Here's a summary of the express installation process:

Before installing Azure AD Connect, ensure you have the necessary prerequisites and system requirements in place. This includes an Azure subscription, an on-premises server running Windows Server 2016 or later, and a functional on-premises Active Directory.

After you've installed Azure AD Connect, you'll need to configure it to meet your organization's needs. To do this, start by following the next steps to configure sync features, which include configuring filtering, password synchronization, and password writeback.

You can find more information on these topics by visiting the relevant links in the Azure AD Connect sync section. For example, to configure filtering, head to the Azure AD Connect sync: Configure filtering page.

To ensure your users are set up correctly, you'll also need to configure password writeback, which can be done by following the steps outlined in the Getting started with password management article.

In addition to these features, you may also want to consider enabling device writeback, which can be found in the Enabling device writeback in Azure AD Connect article.

Here are some key next steps to keep in mind:

By following these steps and configuring Azure AD Connect to meet your organization's needs, you'll be able to ensure a smooth and secure implementation of Azure Active Directory.

To ensure a successful Azure AD Connect implementation, proper planning is key. Proper planning should include consideration of established best practices, such as verifying network connectivity and firewall settings.

Network connectivity is a critical aspect of Azure AD Connect. Ensure that the required ports and protocols are allowed through firewalls and that there is reliable communication between your on-premises Active Directory and Azure AD.

Regularly backing up your Azure AD Connect configuration settings and customizations is essential. This ensures that you can quickly restore your synchronization setup in the event of a failure or the need to reinstall Azure AD Connect.

To protect the server running Azure AD Connect, treat it like a domain controller. Limit administrative rights and login permissions, and control physical access to the server.

Only those who install the sync engine, and admins of the local machine, can access Azure AD Connect by default. You can add more users to the ADSyncAdmins group on the local server, but be very selective about who you allow to access it.

Here's a summary of the best practices for controlling access to Azure AD Connect:

By following these best practices, you can ensure a secure and robust hybrid identity infrastructure.

Azure AD Connect offers a range of features and functionalities that make it a powerful tool for managing your hybrid identity solution.

Group writeback is one of these features, allowing you to synchronize groups created in Azure AD back to your on-premises Active Directory.

This seamless integration enables you to manage your groups in one place, simplifying the process of group management.

Device registration is another feature of Azure AD Connect, ensuring that devices are integrated into your hybrid identity solution with minimal hassle.

Federation Integration is a powerful feature in Azure AD Connect that allows you to share access and resources across multiple domains. This can be a game-changer for organizations with multiple offices or subsidiaries.

By federating your on-premises environment with Azure AD, you can ensure all user authentication occurs on-premises and implement rigorous access control. This is especially important for organizations with sensitive data that need to be protected.

A federation is essentially a collection of domains with established trust for sharing access and resources. You can think of it like a network of trusted domains that can share information and resources securely.

Azure AD Connect provides several features that simplify federating with Azure AD using AD FS and managing your federation trust. These features include updating SSL certificates, adding AD FS servers to expand the farm, and repairing the trust with Azure AD.

Here are some key benefits of federation integration:

If your ADFS server has not been configured to automatically update certificates from Azure AD, you'll be notified when it's time to update them. This ensures that your federation trust remains secure and up-to-date.

By taking advantage of federation integration with Azure AD Connect, you can simplify the process of sharing access and resources across multiple domains and improve the overall security and efficiency of your organization.

Password hash synchronization is a crucial element in maintaining a secure hybrid identity environment.

This feature allows users to sign in with their on-premises passwords when accessing cloud resources, without exposing the actual password.

Azure AD Connect synchronizes a hash of the user's password from an on-premises Active Directory instance to a hash of the user's password in a cloud-based Azure AD instance.

Password hash synchronization enables on-premise users to sign in to Azure AD services like Microsoft 365 using the same password as they do for the on-premises Active Directory.

Leaked credential detection is also enabled for hybrid accounts, which helps protect users from compromised credentials.

Microsoft works with law enforcement agencies and dark web researchers to find publicly available username and password pairs, and if credentials belonging to users match those available on the dark web, the associated account is moved to high risk.

Group writeback is a feature that allows groups created in Azure AD to be synchronized back to the on-premises Active Directory. This ensures that group membership is consistent across both environments.

Device registration is another optional feature that ensures seamless integration of devices into your hybrid identity solution.

Attribute mapping is a key feature in Azure AD Connect that allows you to fine-tune attribute mappings and transformations.

This means you can ensure that user attributes align with your organization’s needs, previous customizations, and security policies.

With attribute mapping, you have the flexibility to tailor your attribute requirements to fit your organization's unique needs.

Azure AD Connect enables you to make these adjustments, giving you more control over how user attributes are handled.
