[horde] Caldav / Carddav and IOS

[Henning]

Hi all,

After bypassing this bug http://bugs.horde.org/ticket/12305 by using the
Imap server directly as an authentication backend instead of IMP I can now
use the DAV Server again. I can get individual calendars and adress books to
sync with Caldav compatible Applications like "em Client". The principals
directory doesn´t work with any program I have tested so far.

My main problem is that I can´t get IOS to work at all. I always get an
"Unable to connect via SSL" no matter what I try (principals, single Caldav
Calender, Carddav). SSL works with the DAV Links with other Clients and with
browsers, so I suspect that it is not really the culprit. Apache, PHP and
Horde show no errors. Apache shows an "x.x.x.x - - [11/Jun/2013:23:50:10
+0200] "PROPFIND /webmail/rpc/calendars/user/calendar%xxxxxxxxxxxxxx/
HTTP/1.1" 405 592 "-" "iOS/6.1.3 (10B329) Preferences/1.0" and thats it.

Has anyone succesfully tested Caldav with iOS so far or is it just my
configuration somewhere?

Regards

Henning
