[pap] WARNING! No "known good" password found for the user.

[yata]

HI, I'm really new of freeradius.

I wanna use freeradius as a radius server and dhcp server.
When I try to connect to radius server from pppoe client(windwos vista
laptop)  via ERX310(juniper),  freeradius shows following error messages. I
have no clue what's wrong. I'm really confused.
Message said no post-auth type found. But man page said it should not be
set.
How can I resolve this problem ?
Any advice will help me!
