problem in integeration with poptop

[hadi golestani]

hi,
I've installed poptop and freeradius well and both are working,
but when I try to connect from a vpn connection or even radtest some error
occured.
what I need to add to users.conf for a simple radtest connection or a vpn
client?

it's the output of debug mode for vpn client, some thing like this has been
printed for radtest also:
