Proxy Settings for Zimbra Desktop in Linux

[soxfan]

Can anyone tell me where to change the proxy server settings for the Zimbra Desktop under Linux? Every day a short time after I launch the Zimbra Desktop I am prompted for a user name and password for my proxy server. This makes sense because the proxy server that it is using requires authentication. However, I'd like to change the proxy settings to another server that does not require authentication and I can't seem to find where this setting lives. I thought it might be tied to another program's settings, but I've checked my .bashrc, Firefox, Konqueror, and Opera but none of them are using this particular proxy server. I've disabled auto updates in the preferences.js file, but I still get prompted at least once a day for the user name and password.

Thanks,
John

Desktop currently doesn't support proxy. It's a roadmap item.

Why then am I prompted to enter my proxy authentication everyday after starting up the desktop? This appears to be related to the software doing a version check or something like that, rather than the desktop going through a proxy to connect to the Zimbra server.

can you attach a screenshot of the prompt?

Screenshot attached (I blurred out a few sections for privacy reasons). This actually came up when I received an email that apparently needed to retrieve some info from the Internet.

You must have some proxy service running on the network that is prompting that dialog to you.

Judging by the screenshot, I think your ZD was loading an HTML message and it's trying to fetch images on that HTML page from another web server - that's what triggered the prompt.

What if you click on a text message or a message that has no image in it, do you still get the same prompt?

Anyway, I don't think that dialog is from ZD.

Sorry to disagree, but this dialog is absolutely from ZD. Note the Zimbra icon in the top left of the authentication box that appears. Also note the bottom left of the ZD screen where it says "Waiting for gw.vtrenz.net". This will stay until I answer the prompt. I never see this window if I don't have ZD running. The box does not come up with normal text messages. I can make this box appear on demand. If I launch ZD and then click on this message or some other one that wants to download images from the the 'Net I get the prompt. After I put it in once I never get the prompt again, unless I close and restart ZD.

Yeah, I take that back. This dialog is from ZD (actually from the XULRunner framework, which is also what Firefox is built on). I guess you have an HTTP proxy setup on your network and it's returning 407 Proxy Authentication Required error - which triggered that dialog. ZD caches your login info, until ZD is restarted.

Let me see if I can find a workaround for you - like caching your login info persistently.

You should be able to use a different proxy server with these lines in your profile/user.js. You need to restart ZD after the change.

user_pref(”network.proxy.http”, “<your proxy server host/ip>″);
user_pref(”network.proxy.http_port”, <your proxy server port>);
user_pref(”network.proxy.type”, 1);
user_pref("network.proxy.no_proxies_on", "localhost, 127.0.0.1");

Thanks for your continued help with this, but unfortunately adding these lines did not solve the problem. I tried adding them to the uesr.js file as you suggested and I also tried adding them to the prefs.js file, which is where I found them in my Firefox profile. I shutdown and restarted ZD from the command line after making the changes, and also tried totally rebooting my PC after the simple command line restart did not work. There were no references to proxy settings in either the user.js and prefs.js prior to me adding these lines, so I still go back to my question of where is ZD getting these settings in the first place? We have a few different proxy servers running. We do not have any network services that would allow an application to automatically pick up the proxy settings. If I use any web app under any operating system, whether it be Linux, Windows, or Mac I am required to manually enter the proxy settings.

I did some additional testing on the same workstation by setting up the Zimbra Desktop under a different Unix account and using a different Zimbra account. I then forwarded along the particular message that I know prompts me for the proxy settings. Under this different account I was never prompted for the proxy settings and the html loaded up fine when I click on the "Display Images" button.

I'm stumped.
