We're having recurring problems with users not being able to edit events they should have access to in linked calendars they have write access to when using CalDAV and iCal 3.0.5 and 5.0.10. We see a large number of situations like the one I've listed below. This type of issue occurs across a number of different types of events.
In this example,
user10@calendar.exmpl.com has shared their calendar with
user11@calendar.exmpl.com giving user11 "Manager" privileges.
user11 uses iCal 3.0.5, and has user10's calendar linked and named user10-Calendar.
user10 has created the actual event, which appears in user10-Calendar in user11's iCal as a shared calendar.

And user11 sees on-screen the error:
Access to "Portfolio Review" in "user10-Calendar" in account "calendar.exmpl.com" is not permitted.
Ther server responded: "HTTP/1.1 403 Forbidden" to operation CalDAVWriteEntityQueueableOperation.
Go Offline / Revert to Server
The user *can* edit the event successfully in the web interface. I've submitted this as bug 33429, but was hoping that someone in the forums may also be able to help.
Thanks,
