See the article, Choose the right authentication method for your Azure Active Directory hybrid identity solution. Each of these authentication methods can be configured by Azure AD Connect, allowing you to provision users in the cloud.Īzure AD pass-through and password hash authentication are both part of the AAD hybrid authentication solution.Pass-through authentication does not require ADFS or other third-party federation services. Azure AD pass-through authentication provides a password validation mechanism that validate users directly with on-premises Active Directory, outside the cloud.

No additional infrastructure is required. Users are synchronized with Azure AD and password validation occurs in the cloud using the same username and password that is used in on-premises environments.


We are announcing support for Azure AD pass-through and password hash authentication for Azure SQL DB (single database and database pools), Managed Instance, and Azure Synapse (formerly SQL DW).
