Code=1570 "calendarPath is a required value."

Question

Hi,
  I'm trying to connect the Calendar application on a macos client to the Calendar service on a macos server. On the client I get this error each time:
28/04/14 10:24:11,163 Calendar[44869]: Validation error: Error Domain=NSCocoaErrorDomain Code=1570 "calendarPath is a required value." UserInfo={

    CalManagedObjectType = CalManagedCalDAVCalendar;
    NSLocalizedDescription = "calendarPath is a required value.";
    NSValidationErrorKey = calendarPath;

  I even tried to compile the Calendar server on my mac client as explained at this address:
http://www.ronregev.com/misc/pim_server_tutorial/
  The compiled server works fine, but the Calendar application gives the same error.
The only info I found about this error message is that the Calendar application itself is at fault, and not the server:

Any idea how to make it work?

Answer 1

Never mind, I found the reason to my problem.
And the error message didn't help at all (go figure).
The thing is that my server is connected to ActiveDirectory, and Calendar doesn't support the normal encryption.It works if I disable the password encryption, as explained in this article:

This article is so badly written, it doesn't give an idea of what error message we could expect, or how to make it work with Kerberos. It just tells you not to bother with reading it in the first place.
