802.1x using client cert 1920 switch ports?

Hi,

Looking to setup some 1920G (i.e. Comware) switches to use 802.1X for switch port auth, with the connecting devices (thin clients) having device cetrificates installed for the auth exchange.

The backend is Microsoft NPS (radius) integrated into a Microsoft enterprise CA setup.

The HP manaual talks about an 'EAP Relay' mode of operation that "supports various EAP authentication methods"

But examples involve username/password type auth and nothing mentioned about client certs etc.

Has anyone got 802.1X switch port security on 1920G working for devices connecting with instlled client certs?

thanks,

Sez
