Hello. Is it possible to pair users with clients? I wan't to authenticate users on one RADIUS server for different services and "set up permissions", that certain client (that the user is connecting to) can only authenticate users for example with certain Auth-Type, so it will not be possible to access the service using different Auth-Type users (but with the same username). Is that doable?

In 2.0.5, you can tie virtual servers to clients. See raddb/sites-enabled/README Alan DeKok.
