My environment:

Zimbra Server:
SLES 10 SP3
Zimbra OSS 7.0.1 + Godaddy SSL Certs

Z-Push server:
SLES 11 SP1
Z-Push 1.5.5
Z-Push Zimbra Backend Release 51
Apache 2 + php5 + php-curl + Godaddy SSL Certs

The above configuration that needs to be done on the config.php file is perfect, no need to do anything else.

The whole secret is: DO NOT attempt to put Z-Push on the same web server where Zimbra is. It’s not worth it.

Before doing this I was stuck on this error:

problem accessing /service/extension/zimbrasync. reason:
system failure: extension http handler not found at /zimbrasync
powered by jetty://

Now we have Sync’d an iPhone 3GS using iOS 5 and a Samsung Galaxy Tab. Calendar, contact and task sync perfect. Mail comes, mail goes… Can’t see how can this get any better.

Best regards,
Raul

I had this same problem with revision 50 and found it was in issue in “function SoapRequest” in the zimbra.php file. In revision 50 this is at line 6752 and the code with the issue is at line 6800. The code is attempting to check if the session id has changed during a SOAP request. The error is that during an “ENDSESSIONREQUEST” there is no sessionid token in the SOAP response. All I did was comment out this lines of code as follows:

/*
$newSessionId = $this->ExtractSessionID($response);
if (!isset($this->_sessionid)) {
debugLog( ‘Session Id – NEW ['.$newSessionId.']‘ );
$this->_sessionid = $newSessionId;
} else if ($newSessionId != $this->_sessionid) {
debugLog( ‘Session Id changed – OLD ['.$this->_sessionid.'] -> NEW ['.$newSessionId.']‘ );
$this->_sessionid = $newSessionId;
$this->_sessionIdChanged = true;
}

if (defined(‘ZIMBRA_DEBUG’)) {
if ((ZIMBRA_DEBUG === true) || (stripos(ZIMBRA_DEBUG, $this->_username) !== false)) {
debugLog(‘SOAP response: ‘.$response);
}
}
*/

This is a bit of a brute force approach as the code is valid for other SOAP request types so should only be bypassed for the “ENDSESSIONREQUEST”.

Anyway, this will get you round the problem for the moment. I will look at the code again and create a more selective change and post it to the Zimbra BackEnd site.

Hello,

I get this message in the debug after loading my folders:
Session Id changed – OLD [1854] -> NEW []

Z-push : 1.5.2
backend : 49

I have never been able to sync !

Help please !

I get the error listed above and after researching it.. I keep ending up with; “if it’s the open source version” then you’re out of luck. Buy the network edition.

The whole purpose of this post is to do this without having to buy the Network Edition.

Anyone have some up to date instructions?

I’m using Debian Squeeze and Zimbra ZCS 6.0 Open Source Edition.

Thanks.
Zack

i fixed it by myself with the following codechanges in line 165 of index.php:
// Do the actual request
if ($_SERVER["REQUEST_METHOD"] == ‘GET’ && $cmd == ‘OPTIONS’) {
header(“MS-Server-ActiveSync: 6.5.7638.1″);
header(“MS-ASProtocolVersions: 1.0,2.0,2.1,2.5″);
header(“MS-ASProtocolCommands: Sync,SendMail,SmartForward,SmartReply,GetAttachment,GetHierarchy,CreateCollection,DeleteCollection,MoveCollection,FolderSync,FolderCreate,FolderDelete,FolderUpdate,MoveItems,GetItemEstimate,MeetingResponse,ResolveRecipients,ValidateCert,Provision,Search,Ping”);
debugLog(“Options request”);

}
switch($_SERVER["REQUEST_METHOD"]) {

i allways getting “could not open connection” (German: Die Verbinung zu Server kann nicht geöffnet werden), but i can see the connection in the Apache-Log and in the debug.txt.

I tried the new Revision : 46 (11-Nov-2010) and the version descripted in this howto.

I open the connection via WLAN.

If i enable ZIMBRA_DEBUG, i can see my mail-folders.
My config.php:
define(‘PROVISIONING’, false);

$BACKEND_PROVIDER = “BackendZimbra”;
define(‘ZIMBRA_USER_DIR’, ‘zimbra’);
