Azure AD Connect Requirements

Let’s discuss Azure AD Connect Requirements before installing Azure AD Connect.

Azure AD Connect Requirements

Below are the lists of hardwire software requirements.

Azure AD

You should have an Azure AD tenant. You can get one by creating a free Azure account. If you don’t have an account yet, follow my article How to Create Azure Free Account (Step by Step tutorial) to create an Azure free account.

Active Directory

You can use the Microsoft 365 IdFix tool to identify errors such as duplicates and formatting problems in your directory before synchronizing to Azure Active Directory and Office 365.

The Active Directory schema version must be Windows Server 2003 or later version, and The domain controller used by Azure Active Directory must be writable.

It is recommended to enable the Azure Active Directory recycle bin before proceeding further. This will help you to keep the accidentally deleted Azure AD user object in a soft-deleted state for 30 days. You can restore it based on your needs.

It is not recommended if you want to install Azure AD Connect on a Domain Controller due to security practices that can create problems during Azure AD Connect installation.

Operating system Requirements

Azure AD Connect must be installed on Windows Server 2012 or later version (Windows Server 2012, Windows Server 2012 R2, Windows Server 2016, Windows Server 2019), or else you will get a warning message, and it will not allow you to do the installation. 

If you want to deploy Active Directory Federation Services, then in that case, you need TLS/SSL Certificates, and you need to configure name resolution.

It is recommended to harden your Azure AD Connect server. This will reduce the security attack.

If you want to integrate an Azure AD Global Administrator account for the Azure AD tenant. This account must be a school or organization account.

PowerShell and .NET Framework

You need to install Microsoft PowerShell and .NET Framework 4.5.1 version or a later version installed on your server, as  Azure AD Connect depends on those.

Enable TLS 1.2

Ensure that TLS 1.2 is enabled for Azure AD Connect, and do not forget to install .NET 4.5.1 hotfix.

Hardware requirements for Azure AD Connect

When the number of objects in the Active directory is less than 10,000, the CPU is 1.6 GHz, and the Memory required is 4 GB with a hard disk size of 70 GB.

If the number of objects in the Active directory is between 10,000 and 50,000, then the CPU is 1.6 GHz, and the Memory required is 4 GB with a hard disk size of 70 GB.

If the no of objects in the Active directory is between 150,000–100,000, then the CPU required is 1.6 GHz, Memory required is 16 GB with a hard disk size of 100 GB.

But, when the no of objects in the Active directory is between 100,000–300,000, then the CPU required is 1.6 GHz, and the Memory required is 32 GB with a hard disk size of 300 GB.

While the no of objects in the Active directory is between 300,000–600,000, the CPU required is 1.6 GHz, Memory required is 32 GB with a hard disk size of 450 GB.

If the no of the object in Active Directory is more than 600,000, then the CPU required is 1.6 GHz, and the Memory required is 32 GB with a hard disk size of 500 GB.
