me to authenticate, and then added the certificate to the "X509 Anchors" keychain.

At this point, I had to quit iCal entirely, but when I started iCal again, it was able to publish correctly.

Bummer -- I tried this (even before reading the hint since it seemed the right thing to do) and I still get the error. I can visit the url now in Safari without any warnings using ssl, but I'm getting that same error in iCal still. Any ideas?

If you follow the directions exactly, it works (for me with 10.4):
- quit everything
- start safari, navigate to site, check "always trust cert", click "continue"
- start ical, do your thing.

I tried many other permutations, which didn't work (I'm guessing the apps cache their keychain queries).

Just encountered this on 10.5 when a secure certificate was changed on our Zimbra server, and this solution worked for me. Thanks for posting -- great tip!

WOW! This really saved me too! And here it is 10.5.6 of April 2009! Thanks! All 5 of 6 machines could get to our hosted iCal, but my laptop could not and we couldn't find a certificate anywhere. Using Safari and the URL really worked and fixed EVERYTHING!


Safari was able to do what iCal just could not!

If using a secure connection make sure upper/lower case match in the iCal server config (Host Name) and client config (Account URL).
