Can’t view shared calendars via WebDAV in 8.7.1

Summary: Certain WebDAV responses for shared calendars in ZCS 8.7.1 may not be compliant and thus causing shared calendars not to display when accessed via WebDAV clients.

Issue: Since from ZCS 8.6.0 to ZCS 8.7.1 DAVdroid (1.3.4.1-ose) users are unable to see calendars shared to them. This affects RW and RO calendar shares equally.

Note: Calendar sharing works fine in the web client.

Prior Version: In 8.6.0 DAVdroid was able to view shared calendars via DAV, in 8.7.1.

Forum Post where issue was described by DAVdroid developer as:
When a WebDAV client like DAVdroid requests information for /dav/mthoben%40mpipz.mpg.de/SUSAN%20Calendar, but the server sends information about /dav/shares_susan%40mpipz.mpg.de/Calendar/33493472-4a26-4398-a074-d382b9b36a18.ics, there is a problem. This is not how WebDAV works – there is no way for a client to detect that the given information is related to the requested resource. This is a server bug, please report it to Zimbra.

I just found that while the shared calendars can't be viewed and thus not edited.

Where read/write access to the shared calendar applies, calendar events can be created in the shared calendar on the phone and are shown in the Zimbra web based calendar after sync completes.

How can I help volunteer my time to assist with this bug?

I'm able to provide logs from a specific scenario to help validate it.

I'm just not sure who to offer this to as I'm not sure how to get in contact with this bug's primary contact person.

It's really distressing to see how dead this forum is, even when users are actually trying to help with rather complex and annoying issues.

This sounds like it may have the same root cause as https://bugzilla.zimbra.com/show_bug.cgi?id=106438 which was fixed in 8.7.7 - see https://wiki.zimbra.com/wiki/Zimbra_Releases/8.7.7
