[horde] CalDAV rejects authentication on shared calendars

[Stephan Kleber]

Hi,

since yesterdays updates calendars Horde-internally shared by other
people to me cannot be retrieved (or updated) by CalDAV. Manually
browsing to the calendar URL gives (after! authentication for user "blubb"):

<?xml version="1.0" encoding="utf-8"?>
<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/stephan at admin.nabira.de/calendar:35f58ec1d0e74db1537a825da577f3c1"</s:message>
  <s:sabredav-version>1.8.4</s:sabredav-version>
  <d:need-privileges>
    <d:resource>

<d:href>/horde/rpc.php/calendars/stephan at admin.nabira.de/calendar:35f58ec1d0e74db1537a825da577f3c1</d:href>
      <d:privilege>
        <d:read/>
      </d:privilege>
    </d:resource>
  </d:need-privileges>
</d:error>

calendars own by blubb can be accessed normally (on first glance) via
CalDAV.


Browsing the caldav interface a bit I found

horde/rpc.php/kronolith/stephan%40admin.nabira.de/35f58ec1d0e74db1537a825da577f3c1

which does not work either.

Ideas?
