    • (December 16, 2013) Microsoft has released KB2909569 which is an update that fixes issues and adds support to MDM client in Windows RT 8.1 and Windows 8.1. This update contains the following improvements and fixes the following issues:

    Improvement 1

    The enrollment provisioning document supports intermediate certificates along with the device certificate and the root CA certificate. This update adds a management solution to provision a chain of more than two certificates onto the device.

    Improvement 2

    A new ResetUserPassword static method is added to the MDM_Client WMI class. This method is added to support a helpdesk-aided password reset scenario where the user of the device forgets the password. In this scenario, the administrator can push a known password to the device. The password must be sent to the user out of band of the management channel. When the user receives the known password and logs in to the device, they are forced to change the password.

    Improvement 3

    The MDM client supports an enrollment-on-behalf-of protocol, which allows a local administrator to enroll a standard user into management on the device.

    Issue 1

    The LockWorkstation static method in the MDM_Client Windows Management Instrumentation (WMI) class fails when it is called to lock a workstation.

    Issue 2

    The MDM client sends the first request to the management endpoint without providing the device client certificate. Then, the client looks for a specific error code, and reissues the request with the device client certificate included. However, certain server side Secure Sockets Layer (SSL) implementations cannot be configured to return the error code. Additionally, the client does not return the full certificate chain in the SSL handshake properly.

    After you install this update, a Transport Layer Security (TLS) mutual authentication session is properly negotiated.
