Remote Authentication Dial-In User Service (RADIUS)
Protocol Extensions
Abstract
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 that can carry more than 253 octets of data. This
document defines changes to RADIUS that address all of the above
problems.
