[kronolith] Adding Remote CalDAV Calendars

[Daniel A. Mayer]

Hi,

I am running Horde Groupware Webmail Edition 5.1.2 with Kronolith 4.1.3
and would like to add a CalDAV calendar hosted on an existing CalDAV
server to Kronolith. The caldav server is a darwin / apple
calendarserver which I've been using for a several years now using
different clients.

Here is what happens when I try to add the calendar: In Horde on the
calendar screen I click on the plus sign next to "Remote Calendars". I
enter the URL to the calendar:
https://<server>:8443/calendars/users/mayer/calendar/ . Horde then asks
me for user name and password. After entering those I receive the
message "The authentication information you specified wasn't accepted.".

On the caldav server I only see the following two requests:
OPTIONS /calendars/users/mayer/calendar/ HTTP/1.0
PROPFIND /calendars/users/mayer/calendar/ HTTP/1.0

The call that is failing on the horde side appears to be
"POST /services/ajax.php/kronolith/getRemoteInfo HTTP/1.1" 200 1274

Am I trying to add the calendar the right way? How does Kronolith
determine whether I am adding a caldav calendar instead of subscribing
to a remote ics file?  If this is the right way of doing it, any
suggestions on how to further debug this?

Thanks,
Daniel
