 Azure Policy can enforce the creation of an Azure SQL Database or Azure SQL Managed Instance with [Azure AD-only authentication](authentication-azure-ad-only-authentication.md) enabled during provisioning. With this policy in place, any attempts to create a [logical server in Azure](logical-servers.md) or managed instance will fail if it isn't created with Azure AD-only authentication enabled.
 
 The Azure Policy can be applied to the whole Azure subscription, or just within a resource group.
