    Default ZCO and squid proxy

    Hi,

    I have one user who wants to access our Zimbra Server with Outlook/ZCO through a authenticating squid http proxy.

    I was pretty sure that this should work as I saw the proxy configuration dialog during the ZCO installation before. But ZCO does not seem to connect to the proxy. I doublechecked that the proxy settings are correct.

    What could be the problem here? Are there known issues about authenticating proxies and ZCO?
    BTW: Username and Password for the http proxy are not the same as the Zimbra Account credentials...

    Regards
    Thomas

    have you tried to configure the proxy settings in IE and have ZCO use the IE settings?

    I tried both (IE Settings and to configure the proxyserver dirctly into ZCO). I had no success. I could verify, that ZCO did not even connect to the proxy (no log entry in the squid).

    How can I debug that?

    Hi,

    I installed winhttptracecfg. I can see, that the ZCO connects to the squid http proxy (I can also see entries in the squid access log). The squid returns "authentication required" but the ZCO does not open a dialog for the basic authentication....

    The question is: what is the expected behaviour? Is it simply not supportet (ZCO through authenticating proxy), or is it a bug, that the auth dialog is not raised...

    Regards
    Thomas

    Hi Thomas,
    unfortunately this is a big problem for my organization.
    Manager using outlook aren't able to gain access to Zimbra when they work connected to Company intranet because of proxy validation (Zimbra front end is located in DMZ).
    When they are outside, connected via internet provider, all works fine.
    I think should be time for me to open a ticket about that.
    Thanks for your quick answer.
    All the best
    Diego

    Are there any news on this? I found a bugreport/RFE on this:
    Bug 28437 – support proxy authentication with ZCO

    I have users behind a squid proxy with authentication.
    Some of them want to use Outlook.

    @archery57: don't forget to vote for this bug...
