We do this, because Azure AD Connect and the Azure AD PowerShell module prompt for modern authentication using Internet Explorer.

We start by disabling the Internet Explorer Enhanced Security Configuration (IE ESC) feature on the Windows Server on which we want to use Azure AD Connect.

We start with configuring the Windows Server on which we will install and run Azure AD Connect.ĭisabling Internet Explorer Enhanced Security Configuration Make sure to sign in with an account that has privileges to create and/or change and link Group Policy objects to the Organizational Unit (OU) in which the systems in scope reside, if you intend to set the items using Group Policy preferences.įor Azure Active Directory, you’ll need an account with the Global administrator or Hybrid Identity administrator role. Sign in with an account with local administrative privileges. Also make sure you install the latest stable version of Azure AD Connect. Make sure all hosts in scope are installed with the latest cumulative Windows Updates. To install Azure AD Connect behind an Internet Proxy, make sure to meet the following requirements: System requirements Beyond this threshold, objects and attributes to synchronize may pile up. In rare situations this might lead to Azure AD Connect synchronization cycles exceeding the 30 minutes threshold. When using Azure AD Connect behind an Internet proxy, this advanced encryption is disabled and the Internet Proxy will use plain TLS when communicating to the Azure AD service endpoints on behalf of Azure AD Connect.īecause Internet proxy servers can be configured to inspect traffic, these systems may introduce lag or latency. This encryption method ensures no system can intervene,or modify the traffic or eavesdrop on the communications in clear text at any stage. Using Azure AD Connect behind an Internet proxy also has big drawbacks however.Īzure AD Connect leverages mutual authentication for encrypting the traffic with TLS (mTLS) to its Azure AD service endpoints. When all other hosts access Internet resources through the proxy, anomalies can be easily detected, reducing the detection time of advanced threats. This traffic can be inspected, filtered and monitored. Instead, the fact that the connection is not a direct connection between the Windows Server running Azure AD Connect and its Azure AD service endpoints is the biggest benefit of using a proxy. Reasons whyīenefits of using an Internet proxy include reduced load times (when an Internet page is served from the Internet proxy’s cache) and filtering of malicious websites, but these benefits don’t really apply to Azure AD Connect due to its nature. Hosts on the network ask the proxy to act on their behalf. I’ll also provide steps along the way to check your connectivity.Īn Internet proxy, or forward proxy acts as an intermediary between hosts on the network and the Internet.

In this post, I’ll show you how to configure the Windows Server host, Azure AD Connect and Azure AD Connect Health to work while meeting this proxy requirement. In many environments, tier 0 systems like Azure AD Connect installations are only allowed Internet access through one or more internet proxy servers. In this series, labeled Hardening Hybrid Identity, we’re looking at hardening these implementations, using recommended practices. Most Microsoft-based Hybrid Identity implementations use Active Directory Federation Services (AD FS) Servers, Web Application Proxies and Azure AD Connect installations.
