>How can i instruct to the database that i will use chap ? Don't. Just don't.
If you use default configuration and send pap request, server will process it as pap, if you send chap, it will process it as chap, if you send mschap it will process it as mschap, if you send eap ... Well you should be able to guess by now. There is *absolutely* nothing you need to configure to make it happen. It "just works". Ivan Kalik Kalik Informatika ISP - List info/subscribe/unsubscribe?
