Known issues with contact photos via Exchange ActiveSync?

Hi,

are there currently known issues with contact photos in ActiveSync?

My iPhone (Latest iOS: 9.3.1) does not send updated contact photos to horde
(latest stable release 5.2.10). This feature worked already some time ago.

Other changes are send to horde as expected.

Thanks for a first feedback before I start setting up a test environment to
create clean logs.

Regards,

Torben

Efficient handling of denied CalDAV-Requests

Hi,

in our setup, we have a number of users that use CalDAV to access both 
their own calendars and calendars that other users have shared with 
them. Of the shared calendars, of course not all allow write access.

When a CalDAV client tries to write to such a calendar for which it does 
not have permissions, then of course access to it is denied and the 
calendar remains unchanged.  However, there seem to be many clients out 
there that repeat this kind of "unsuccessful" request over and over 
again.  That is, these clients to not get the fact that they will never 
be able to write to the calendar and over time they send a huge amount 
of requests that have to be denied each and every time.  The amount of 
requests grows steadily as CalDAV users keep adding events to calendars 
that they cannot write to -- in the CalDAV client, these events are 
often displayed just fine.

These denied requests already make up a substantial amount of the total 
traffic we see on our Horde servers.  We already tried to block some of 
these requests on the webserver level, but with limited success.  In 
such an event, the clients will receive an HTTP error 403 from Apache 
when trying to write to a certain calendar that they are not supposed to 
write to, but even that does not stop them from retrying the write 
request every couple of seconds.  So having Apache block requests is a 
nice start because it costs less performance than a full-blown Horde PHP 
request with authentication and what else, but fiddling with the Apache 
config to sort out which requests to deny is pretty complicated and 
error prone.

So it looks like we have to deal with the fact that these kinds of

CalDAV/CardDAV with Windows Phone 8.1

Hi,

one of our users is trying to sync his address book and calendars from 
the Horde server to his mobile running Windows Phone 8.1.  Using 
ActiveSync is not an option, so CalDAV/CardDAV is the only way to do it. 
  While Windows Phone does not come with a native client that claims to 
do CalDAV/CardDAV, the client for "iCloud" can be used to achieve this, 
because it uses, in fact, CalDAV/CardDAV and can be configured to use a 
specific server name etc., so it isn't limited to syncing just with iCloud.

Does anyone have experience in using CalDAV/CardDAV with Windows Phone 
and Horde?

In our user's experiments, I can see that proper requests arrive at the 
web server running horde.  The autoconfig seems to work and there are 
requests both for specific address books (e.g. "PROPFIND 
/rpc.php/addressbooks/foo/contacts~2cf02ad3e4c002e0e2c3fba42e0156cc/" 
and "PROPFIND /rpc.php/addressbooks/foo/contacts~favourites/") and 
calendards, but on the client side, nothing is shown.  I don't really 
have a clue what might be wrong.  Any hint would be welcome.

Jens

Nokia Kronolith SyncML problem

Hello,

I tried hard but don't get an old N97 Nokia phone properly synced with Kronolith through SyncML. My
installation is very recent (5.2.11 groupware). There are no issues on the protocol level, the sync
succeeds with no errors it's just that not all entries from the phone are in Kronolith afterwards. From the
logs I get the following:

DEBUG: HORDE Handling <Add> sent from client
DEBUG: HORDE [kronolith] SQL INSERT INTO kronolith_events

These two lines occur repeatedly, actually as many times as there are calendar entries on the phone. But at
one point I see the following:

DEBUG: HORDE Handling <Add> sent from client
DEBUG: HORDE [kronolith] SQL DELETE FROM kronolith_events
DEBUG: HORDE [kronolith] SQL DELETE FROM kronolith_events
DEBUG: HORDE [kronolith] SQL DELETE FROM kronolith_events
DEBUG: HORDE [kronolith] SQL DELETE FROM kronolith_events
.....
DEBUG: HORDE [kronolith] SQL INSERT INTO kronolith_events

As an <Add> request from SyncML is processed many previously added events are deleted before the one to be
added is put into the database. Anyone any hint on what causes this behavior? To sum up, all events to be
synced get into the kronolith_events database but some of them are removed right away during the sync process.

Any help is most welcome.

Daniel

ActiveSync 16 Crowdfunding.

Hi folks,

First of all, a big thank you to all who have contributed to the Tilt  
campaign for this new feature. The campaign has "tilted", meaning the  
minimum goal has been reached and it IS going to happen! I plan on  
getting starting with development on this sometime in December.

There are a few days left on the campaign - it ends on November 25th -  
so there is still some time to help support Horde if any one is  
interested.

Thanks again for everyone's support over the years!

Lookup telephone number with activesync in GAL

Hello,

is anyone aware if it is possible to lookup the telephone number  
calling with activesync in the Global Adress List (GAL). At least  
iPhone does not do this and i would like to know if it is not possible  
because activesync or because of the iPhone preventing it.

Thanks

DAV issue - base uri

Hello,

I want to sync contacts/calendars with android. I tried different 
android apps, until I figured out that already connecting to the 
principals URL is failing.

When I access the principals url 
https://www.XXXXXX.eu/horde/rpc.php/principals/tw/ with a webbrowswer 
manually I get:

<d:error><s:exception>Sabre\DAV\Exception\Forbidden</s:exception><s:message>Requested 
uri (/horde/rpc.php/principals/tw/) is out of base uri 
(https://www.XXXXXX.eu/horde/rpc.php/)</s:message><s:sabredav-version>1.8.10</s:sabredav-version></d:error>

I tried to access the principals url with the demo of horde, there i can 
access the url without error - so I assume the issue is the base uri.

I tried to find a spot in the configuration where to set the base uri - 
but i couldn't.
Does one of you can give me a hint were to set this, please. Or am I on 
a wrong path, and connection issue is something different.

Versions:
Horde Groupware 5.2.2
Kalender (kronolith)

Considering that ActiveSync has no native support for shared  
calendars, or permissions of any kind for that matter, this isn't  
surprising.

Outlook 2013 sync recovery after server down

Dear All,

Recently my Horde server stopped responding (due to no free inodes  
because /tmp/horde_form_* filled up), and it caused most (5 of 6)  
Outlook 2013 clients to loose sync. Outlook does not report any  
errors, but no new emails appear in Outlook, shared & personal  
calendar events disappear or fail to update.

I get various errors in the associated sync logs:
This on a client that was not uploading calendar changes:
ERR: [16751] Could not find state for synckey {xxxxxxxxxx}1.

This on a client that was not showing any calendar events or new emails:
ERR: [3776] Horde_ActiveSync_Collections::getBackendIdForFolderUid  
failed because folder was not found in cache

The only way to resolve the issue is to remove the client from the  
ActiveSync devices page within Horde and then remove and recreate the  
Outlook mail profile on the client.

I'm using Horde_ActiveSync v2.28.1

Every other ActiveSync client (iOS/Android) picked up the sync again  
after the server was fixed, so is it right to assume an Outlook  
setting is to blame?

Many thanks,

Tim
