[dev] Calendar.app fails to load Kronolith Calendar

[Michael Wisniewski]

Hi!

I'm running on...

Calendar (kronolith) 4.1.0-git

and trying to configure Calendar.app on OSX to use the "CalDAV  
Subscription URL".  When configuring the app, I choose "CalDav" as the  
Account Type, and the "Server Address" is...

https://<foo>/webmail/rpc.php/calendars/wisniewski/calendar:Ii<something>2/

When it is "Verifying Account", I get an error that displays "Server  
with Secure Communication Unavailable", and this is in my apache  
logs....

19<ip>9 - wisniewski [14/May/2013:11:32:30 -0500] "PROPFIND  
/webmail/rpc.php/calendars/wisniewski/calendar%3A<something>2/  
HTTP/1.1" 207 1387 "-" "Mac OS X/10.8.3 (12D78) Calendar/1648"

When I turned the Horde debug logs on, nothing in there shows anything  
as failed, or anything that would make it sound like it's bad.

Does anybody else out there run OSX and have their calendar sync with  
CalDav to Horde?  Are you experiencing issues too?

Thanks!
