With Microsoft’s recent release of Azure Active Directory Sync (AAD Sync), there are now three options for synchronizing your directory with Azure Active Directory, including:
- Azure Active Directory Synchronization Tool (DirSync)
- Azure Active Directory Synchronization Services (AAD Sync)
- Forefront Identity Manager 2010 R2 (FIM)
The release of AAD Sync is significant for organizations that have multiple forests / multiple Exchange Organizations and want to leverage a single Tenant. At present, AAD Sync will likely replace DirSync. However, there are feature differences between the tools, as well as DirSync features that are not supported in AAD Sync (specifically – Password Hash Sync) yet.
