Extended Remote Authentication Dial In User Service (RADIUS) Attributes Extended Remote Authentication Dial In User Service (RADIUS) Attributes
draft-ietf-radext-extended-attributes-08.txt draft-ietf-radext-extended-attributes-09.txt
Abstract
For the Remote Authentication Dial In User Service (RADIUS) protocol
to continue to support new applications, the RADIUS attribute type
space must be extended beyond the current limit of 255 possible
attribute types while maintaining backwards compatibility with the
existing protocol. This document defines a mechanism to accomplish
that task, along with standard methods to group together related
attributes and to encode values that don't fit into 253 octets.
