SYMPTOMS

Consider the following scenario:
  • You have a computer that is running Windows 7 or Windows Server 2008 R2.
  • Users connect the computer to a Cisco VPN server through a virtual private network (VPN) connection that is based on the Internet Key Exchange version 2 (IKEv2) protocol.
  • You configure the Cisco VPN server to forward authentication requests to a specified Remote Authentication Dial-in User Service (RADIUS) server.

    Note The RADIUS server is usually known as the Authentication Authorization Accounting server.
In this scenario, the VPN server cannot provide differential services according to the identity of the connected user. For example, some differential services include Virtual Routing and Forwarding (VRF), applications of QoS policy, and specific Firewall rules.

CAUSE

This issue occurs because the VPN client only sends the client IP address in the Identification payload field of the IKEv2 message. However, the Cisco VPN server expects the Identification payload field also to contain user name and domain name information. This behavior prevents the Cisco VPN server from forwarding an authentication request to the corresponding RADIUS server. Therefore, unexpectedly, the VPN server cannot group connected users.

RESOLUTION

Windows 7 and Windows Server 2008 R2 file information notes
Important Windows 7 hotfixes and Windows Server 2008 R2 hotfixes are included in the same packages. However, hotfixes on the Hotfix Request page are listed under both operating systems. To request the hotfix package that applies to one or both operating systems, select the hotfix that is listed under "Windows 7/Windows Server 2008 R2" on the page. Always refer to the "Applies To" section in articles to determine the actual operating system that each hotfix applies to.
  • The MANIFEST files (.manifest) and the MUM files (.mum) that are installed for each environment are listed separately in the "Additional file information for Windows Server 2008 R2 and for Windows 7" section. MUM and MANIFEST files, and the associated security catalog (.cat) files, are extremely important to maintaining the state of the updated component. The security catalog files, for which the attributes are not listed, are signed with a Microsoft digital signature.
