Freeradius + EAP TLS + MySQL + PPTP

Hi, I want to setup a PPTP server with EAP TLS and authentication by FreeRadius. I've seen in a documentation that we must set Auth-type, but the documentation is out-dated and on freeradius.org, it's specified that Auth-type shouldn't be set manually. So, I don't know which data I must set in which table, MySQL-side. Can anyone help me ? Thanks, Regards, Grégoire Leroy
