oracle server->freeradius->ssl->ldap

Oracle advanced security product supports external radius authentication. I would like to use this external auth for oracle clients connecting to an oracle db server. The radius server would need to talk to an external ldap over ssl. I've installed freeradius on the db server, but have no idea how to configure this. Can you please get me going. I am a complete novice. I'm sorry to ask such a uninformed question. Thanks.
