configure and manage directory synchronization by using Azure AD Connect cloud sync

Directory synchronization is a critical component in managing user identities in hybrid environments, where on-premises directories such as Active Directory (AD) need to be integrated with Azure Active Directory (Azure AD). Azure AD Connect cloud sync is one of the tools provided by Microsoft to facilitate this synchronization.

Understanding Azure AD Connect Cloud Sync

Azure AD Connect cloud sync is a lightweight agent that provides synchronization of your on-premises AD with Azure AD, offering an alternative to the traditional Azure AD Connect. The cloud sync model is designed to support complex multi-forest environments with an easier deployment mechanism without the need for a full SQL server, and it is beneficial for scenarios that require rapid provisioning or where resources are constrained.

Cloud sync works by installing an agent on one or more on-premises servers. This agent communicates with a lightweight service in Azure, which in turn orchestrates synchronization with the Azure AD.

Configuring Azure AD Connect Cloud Sync

To configure Azure AD Connect cloud sync, follow the steps below:

1. Prerequisites: Ensure you have the necessary permissions on your Azure AD and AD environments, a global administrator account for Azure AD, and that your on-premises environment meets the necessary requirements, including having Azure AD Connect Health Agent for Sync installed if you are using health monitoring.
2. Installation of the Cloud Sync Agent: Download and install the Azure AD Connect cloud sync agent on your on-premises server. During the installation, you will be prompted to sign in with your global administrator account to authorize the agent.
3. Configure Directory Synchronization: Once the agent is installed, you’ll use the Azure portal to configure the synchronization settings. This involves specifying the on-premises directories to synchronize, as well as the desired synchronization features like password hash synchronization or pass-through authentication.
4. Filtering Objects: Set up filtering to ensure that only the necessary objects (users, groups, contacts) are synchronized. This could include domain-based, organizational unit (OU)-based, or attribute-based filtering.
5. Initial Sync and Scheduling: After configuration, an initial synchronization will occur. You can then set up the synchronization schedule, with options for the frequency of automatic syncs.
6. Monitoring: Use the Azure portal to monitor the synchronization status and health of the cloud sync service. Azure AD Connect Health can provide alerts and performance monitoring to ensure ongoing operation.

Managing Azure AD Connect Cloud Sync

Once you have set up cloud sync, management tasks may include:

• Updating the Agent: Periodically, Microsoft releases updates to the Azure AD Connect cloud sync agent. It’s essential to keep your agent updated to benefit from the latest features and security enhancements.
• Handling Synchronization Conflicts: If synchronization conflicts occur, they must be resolved manually. This may involve adjusting attribute values in AD or Azure AD and re-synchronizing.
• Modifying Synchronization Settings: You can change synchronization options such as the frequency of synchronization, filtering configurations, or the scope of objects synchronized.
• Monitoring and Troubleshooting: Continuous monitoring is essential to proactively identify and resolve issues. You can use Azure AD Connect Health, Azure Monitor, and logs to diagnose and troubleshoot problems.

Advantages of Azure AD Connect Cloud Sync

Use Case Example

Consider a scenario where an organization with multiple AD forests needs to synchronize its user identities with Azure AD. By deploying Azure AD Connect cloud sync, they are able to:

• Streamline the installation process with a lightweight agent.
• Rapidly provision user accounts for new employees across different forests.
• Reduce their on-premises infrastructure overhead by eliminating the need for a dedicated SQL server.
• Easily manage and monitor the synchronization process through the Azure portal and Azure AD Connect Health.
• Keep their synchronization process up-to-date automatically with cloud-delivered updates.

Conclusion

Azure AD Connect cloud sync provides a versatile and efficient way to manage directory synchronization in a hybrid identity environment. By understanding how to configure and manage this tool, administrators can enhance their organization’s security, flexibility, and operational efficiency. It is a vital component of the MS-100 Microsoft 365 Identity and Services exam, as it encapsulates the ability to grasp hybrid identity concepts and apply them practically.
