HP MSM750 Access Controller and Windows Server Ent 2008


I'm running into a problem with the HP MSM750 Access Controller and Windows Server Ent 2008. I have configured the access controller as a radius client in NPS services on Windows Server Ent 2008; at this point the controller communicates to the radius server and the radius connects to the controller. Now when configuring a workstation to authenticate through the access controller I receive the following event in the event log on the radius server.

While working with HP on this issue we have found the fix for this problem. Also here is the case number to reference the problem 4600138448.

The NPS server or server's need to have Active Directory Certificate Services installed and configured for certificate autoenrollment. Once configured users authenticate correctly.

Microsoft Server Certificate Deployment

Microsoft Deploying 802.1X Authenticated
Wireless Access with PEAP-MS-CHAP v2
