Hi, I have a problem while autorizing with chap password....

Problem is next:
I have Allied Telesys NAS, it sends User-Name, CHAP Password and NAS IP, radius does everything ok,

but when it comes to part where he compares password it says: "Wrong password"...

I was debugging with -X -xx, and FR resolves password OK. It gets password from MySql database...

Why am I asking for help is next:

When I use radiusTest software from windows machine, send same data as NAS sends, authorisation goes OK...

Please help, how can I set it up to work for me....
