Duo and Azure AD Sync


Currently we have on prem AD that uses Microsoft Azure AD Sync to sync user account with O365. If I enroll users in DUO by using the Azure Active Directory sync will it allow users to login to computer that are join to the local on prem AD? Also, can the user continue to login to those computer by using their sAMAccountName or is the Azure Active Directory sync option only designed for Azure AD joined computers?

Duo’s Azure AD sync only imports users from Azure AD into Duo. It does not apply 2FA to Azure accounts and does not affect Azure login to workstations or online services.

We sync with AzureAD as well. We set the sync to add the attribute onPremisesSamAccountName as an alias. All our computers have the Windows Agent.
