- Addresses an issue that may cause a temporary KRB_AP_ERR_MODIFIED Kerberos sign-in failure in applications and services configured to use a Group Managed Service Account (GMSA). This issue occurs after the automatic update of the service account password.
- Addresses an issue that causes a sign-in to fail with the error, “Incorrect Username or password” when using an empty or null password and Windows Defender Credential Guard is enabled.
