Z-Push v2 with Zimbra

The procedure below should get you up and running so you can sync your mobile device to your Zimbra server using Active-Sync provided by Z-Push.

It doesn't include setting up provisioning, which is the Active-Sync feature that enhances security by providing a mechanism to remote wipe your devices, enforce storage encryption etc. See the forum thread above if you want to know how to set it up.

Do not attempt to install Z-Push on the same server as Zimbra.

It is possible, but will require you to hack your Zimbra installation, and performing a Zimbra upgrade will probably break Z-Push. If you must do it, then your best bet is to install on separate server first. Then, once you know you've got a working installation, try to get Z-Push running on your Zimbra server.

The following procedure assumes that you have a web-server that's accessible from the internet. Mine is an Apache2 webserver, running on Ubuntu 10.04 LTS, therefore any references to commands, paths, etc, will have come from that set-up.

If you are upgrading from Z-Push v1 its recommended that you start from scratch; move your old installation to a different folder (eg mv /var/ww/z-push /var/www/z-push-v1), then install v2 to /var/ww/z-push. Client devices shouldn't need to have their accounts re-added/re-sync'ed following the new install as Z-Push should manage this anyway. However I found that this doesn't always work properly and have ended up needing to re-add accounts to some mobile devices.

Set-up

See the following sections for Apache configuration...

• Apache Config
• Apache SSL Config

1. If you don't have them, install subversion and php-curl
   • apt-get install subversion php5-curl
2. Create a folder for Z-Push on your webserver
   • EG mkdir /var/www/z-push
3. Download the latest Z-Push version (see http://z-push.sourceforge.net/soswp/index.php?pages_id=39&t=Download) to a temp folder and unpack
   • EG wget http://zarafa-deutschland.de/z-push-download/final/2.0/z-push-2.0.3-1467.tar.gz
   • EG tar -zxvf z-push-2.0.3-1467.tar.gz
4. Move the contents to your webserver folder
   • EG mv z-push-2.0.3-1467/* /var/www/z-push/
5. Create folders for state (/var/lib/z-push) and log data (/var/log/z-push) and make writable by the webserver (can be altered in config.php file)
   • mkdir /var/lib/z-push
   • mkdir /var/log/z-push
   • EG chgrp www-data /var/lib/z-push
   • EG chmod g+w /var/lib/z-push
   • EG chgrp www-data /var/log/z-push
   • EG chmod g+w /var/log/z-push
6. Download the Zimbra Z-Push backend into a /zimbra folder under backend
   • EG svn checkout https://zimbrabackend.svn.sourceforge.net/svnroot/zimbrabackend/zimbra-backend/branches/z-push-2 /var/www/z-push/backend/zimbra
7. Update the Z-Push config.php file as required (see example below - Z-Push Config)

Z-Push Config

// Update existing fields in config
define('TIMEZONE', 'Europe/London"');
define('PROVISIONING', false);
$BACKEND_PROVIDER = "BackendZimbra";

// Add to config
define('ZIMBRA_URL', 'https://mail.sandfordit.com')
define('ZIMBRA_SYNC_CONTACT_PICTURES', true);
define('ZIMBRA_VIRTUAL_CONTACTS',true);
define('ZIMBRA_VIRTUAL_APPOINTMENTS',true);
define('ZIMBRA_VIRTUAL_TASKS',true);
define('ZIMBRA_IGNORE_EMAILED_CONTACTS',true);
define('ZIMBRA_HTML',true);
define('ZIMBRA_ENFORCE_VALID_EMAIL',true);
define('ZIMBRA_RETRIES_ON_HOST_CONNECT_ERROR',3);
define('ZIMBRA_DEBUG',true);

See http://php.net/manual/en/timezones.php for the correct name for your local timezone

Mobile Device Setup

To sync devices via Active Sync add the account details as an Microsoft Exchange or Active Sync account.

Do not select to sync SMS - the Active Sync protocol that Z-Push uses supports it, but Zimbra does not.
