2024-06 Cumulative Update has an accidental Microsoft bug that will make Domain Controllers stop calling the AuthLite module (thus breaking the authentication of all AuthLite Users.)

Please install version 2.5.16 or later from the downloads page to work around this problem.

Affected OS:

  • Server 2022 domain controllers that have installed June 2024 (KB5039227) update or any later update containing the same change. Microsoft updates are now cumulative so you cannot simply block one update and avoid the problem.
  • Server 2019 domain controllers that have installed June 2024 (KB5039217) update or any later update containing the same change. Microsoft updates are now cumulative so you cannot simply block one update and avoid the problem.

Not Affected:

  • Other OS version domain controllers
  • Non-domain-controllers.

If your DCs already updated, please log in with a 1-factor break-glass/emergency account to install the new AuthLite version, then reboot.
