zimbra 5.0.18 lightning 0.9 on tb 18.104.22.168 - Modification Failed
i am running Zimbra 5.0.18 on Ubuntu8.04 amd64.
having Thunderbird 22.214.171.124 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:
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.
solved partially - maybe a Lightning Bug?
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
-> /dav was missing
now i am able to add a caldav calendar against zimbra 5.0.18 with lightning 0.9 and thunderbird 126.96.36.199
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.
