Z-Push with HA Zimbra Architecture . Proxy issue

thctlo

have you tried to change :

define(‘ZIMBRA_URL’, ‘http://proxy.domain.tld’);

to

define(‘ZIMBRA_URL’, ‘https://proxy.domain.tld’);

Please note, i dont know zimbra, but i did see: https://sourceforge.net/p/zimbrabackend/support-requests/167/
and maybe you can use this info : https://forums.zimbra.org/viewtopic.php?t=60300#p270549

Yes already tried theses workaround.

We can see an 401 authentication error … We tried to manually send the soap request and it works :(

i also found this one.
https://forum.kopano.io/topic/682/z-push-behind-basic-authentication
check if this also applies to your setup.

and check if your upgrade replaced a setting or more.

/var/www/html/z-push/backend/zimbra/config.php

check if you server is in the config.php

For me, im out of thoughts… i do think this is a zimbra problem and it looks like zimbra is not detecting some z-push settings.

not my case the authentication is validated by a SSO. I unable a debug in the PHP code and see an error on the soap response .

I think is a problem with the source code because even if i configure my preproduction z-push to communicate with my Zimbra server (8.0.7) in production, it’s doesn’t work. I got the same error.

A thing you could try also, is to disable gzip on the webserver running the z-push vhost.
That might fix the SOAP content truncated 0!=687 part
I’ve found some other things you can read, maybe it helps.

Look at : https://github.com/iomarmochtar/ozpy maybe thats an option

You could try to setup with https://xdebug.org/ a php debug extention.

and these maybe related
https://bugzilla.zimbra.com/show_bug.cgi?id=99482
https://bugzilla.zimbra.com/show_bug.cgi?id=75827

So i suggest, report this bug at zimba.

Re,

after wide troubleshooting it’s should be an issue with Transfer-Encoding: chunked . The response size doesn’t match the attended size … We have tried all way rproxy, proxy, zimbra no luck :(
Maybe a curl issue … troubleshooting again …

oloncle

Got it !: The issue is due to a encoding problem, forcing a soap request in UTF-8 works … why the web server is not working correctly will be the last question !

Come back asap with the workaround !

Anybody has already implemented z-push with Zimbra 8.8.7 ?

I have set up a test instance of zimbra 8.8.8 on Centos 7, with z-push 2.4.2.beta1+0 and zimbra backend 68 running on Centos 6/Apache 2.4.latest and everything looks to work correctly.

Check your php.ini setting for the directive

default_charset = “UTF-8”

and your HTTPD settings for the directive

AddDefaultCharset UTF-8

By the way, if you use RH/Centos with the sclo repositories, the php.ini file is not necessarily in the normal place - in my case the active one is found at /opt/etc/rh/rh-php70/php.ini

Always a good idea when troubleshooting to first create a phpinfo.php file

<?php
phpinfo();
?>

and see where it tells you it is picking up the php.ini file from.

Configuration File (php.ini) Path /etc/opt/rh/rh-php70
Loaded Configuration File /etc/opt/rh/rh-php70/php.ini

Did you edit the source zimbra.php file after downloading it?

By default, all editing is done using Notepad++ with Encoding set to UTF-8. This should cause it to be interpreted by the web server as UTF-8, and to send requests/expect responses in UTF-8.

If you edited the file with an editor that saved it in any other Encoding format then that could be the source of your issue.
