It's me again

Currently I am the only one running on a 10.6 developer seed. But as Mac OS X 10.6 will be released in Q4 2009, this should be a pretty much final version!

As reported in the post above, the Zimbra iSync 32bit plugin is not compatible with the 10.6 64bit system.
After thinking this only affects my addressbook, I had to learn this goes much further I thought:

Looks like there is trouble with CalDAV in iCal also!

1. After I updated from 10.5.7 to 10.6 iCal seemed to work as I did setup my Zimbra calendar as CalDAV account earlier (not using the iSync plugin)
2. Read/refresh did work fine for Zimbra CalDAV
3. Zimbra CalDAV Calendar entries could not be modified nor can new entries be created
4. After deleting the CalDAV account which was setup under 10.5, I was first not able to create it again using my Zimbra credentials
5. It seems you have to be VERY patient as iCal seems to do some tests to check the type and functionality of the account provided!
6. I am still not able to create/edit entries getting an error message "Only the calendar administrator and any delegates with permission can make changes to read-only calendars..."

One issue might be that we are using a selfsigned SSL certificate, the other issue might be that Apple again did some specific CalDAV implementations for their own server

Hopefully any other Apple related sysadmins will read this and help on working out a solution for future 10.6 users!

The following may help the Zimbra guys to verify their plugin:
