FreeRadius2 & Krb

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.
