EAP-TTLS with LDAP and KRB5?

Hi all, using 1.1.7 (forgive me) I have EAP-TTLS working from the files module and I have krb5 athentication working with ldap authorization fro radtest, but when I try EAP-TTLS as an ldap user I fail to connect, and the sever never seems to try the krb5 module. Before I start pulling my hair out is even possible? http://lists.cistron.nl/pipermail/freeradius-users/2006-March/msg00055.html seems to suggest it is but my searches aren't turning up much specifics... Thanks, -Jon
