If your legacy applications don't use NTLM authentication or LDAP simple binds, we recommend that you disable NTLM password hash synchronization for Azure AD DS. Legacy password hashes aren't used if you only use Azure AD Connect to synchronize an on-premises AD DS environment with Azure AD. The account isn't synchronized from Azure AD to Azure AD DS until the password is changed.įor users synchronized from an on-premises AD DS environment using Azure AD Connect, enable synchronization of password hashes.Īzure AD Connect only synchronizes legacy password hashes when you enable Azure AD DS for your Azure AD tenant. This password change process causes the password hashes for Kerberos and NTLM authentication to be generated and stored in Azure AD. Therefore, Azure AD can't automatically generate these NTLM or Kerberos password hashes based on users' existing credentials.įor cloud-only user accounts, users must change their passwords before they can use the managed domain. For security reasons, Azure AD also doesn't store any password credentials in clear-text form.
Azure AD doesn't generate or store password hashes in the format that's required for NTLM or Kerberos authentication until you enable Azure AD DS for your tenant. To authenticate users on the managed domain, Azure AD DS needs password hashes in a format that's suitable for NT LAN Manager (NTLM) and Kerberos authentication. These custom policies can then be applied to specific groups of users as needed.įor more information on the differences in how password policies are applied depending on the source of user creation, see Password and account lockout policies on managed domains. You can create your own custom password policies to override the default policy in a managed domain. A few settings, like minimum password length and password complexity, only apply to users created directly in a managed domain. Settings like account lockout policy apply to all users in a managed domain, regardless of how the user was created as outlined in the previous section. As synchronization is one way from Azure AD, user accounts created in the managed domain aren't synchronized back to Azure AD.Īzure AD DS includes a default password policy that defines settings for things like account lockout, maximum password age, and password complexity. If you need to create service accounts for applications that only run in the managed domain, you can manually create them in the managed domain.The user account can be manually created in a managed domain, and doesn't exist in Azure AD.The majority of user accounts in a managed domain are created through the synchronization process from Azure AD.This includes cloud-only user accounts created directly in Azure AD, and hybrid user accounts synchronized from an on-premises AD DS environment using Azure AD Connect. The user account can be synchronized in from Azure AD.Some features, like initial password synchronization or password policy, behave differently depending on how and where user accounts are created. You can also manually create accounts directly in the managed domain. Most user accounts are synchronized in from Azure AD, which can also include user account synchronized from an on-premises AD DS environment. User accounts can be created in a managed domain in multiple ways. You can use the Active Directory Administrative Center or Microsoft Management Console (MMC) snap-ins like DNS or Group Policy objects, for example.

Instead, you create a management VM that's joined to the managed domain, then install your regular AD DS management tools. You can't sign in to these DCs to perform management tasks. For redundancy, two DCs are created as part of a managed domain. In a managed domain, the domain controllers (DCs) that contain all the resources like users and groups, credentials, and policies are part of the managed service. Domain managementĪ managed domain is a DNS namespace and matching directory.

This conceptual article details how to administer a managed domain and the different behavior of user accounts depending on the way they're created.
There's also some differences in behavior for password policies and password hashes depending on the source of the user account creation. You use the same administrative tools in Azure AD DS as a self-managed domain, but you can't directly access the domain controllers (DC). When you create and run an Azure Active Directory Domain Services (AD DS) managed domain, there are some differences in behavior compared to a traditional on-premises AD DS environment.
