Microsoft released the May Cumulative Upgrade a few days back. This update is available for all Windows versions. It was discovered that the update not only contains fixes but also introduces problems that can cause disruption to the operation of certain platform services. The software giant acknowledged the issue and will likely release a patch shortly to address it.
Based on available data, these packages are KB5013943 and KB5013942, respectively, for Windows 11. (build 22000.675). Installation of the cumulative update could cause server and client OS authentication failures in a range of services, including Network Policy Server and Routing and Remote Access Service, Extensible Authentication Protocol and Protected Extensible Authentication Protocol. According to the source, the problem lies in the way that the domain controller maps user machine accounts with mapping certificates. The issue does not affect non-domain-controlled client and server OS versions.
Microsoft is currently working to fix the mentioned bugs. The exact date when the patch will become available is unknown. Users experiencing problems after installing the cumulative updates are advised not to use Active Directory.
