Data Types in RADIUS
Abstract
RADIUS specifications have used data types for two decades without
defining them as managed entities. During this time, RADIUS
implementations have named the data types and have used them in
attribute definitions. This document updates the specifications to
better follow established practice. We do this by naming the data
types defined in RFC 6158, which have been used since at least the
publication of RFC 2865. We provide an IANA registry for the data
types and update the "RADIUS Attribute Types" registry to include a
Data Type field for each attribute. Finally, we recommend that
authors of RADIUS specifications use these types in preference to
existing practice. This document updates RFCs 2865, 3162, 4072,
6158, 6572, and 7268.
