AADSYNC e proxy issue

  • Article

Are you going to install AADSYNC behind a proxy?

Well, you need to do two things:

  1. Configure your proxy server to get some office 365 URLs in anonymous (no authentication)
  2. Configure AADSYNC to use proxy server

Configure your proxy server

Configure proxy server as indicate in this URL Office 365 URLs and IP address ranges:

https://technet.microsoft.com/en-us/library/hh373144.aspx

Configure AADSYNC

You have to configure proxy settings on internet explorer for service user, you can do that in this way:
runas /user:domain\serviceuser "control.exe inetcpl.cpl"

If you continue to have problem after configure Internet Explorer then you must configure machine.config in .NET45 Framework
C:\Windows\Microsoft.NET\Framework64\v4.0.30319\Config\machine.config
Add this section to bottom of file, be aware it's case sensitive:

<system.net>

<defaultProxy>

<proxy usesystemdefault="true" proxyaddress="https://proxy-ip:80" bypassonlocal="true" />

</defaultProxy>

</system.net>

    Hi,

    In case you don't know the credentials of the service user, like when it's the auto created user, you can't set the proxy by running: runas /user:domainserviceuser "control.exe inetcpl.cpl"
    However, you can edit the registry and manually set the "ProxyServer" entry under: HKEY_USERS\SoftwareMicrosoftWindowsCurrentVersionInternet Settings" and make sure the "ProxyEnable" DWORD is set to 1.

    At least in our case this worked.
