I've got the radius server up on a unix box and got it to authenticate
users off of a active directory and that part is working fine.
The problem now is that I'd like to have our linux pptp server (running
poptop) authenticate users via radius.
I've been able to get the pptp server make requests to the radius server
but the radius server fails and here are some logs.
I've seen a lot of posts on this group who claims that they have a setup
like this working but I've not seen a working config. File example.
Anyways, anyone have any idea?
