The Remote Authentication Dial In User Service (RADIUS) protocol is nearing exhaustion of its current 8-bit attribute type space. In addition, experience shows a growing need for complex grouping, along with attributes which can carry more than 253 octets of data. This document defines changes to RADIUS which address all of the above problems.
