RFC 2882 is certainly a fact-based document. It reports existing
deployment behaviors. Its abstract reads:
Abstract
This document describes current practices implemented in NAS products
that go beyond the scope of the RADIUS RFCs 2138, 2139 [1,2]. The
purpose of this effort is to give examples that show the need for
addressing and standardizing these types of ad-hoc functions. Since
many of these features require a matching server support component,
the ability to deploy and manage interoperable NAS and AAA server
products is severely hindered.
These practices are documented here to show functions that are
obviously desired in developing future AAA protocols for NAS
deployment.
IMHO, we should be careful about inferring any desired or implied level
of standardization of any of the practices reported in 2882. If there
is no good reason to the contrary, then following existing convention
may be a good thing. OTOH, the fact that one or more vendors chose to
implement a needed (or desired) function in a particular fashion should
not set a binding precedent on the RADEXT WG. These extensions, in all
likelihood, received no IETF review, or even third party review, prior
to their implementation and deployment. We should look at these "ad
hoc" extensions with a critical eye.
