I'm trying to get FreeRadius2 to authenicate with MIT Kerberos.  When radius enters kerberos, it dies with no message.  Any suggestions on where to look for clues?

OS: FreeBSD 9
Radius: FreeRadius 2.1.12
Kerberos:  MIT Kbr5 1.9.2

I'm not seeing obvious errors in Debug output.

[pap] WARNING! No "known good" password found for the user. Authentication may fail because of this.
++[pap] returns noop
Found Auth-Type = Kerberos
# Executing group from file /usr/local/etc/raddb/sites-enabled/default
+- entering group Kerberos {...}


I have experience configuring FreeRadius the original but was hoping to move to 2.
