RADIUS
, or Remote Authentication Dial-In User Service, is a widely-deployed
protocol that enables companies to authenticate, authorize and account for remote
users who want access to a system or service from a central network server.
RADIUS server validates your proof and also carries on the authorization. So the
RADIUS server received by ISA server responded (point out the customer carries proof
to be not granted) and it means that the RADIUS server did not authorize you to carry.
Even if the proof has already passed an identify verification, the ISA server may also
refuse you to carry a claim according to the authorization strategy of the RADIUS
server.
The principle of the RADIUS server is shown in the following pictures:
