Subject: help on pppd chap authorize by freeradius



Hi,
I encounter an chap authorization problem using pppoe3.8, ppp 2.4.4b1 and Freeradius 1.1.3. 
The relevant logs are:

Altough I can obtain authorization using:

       Framed-MTU = 1492
       Framed-Protocol = PPP
       Port-Limit = 1

Do anyone encounter the same problem?

I can add that chap fails with all ppp versions (>=2.4.2)
Thank you,

Alex
