  Yes, but that adds server complexity, etc.

  Yup.  If you want to know if an SQL server is up, there are existing
tools to test that.  Personally, I would test:

  a) RADIUS via Status-Server
  b) SQL via sql client
  c) "test" user via Access-Request

  If you just do (c), you have no idea if the problem is the RADIUS
server or the SQL server.  Not that it matters to a NAS, of course, but
it matters to an administrator.
