[horde] Horde/Kronolith/Dav & Shared Calendars

[Anthony Messina]

Hello, firstly, I would like to thank you for Horde.  I am in the  
process of migrating from an EGroupware-based groupware solution to  
Horde 5.1.5 with the groupware components.  So far, and with some  
hefty Googling, I have almost everything working as expected.

1. Users, authentication, and pre-authentication hooks (id, from_addr,  
fullname) via an external FreeIPA (LDAP) server.
2. Groups stored in Horde (SQL)
3. Turba with shared addressbooks, etc.
4. Everything except...

I have run across a snag though in that I cannot seem to get "shared"  
calendars to become available via the CalDAV interface.  Again, with  
some extensive Googling, I was able to reach  
http://bugs.horde.org/ticket/12380 and  
https://github.com/horde/horde/commit/83c961a5bbd28a41f9d897ae827bee00b628d59b  
which lead me to believe that there is a workaround and that my users  
*should* be able to see each others' calendars via CalDAV, so long as  
they have been shared in Horde/Kronolith.

As "auser" I have created a calendar which I edit permissions and  
allow "mygroup" (which contains "auser" and buser" members) to "read  
and edit the events."

Using either Kontact/Korganizer/Akonadi or CalDav-sync (Android), as  
"buser", when logging into http://example.com/horde/rpc/ I am only  
able to retrieve my own "buser" calendar and task list.

When I browse the DAV interface as "buser," using the subscription URL  
https://example.com/horde/rpc/calendars/buser/calendar:qmXKW9x9hZFr7VvyL1Wej1V/ I get the  
error:

<d:error xmlns:d="DAV:" xmlns:s="http://sabredav.org/ns">
<s:exception>Sabre\DAVACL\Exception\NeedPrivileges</s:exception>
<s:message>
User did not have the required privileges ({DAV:}read) for path  
"calendars/auser/calendar:qmXKW9x9hZFr7VvyL1Wej1V"
</s:message>
<s:sabredav-version>1.8.7</s:sabredav-version>
<d:need-privileges>
<d:resource>
<d:href>
/horde/rpc/calendars/auser/calendar:aOtncQmkqMfKx2D1R6ZlwA7
</d:href>
<d:privilege>
<d:read/>
</d:privilege>
</d:resource>
</d:need-privileges>
</d:error>

Please let me know if I am misunderstanding the commit message,  
indicating to me that I *should* be able to see others' shared  
calendars via CalDAV, if there is some other permission or  
configuration issue that I might be missing, or any debugging  
information that might be helpful.

Thanks in advance for your help.
