Z-push 2.1
Contents
Overview
This module can be used to synchronize Emails, Contacts, Tasks and Calendars to a mobile device/tablet.
Dependencies
Apache modules
Some apache modules cannot be enabled because Z-Push is NOT working when they are enabled.

Requirements
Installation
Automatic
To install the z-push module automatically, you can use the script that is provided with the "Sync" module. (install.sh)
The script is located in the "modules/sync/z-push21" folder.
Manual
ActiveSync support does not work out of the box. We use the third party library z-push. To add support of ActiveSync take the following steps (Step 1 to 5 can be done with modules/sync/z-push2/install.sh too):
1. Download z-push from http://zarafa-deutschland.de/z-push-download/final/2.1/. We used version 2.1.0-1750 (But it's probably best to take the latest stable 2.1.x version of z-push).
2. Unpack the archive and put it in the "modules" directory of Group-Office.
3. rename the folder to "z-push21"
4. Copy the folder modules/sync/z-push21/backend/go/ to modules/z-push2/backend/
5. Copy modules/sync/z-push21/config.php to modules/z-push21/config.php
6. Now, you must configure Apache to redirect the URL 'Microsoft-Server-ActiveSync' to the index.php file in the modules/z-push2/ directory.
This can be done by adding the line:
Alias /Microsoft-Server-ActiveSync /path/to/groupoffice/modules/z-push21/index.php
Don't use a symlink, this won't work.
7. Restart apache2 and configure your mobile device with the servername, username and password and you should be in sync!
Known issues per device
| Device | OS | Issue |
|---|---|---|
| Iphone | All IOS versions | Removing participant from a recurring event on the phone that will be saved as an exception event will also delete the participants on the main event |
| HTC | HERO (maybe more) | Contacts that are synced to the phone and then marked as favorite on the phone will not be synced after that anymore. (This will break synchronisation) |
CGI mode
By default z-push only works when PHP is loaded as an Apache module. If you use PHP in CGI mode you'll have to follow this workaround:
Uninstall
Remove the z-push21 folder from the modules directory of Group-Office and remove the apache alias that is described above.

Additional Notes
For debugging change modules/z-push21/config.php:
define('LOGLEVEL', LOGLEVEL_ALL);
A log will be generated in /home/groupoffice/log/
Debugging
Sometimes it can happen that an item is not synced to the device.
Then you get an error in the "z-push-error.log" file that is located in the {go_file_storage_path}/log/z-push/ folder.
The error can look like this:
01/02/2013 12:22:31 [24372] [ERROR] [john@doe.com] Ignored broken message (SyncAppointment). Reason: '4' Folderid: 'a/GroupOfficeCalendar' message id '25' 01/02/2013 12:33:53 [28717] [ERROR] [john@doe.com] Ignored broken message (SyncMail). Reason: '2' Folderid: 'm/INBOX' message id '1674' 01/02/2013 12:34:02 [28717] [ERROR] [john@doe.com] Ignored broken message (SyncMail). Reason: '2' Folderid: 'm/INBOX' message id '1674' 01/02/2013 12:36:35 [13733] [ERROR] [john@doe.com] Ignored broken message (SyncMail). Reason: '2' Folderid: 'm/INBOX' message id '1674'
When this happens you can usually find more info on this error by using the "z-push-admin.php" file that is located in the z-push folder.
This is a commandline tool that is shipped with the z-push2 package.
You can use it like this:
cd /usr/share/groupoffice/modules/z-push21
php z-push-admin.php -a list -u {go_username}
- Note: You need to go to the directory of z-push2 first because otherwise the GO config file cannot be loaded.
If the config file still cannot be found then add this line directly after the <?php open tag in the z-push-admin.php file:
define('GO_CONFIG_FILE',{absolute_path_to_config_file});
When you have ran the z-push-admin tool then you can find a better error description for each device in the result of the "list" command.
