Unzip (or use git clone) the sourcecode of Kopano WebApp to a new directory. In this README we call the source folder of WebApp "kopano-webapp-source".

Then generate the WebApp build utils:

cd kopano-webapp-source
ant tools

Next clone the plugin to the WebApp plugin directory:

cd kopano-webapp-source\plugins
git clone https://git.sprinternet.at/zarafa_webapp/calendarimporter.git

Now lets build the plugin:

cd kopano-webapp-source\plugins\calendarimporter\php
composer install
cd kopano-webapp-source\plugins\calendarimporter
ant deploy

The compiled plugin is saved to kopano-webapp-source\deploy\plugins\calendarimporter.

Installing the plugin

From compiled source

Copy the whole folder "calendarimporter" to your production WebApp (kopano-webapp-production\plugins\calendarimporter)

For example:

cp -r kopano-webapp-source\deploy\plugins\calendarimporter kopano-webapp-production\plugins\

Installing the sync backend

From source

Copy the whole folder "kopano-webapp-source\plugins\calendarimporter\backend" to a destination of cour choice.

For example:

cp -r kopano-webapp-source\plugins\calendarimporter\backend /opt/ical-sync/backend

From precompiled download

Download the newest backend release from https://git.sprinternet.at/zarafa_webapp/calendarimporter/tree/master/DIST.

Unzip the downloaded file and copy the backend folder to a destination of cour choice.

For example:

cp -r Downloads\calendarimporter_backend /opt/ical-sync/backend

WebApp Plugin Configuration

Edit the config.php file in the plugin root path to fit your needs.

Available configuration values:

Configuration Value	Type	Default	Desctription
PLUGIN_CALENDARIMPORTER_USER_DEFAULT_ENABLE	boolean	false	Set to true to enable the plugin for all users
PLUGIN_CALENDARIMPORTER_USER_DEFAULT_ENABLE_SYNC	string	true	Set to true to enable the sync feature for all users
PLUGIN_CALENDARIMPORTER_DEFAULT	string	"Kalender"	Default calendar folder name (might be "Calendar" on english installations)
PLUGIN_CALENDARIMPORTER_DEFAULT_TIMEZONE	string	"Europe/Vienna"	The local Timezone
PLUGIN_CALENDARIMPORTER_TMP_UPLOAD	string	"/var/lib/kopano-webapp/tmp/"	Temporary path to store uploaded iCal files

Sync Backend Configuration

First you have to create a new Kopano user with admin rights. For example:

kopano-admin -c adminuser -e admin@domain.com -f "Calendar Sync Admin" -p topsecretpw -a 1

Then edit the config.php file of the sync backend to fit your needs.

Available configuration values:

Configuration Value	Type	Default	Desctription
$ADMINUSERNAME	string	"adminuser"	The newly created Kopano admin user
$ADMINPASSWORD	string	"topsecretpw"	The password of the admin user
$SERVER	string	"http://localhost:236/kopano"	Kopano Socket or HTTP(S) connection string
$CALDAVURL	string	"http://localhost:8080/ical/"	Kopano CalDAV URL
$TEMPDIR	string	"/tmp/"	Temporary path to store synchronised iCal files (must be writeable by the user executing the sync script)

Next set up a cronjob to allow periodic syncing of ical items.

For example: (/etc/crontab):

# sync ics calendars every minute (interval can be changed by the user)
* * * * * icssync /opt/ical-sync/backend/sync.php > /var/log/icssync.log 2>&1

If you get an error, make sure that the mapi module is loaded for php-cli. Therefore create or modify: /etc/php7/cli/conf.d/50-mapi.ini

extension=mapi.so

Do no run the sync script as root! Create a user without admin rights (adduser icssync), and change permissions of the tmp folder accordingly.

Usage

The plugin add context menu entries to calendar folders.

If syncing is enabled, the calendar section in the WebApp settings gets extended with a synchronisation overview. There you can add new iCal URLs for syncing.
