Request for Feedback: New CalDAV and CardDAV implementation for Kopano

@Fux said in Request for Feedback: New CalDAV and CardDAV implementation for Kopano:

When I try to access contacts via kdav I get the following error at a few contacts - the others work:

<?xml version="1.0" encoding="utf-8"?>

Does anyone know where to search for a solution?

I have this issue. Has anyone submitted example contacts to demonstrate the problem? It currently means I can’t sync with Apple Contacts. The line where the problem is seems to be the UID line.

Hi all
im stuck by a depreaching warning…using Ubuntu 18.04.3

i do the following:

Install sabre-dav:

sudo apt-get install php-sabre-dav

create working kdav folder:

mkdir /var/www/kdav
cd /var/www/kdav

wget https://github.com/Kopano-dev/kdav/archive/v0.9.0.tar.gz
tar xfvz v0.9.0.tar.gz
mv kdav-0.9.0/* /var/www/kdav
rm -r kdav-0.9.0
rm v0.9.0.tar.gz

php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"
php -r "if (hash_file('sha384', 'composer-setup.php') === 'a5c698ffe4b8e849a443b120cd5ba38043260d5c4023dbf93e1558871f1f07f58274fc6f4c93bcfd858c6bd0775cd8d1') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;"
php composer-setup.php
php -r "unlink('composer-setup.php');"

setup the config php:

define('MAPI_SERVER', 'file:///var/run/kopano/server.sock');

// Authentication realm
define('SABRE_AUTH_REALM', 'Kopano DAV');

// Location of the SabreDAV server.
define('DAV_ROOT_URI', '/var/www/kdav/');

set rights:

chown -R root:www-data /var/www/kdav
chmod 664 /var/www/kdav/config.php

ERRORS!
Tests: 6, Assertions: 1, Errors: 5.

The other thing are the nginx directive (not shure if this are correct and can be working)
i want to implement it to the z-push directive like: https://smtp.domain.com/kdav

i have a few uncommented… but can’t test because composer not running.

Edit: found a simpler install:

curl -sS https://getcomposer.org/installer | sudo php -- --install-dir=/usr/local/bin --filename=composer

@noise
I think you might have a few things backwards here. First of all the depreciation warning itself is harmless, as it is a warning, not an error. So whilst it would be nice for a developer at Kopano to look at this, it won’t stop kdav from working.

A few other observations:

You are running composer install as root, which, as the console output tells you, you shouldn’t be doing. Instead, change to your webserver user and run composer with that.

su nginx -s /bin/bash
cd /var/www/kdav
./composer update
./composer install

I am adding the composer update command because of the output you see in the terminal. I personally have never used that.

The php dav extension you are installing in the beginning is unnecessary as composer downloads all dependencies to the kdav folder. You can hence skip that.

I myself am still struggling to get kdav working (again), so I’ll post back in case I succeed.

Hi All,

ich have the same problem here with german umlaut (ä, ö, ü) as mentioned by MichaelAnders2 and Mornsgrans with CardDAV.

If i check the kdav.log everything seems to be ok … the german umlauts are displayed correct with ä, ö, ü in the log file.

But when i have a look at the kdav created or updated contacts in webapp, deskapp, this letters are not displayed correctly. If i enter german ä, ö, ü, in webapp they are synced to the client with correct enoding.

i have kdav running on Debian 9 with kopano-core 8.7.5.

Manfred

Hi @white-eagle,

which client are you using? Are the umlauts correct when you check the contact in that client?

Manfred

white-eagle

Hi Manfred,

sorry for the late answer.

I built my own CARDDAV client to sync contacts between kopano and our CRM (MS SQL database) automatically.

This kdav.log is for utf8 encoded vcard
The letter Ä was sent with hex codes 0xC3 0x84

As you see … not valid UTF-8 is correct because i used default encoding.

In the first scenario i think i use correct utf8 encoded vCard but the letters are not correct when the contact is stored in kopano address book

I do also have a problem with encoding of Umlauts. I filed an issue here: https://github.com/Kopano-dev/kdav/issues/5#issuecomment-548848833

Manfred

Hi @amaccuish,

there have been some fixes and also more logging. Please update to the latest master branch version.

@june @white-eagle thanks for reporting the umlaut issue. Unfortunately I didn’t have time to debug it more extensively yet.

Hi Norman,

I am also experimenting with KDAV but somewhere I must have an error in its config.

But I always get the error message:

16.11.2019 19:49:14 [25224] [TRACE] dav KopanoDavBackend->Logon(): XXXXXXXXXXX / password

Could someone here so kind and post me a working config of:

the config for the virtual host
the config.php

My KDAV runs in “/var/www/kdav” directory

I am configuring in circles ATM :-(

TIA

Hi @zash1958,

Search for “vcf generated by mapi_mapitovcf:” in the log for a contact with an issue and post that output. Without knowing what’s at line 13 it’s not possible to tell what’s wrong with the data.

Hi @zash1958,

it would be more helpful if you would provide the log as is without editing it. If I use the output from your log it works just fine. However the size of data is different in your log from what I see in mine, so I guess that comes from you editing the log.

If you have a valid Kopano subscription, you can open an issue with the support and send me the issue number so that I can look into it. Otherwise you could upload the log file or the relevant part of it and send me the link.

Hello Manfred,

we have an active subscription. I will compress the log and send it to Kopano itself? Or send it it here to You?

TIA

Hi Uwe,

please send it to Kopano itself (attach the log to the KS issue).

@Fux and @amaccuish,

the “Line starting at X did not follow iCalendar/vCard conventions” issue on zash1958’s system was caused by a contact with multi line additional information (NOTE property in vcard). Could you please check if you have such contacts and if possible to edit the additional information to be in one line and see if it solves the issue?

I’ve created https://jira.kopano.io/browse/KDAV-28 for this problem.

Well sorry for the necroposting but I have created a couple of threads with no answers and saw this thread.
https://forum.kopano.io/topic/3913/kopano-kdav-not-syncing
https://github.com/Kopano-dev/kdav/issues/8

I’m using kdav and have some issues. It seems that Mac Calendar (for macOS Big Sur) is not syncing well with kdav. After some tests it seems that the synchronisation between kdav and kopano-server is not working well. If you create an event in kopano-ical is not synced with mac calendar correctly. Sometimes attendees that you already invited just disappear from the event.

With thunderbird is working fine.

I see this errors in the logs:

Also I can see that MAC Calendar is creating random calendars like this:

Do you guys have issues with mac calendar? I’m using latest version I think.

I’ve also tested ical and z-push and both works well. But ical in webapp has an issue with “all day” option as it takes 2 days instead only one.
