ppp and radius authentication

[Robert Blacquiere]

Hi,

I'm working on a system giving access with pptp to our network. 
I'd like to move the users from the /etc/ppp/ppp.sercet and have
them in a radius server. I have build a test setup but it fails 
the authentication using radius. If i debug it seems ppp sends 
a radius paket without a username and passwd (with pap). The
radius server will reject this. Is there something missing? 
or have i overlooked some thing. With /etc/ppp/ppp.secret it works
normaly as expected. 

I use the ppp option set radius /etc/radius.conf 
and have there 2 lines in.

auth my_radius.server my_big_secret
acct my_radius.server my_big_secret

Also i did some tcpdumps to see if the radius server is missing the 
usernames. but when analysing the dump it is a empty username.

Robert
