Strange password when authenticating via pppoe-server.

[Maciej Drobniuch]

Hi!
Now I have a new problem.
When auth via radiusclient, everyting works fine:

>radtest steve testing localhost 1813 somesecret

Sat Jul 12 12:07:31 2008 : Debug:   modsingle[authenticate]: calling pap
(rlm_pap) for request 4

        Framed-IP-Netmask = 255.255.255.0
        Framed-Routing = Broadcast-Listen
        Framed-Filter-Id = "std.ppp"
        Framed-MTU = 1500
        Framed-Compression = Van-Jacobson-TCP-IP

I've also tried to auth using this command(and the login is also
successful):
echo User-Name = "steve", CHAP-Password = "testing" | radclient localhost
auth somesecret

But when i've had tried to login from a client (windows xp) station using
the pppoe-server(on the server) the debug output looks like this:
