What is Azure AD Connect?
Azure AD Connect is an on-premises Microsoft application that's designed to meet and accomplish your hybrid identity goals. If you're evaluating how to best meet your goals, you should also consider the cloud-managed solution Azure AD Connect cloud sync.
Azure AD Connect provides the following features:
- Password hash synchronization - A sign-in method that synchronizes a hash of a users on-premises AD password with Azure AD.
- Pass-through authentication - A sign-in method that allows users to use the same password on-premises and in the cloud, but doesn't require the additional infrastructure of a federated environment.
- Federation integration - Federation is an optional part of Azure AD Connect and can be used to configure a hybrid environment using an on-premises AD FS infrastructure. It also provides AD FS management capabilities such as certificate renewal and additional AD FS server deployments.
- Synchronization - Responsible for creating users, groups, and other objects. As well as, making sure identity information for your on-premises users and groups is matching the cloud. This synchronization also includes password hashes.
- Health Monitoring - Azure AD Connect Health can provide robust monitoring and provide a central location in the Azure portal to view this activity.
Azure AD Connect Health for Sync requires Azure AD Connect Sync V2. If you are still using AADConnect V1 you must upgrade to the latest version. AADConnect V1 is retired on August 31, 2022. Azure AD Connect Health for Sync will no longer work with AADConnect V1 in December 2022.
