Re: [Emu] EAP, RADIUS, UTF-8, RFC 4282 and SASLPREP: the interop nightmare

["Josh Howlett" <Josh.Howlett at ja.net>]

FWIW, Kerberos has a similar problem (with different but similarly
obscure origins); see Section 5.2.1 of RFC4120 for some background. The
Kerberos WG is currently chartered to fix this, but there's not been
much movement yet AFAIK.

It occurred that to me that EAP & Kerberos implementors might appreciate
a common approach to both problems, if that were feasible. The techs are
obviously very different, but within implementations their respective
moving parts require careful choreography to provide users with a good
experience.
