Ah... the NAS isn't defined globally, so it isn't being used.

In theory, yes. The issue (IIRC) is that the client is either tied to
a virtual server, or to a specific "listen" section. The API used by
checkrad hasn't been updated to handle some of the new features, so the
client isn't being found.
Part of the issue is that in 2.0, the client can be defined *multiple*
times, with *different* shared secrets. It can be difficult to say
which one to use.
If it's OK to find the client that is tied to the virtual server, that
should be possible.
