NPS: Check for VSAs in RADIUS Access-Request packet

Hello,

is it possible check for vendor specific attributes which are in the RADIUS Access-Request packet?

For example, I want to define a network policy where in the condition the existence of a vsa will be checked (Aruba-Essid-Name, vendor 14823) and only if this exists network acces will be granted if configured constraints are met. I searched for this in conditions but only found the ability to return standard or vendor specific attributes (settings). I know this is possible in FreeRADIUS.

Thank in advance,

Tobias Hachmer
