zimbra 5.0.18 lightning 0.9 on tb 2.0.0.22 - Modification Failed

[stegbth]

Hi,

i am running Zimbra 5.0.18 on Ubuntu8.04 amd64.
having Thunderbird 2.0.0.22 with Lightning 0.9 clients.

the Urls are connected via https Apache Reverse Proxy.

Read/write works with ics and caldav for the own calendar.

There aren't any write's possible to a shared Calendar, it had fist a space included with %20 which i removed.

Read's are possible on the shared calendar, but when modify i get:
MODIFICATION_FAILED

But the Calendar has write permission, as it works within the Webui.

in Lightning i removed currently the private Calendar as there seems to be an bug within TB, when using HTTPS and more than one Calendar to the same server?

but still no write permission.

any ideas?

No ideas, but maybe a work around.
I have the same symptoms--does the same thing using Thunderbird 3.04b4pre and Lightning 1.0pre (18-Aug-2009 build). Directly connected (no proxy, same subnet).

It works fine, however, with the Zimbra desktop client application. That tells me it can be done, and it probably isnt' Zimbra that 's the problem.

Here's how I got it working (about 5 minutes ago) I deleted all my remote calendars and started over. Further testing on a cow-orker has shown that wasn't needed, I just needed to delete and recreate the shared calendar in Tbird, not my own.

First I added the shared calendar to my web interface (send the share notice, from the OtherPerson's account, and then accept the share from the web gui. Name it something simple like SharedCalendar).


Next, I set it up in Tbird but I didn't use the "proper" path to the shared calendar ics. The normal path--the one that the sharing person's Zimbra interface says to use for the share--would be something like

 https://mail.mydomain.com/home/OtherPerson@mydomain.com/Calendar

If I put that into Thunderbird's Location field, I'm able to read but not write.
Instead, I use this in the location:

 https://mail.mydomain.com/home/MyName@mydomain.com/SharedCalendar

This lets me modify the shared calendar. Further I put my private calendar back into Thunderbird, and I can still use it. The key seems to be having the shared calendars all set up in my account via web gui, and then using MyName@mydomain in the path instead of the actual SomeOneElse@mydomain when setting it up in Thunderbird

After upgrade from 5.0.15 to 5.0.18 I can no longer dismiss appointment alarms nor add new appointments. Lightning errors saying calendar can not write to calendar.

Error Number: MODIFICATION_FAILED

I have deleted my calendars and recreated only my own.

The link I was using changed.

Before change I was using the following.

https://zimbra8.wiu.edu/home/ke-mccormick/Calendar

After change Zimbra tells me to use the following.

https://zimbra8.wiu.edu/home/ke-mccormick@wiu.edu/Calendar

This looks to be a Zimbra bug to me.

I am using Thunderbird 2.0.0.23 and Lightning 0.9 build 2008091719

Created bug report.

Bug 40946; Lightning can not write to calendar.

[stegbth]

Hi all,

i doing some search again and found an error on my configuration.

there does exist a apache reverse-proxy in-front of the zimbra.

there was only forwarded
/zimbra
/home
/service

-> /dav was missing

now i am able to add a caldav calendar against zimbra 5.0.18 with lightning 0.9 and thunderbird 2.0.0.23



but there is a "new" issue, i currently do not know.

when having the caldav calendar aktivated and i restart thunderbird. tb wont be able to open the imap-folder's and zindus wont be able to authenticate.
this problem happens also, when deaktivating zindus.

the "solution" is:
deactivate the calendar (in options of lightning-calendar, not the marker before the calendar-name!), restart thunderbird, then zindus and imap works fine.

now activate caldav. it takes a while until all my calender items are loaded.


will try to setup the caldav directly to zimbra instead of the apache reverse-Proxy and update this thread afterwards.

greetings
thomas

new Information:

this seems to be a bug of Thunderbird2 and SSL

https://bugzilla.mozilla.org/show_bug.cgi?id=390036

with a short test with TB3b4 and Lightning1pre it didn't happen at a short test about two hour's. Went backup to tb2 as Zindus doesn't work on TB3b4
