Work with existing on-premises proxy servers

  • Článok

This article explains how to configure the Intune Connector for Active Directory to work with outbound proxy servers. It's intended for customers with network environments that have existing proxies.

By default, the Intune Connector for Active Directory will attempt to automatically locate a proxy server on the network using Web Proxy Auto-Discovery (WPAD). If this has been configured on your network, other configuration may not be required. When changes are needed, the following sections describe how to override the default settings, using the standard .NET Framework capabilities for configuring proxy settings. More options are described in that documentation.

For more information about how connectors work, see Understand Microsoft Entra application proxy connectors.

Completely bypass outbound proxies

You can configure the connector to bypass your on-premises proxy to ensure it uses direct connectivity to the Azure services. We recommend this approach, as long as your network policy allows for it, because it means that you have one less configuration to maintain.

To disable outbound proxy usage for the connector, edit the :ProgramFiles%\Microsoft Intune\ODJConnector\ODJConnectorSvc\ODJConnectorSvc.exe.config file and set the default proxy to "False" as shown in the following code example:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <system.net>  
        <defaultProxy>   
            <defaultProxy enabled="False" /> 
        </defaultProxy>  
    </system.net>
    <runtime>
        <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
            <dependentAssembly>
                <assemblyIdentity name="mscorlib" publicKeyToken="b77a5c561934e089" culture="neutral"/>
                <bindingRedirect oldVersion="0.0.0.0-2.0.0.0" newVersion="4.6.0.0" />
            </dependentAssembly>
        </assemblyBinding>
    </runtime>
    <startup> 
        <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.6" />
    </startup>
    <appSettings>
        <add key="SignInURL" value="https://portal.manage.microsoft.com/Home/ClientLogon"/>
        <add key="LocationServiceEndpoint" value="RestUserAuthLocationService/RestUserAuthLocationService/ServiceAddresses"/>
    </appSettings>
</configuration>

To ensure that the Connector Updater service also bypasses the proxy, make a similar change to C:\Program Files\Microsoft Intune\ODJConnector\ODJConnectorSvc\ODJConnectorSvc.exe.config.

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <system.net>  
        <defaultProxy>
            <defaultProxy enabled="False" /> 
        </defaultProxy>  
    </system.net>
    <startup>
        <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.6" />
    </startup>
    <appSettings>
        <add key="BaseServiceAddress" value="https://manage.microsoft.com/" />
    </appSettings>
</configuration>

Be sure to make copies of the original files, in case you need to revert to the default .config files.

Once the configuration files have been modified, you'll need to restart the Intune Connector service.

  1. Open services.msc.
  2. Find and select the Intune ODJConnector Service.
  3. Select Restart.

Specifying an alternative proxy server

If a different proxy server (for example, one that bypasses authentication) needs to be used with the Intune Connector for Active Directory, this can be specified in a similar manner. To use a different proxy, edit the :\Program Files\Microsoft Intune\ODJConnector\ODJConnectorUI\ODJConnectorUI.exe.config file and add the proxy address and proxy port in the section shown in this code sample:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <system.net>  
        <defaultProxy>   
            <proxy proxyaddress="<PROXY ADDRESS HERE>:<PORT HERE>" bypassonlocal="True" usesystemdefault="True"/>   
        </defaultProxy>  
    </system.net>
    <runtime>
        <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
            <dependentAssembly>
                <assemblyIdentity name="mscorlib" publicKeyToken="b77a5c561934e089" culture="neutral"/>
                <bindingRedirect oldVersion="0.0.0.0-2.0.0.0" newVersion="4.6.0.0" />
            </dependentAssembly>
        </assemblyBinding>
    </runtime>
    <startup> 
        <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.6" />
    </startup>
    <appSettings>
        <add key="SignInURL" value="https://portal.manage.microsoft.com/Home/ClientLogon"/>
        <add key="LocationServiceEndpoint" value="RestUserAuthLocationService/RestUserAuthLocationService/ServiceAddresses"/>
    </appSettings>
</configuration>

To ensure that the Connector Updater service also bypasses the proxy, make a similar change to C:\Program Files\Microsoft Intune\ODJConnector\ODJConnectorSvc\ODJConnectorSvc.exe.config.

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <system.net>  
        <defaultProxy>   
            <proxy proxyaddress="<PROXY ADDRESS HERE>:<PORT HERE>" bypassonlocal="True" usesystemdefault="True"/>   
        </defaultProxy>  
    </system.net>
    <startup>
        <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.6" />
    </startup>
    <appSettings>
        <add key="BaseServiceAddress" value="https://manage.microsoft.com/" />
    </appSettings>
</configuration>

Be sure to make copies of the original files, in case you need to revert to the default .config files.

Once the configuration files have been modified, you'll need to restart the Intune Connector service.

  1. Open services.msc.
  2. Find and select the Intune ODJConnector Service.
  3. Select Restart.
