When using the FAST OTP preauthentication module for the KDC, the OTP is passed 
to the KDC over an encrypted FAST channel. The KDC then passes the OTP over to 
a RADIUS server.

When the KDC communicates with a RADIUS server, can this be done over a more 
secure method such as EAP or PEAP?

When OTP was first implemented in version 1.12, support for EAP was not 
included as stated here http://k5wiki.kerberos.org/wiki/Projects/OTPOverRADIUS 
: "RADIUS is not FIPS compliant due to the use of MD5 in the protocol. EAP 
might make RADIUS FIPS compliant and Fedora ships a libeap. Integration of EAP 
is not planned at this time".

Has integration of EAP been included in more recent versions? If not, is there 
any plan to?

Thanks,

Luke
