This issue is resolved in KB5008277. |
After installing this update on your Domain Controller (DC), you might have authentication failures on servers relating to Kerberos Tickets acquired via S4u2self. The authentication failures are a result of Kerberos Tickets acquired via S4u2self and used as evidence tickets for protocol transition to delegate to backend services which fail signature validation. Kerberos authentication will fail on Kerberos delegation scenarios that rely on the front-end service to retrieve a Kerberos ticket on behalf of a user to access a backend service. Important Kerberos delegation scenarios where a Kerberos client provides the front-end service with an evidence ticket are not impacted. Pure Azure Active Directory environments are not impacted by this issue. End users in your environment might be unable to sign into services or applications using Single Sign On (SSO) using Active Directory on-premises or in a hybrid Azure Active Directory environment. Updates installed on the client Windows devices will not cause or affect this issue. For more symptoms and specific errors related to this known issue, please see the known issue on Windows Release Health. |
This issue is resolved in KB5008604. |
After installing this update, Microsoft Installer (MSI) might have issues repairing or updating apps. Apps that are known to be affected include some apps from Kaspersky. Affected apps might fail to open after an update or repair has been attempted. |
