Step 3: Sync your Active Directory
This article is meant for customers who intend to integrate an on-premise active directory with Office 365. If you do not need to integrate an on-premise directory, and intend to provision cloud-only identities, you can skip this step, and proceed to Sync your SIS with School Data Sync.
There are three ways to move your identities to Microsoft 365 Education.
AAD Connect with Password Hash Sync: Recommended Path
The most efficient path to move from an on-premise active directory is using AAD Connect with Password Hash Sync for authentication. This path is easier and cheaper to deploy because you can use Azure AD Connect Express Settings. Express Settings is the default option and is used for the most commonly deployed scenarios. You will only have to manage one server and this path will give you seamless single sign-on, and cloud multi-factor authentication.
AAD Connect with Passthrough Authentication
If you need to manage password authentication requests from your own on-premise active directory, you will still use AAD Connect, but you will need to use the Passthrough Authentication Option instead of Password Hash Sync. Azure Active Directory (Azure AD) Pass-through Authentication enables users to sign in to both on-premises and cloud-based applications using the same passwords. When users sign in using Azure AD, this feature validates users' passwords directly against your on-premises Active Directory. This path is for organizations wanting to enforce their on-premises Active Directory security and password policies.
Active Directory Federated Services (ADFS)
If you need to have on-premise managed Multi-Factor Authentication (MFA), you will need to use Active Directory Federated Services (ADFS). When you choose this authentication method, Azure AD hands off the authentication process to the on-premises Active Directory Federation Services (AD FS) to validate the user’s password. We do not recommend this option unless you need federated single sign-on and on-premise password management. This path is more difficult and expensive, requires the management of multiple servers, and is only relevant for districts with complex security set-up and requirements.
If you’re still not sure which path to choose, use this guide for a comparison of the various Azure AD sign-in methods and how to choose the right sign-in method for your organization.
After you have completed syncing your active directory, please proceed to Step 4 to Sync your SIS with School Data Sync.
