Pass-through radius authentication in contrib's passwd module(radius.c) does not
include either a NAS-IP or a NAS-Identifier, according to radius RFC 2865 one of
these attributes is mandatory in the access request.

The thing is that the previous version of Radius RFC standard(RFC 2138)
specified that the access request "SHOULD" contain either a NAS-IP or a
NAS-Identifier but the current version use "MUST" instead.
