We recommend updating any domain controllers with 4.1.0 installed to 4.1.1 before attempting to install the latest available version. Version 4.1.1, released July 13, 2020, corrects this issue and is suitable for installation on domain controllers, member servers, and workstations. There is a known issue with installation of the latest release of Duo Authentication for Windows Logon and RDP, version 4.1.0, on Active Directory domain controllers that may trigger user lockouts.
General Are there any issues installing Duo for Windows Logon on Active Directory domain controllers? Duo integrates with Microsoft Windows client and server operating systems to add two-factor authentication to Remote Desktop and local logons.
