reply_log issue

[Mark Jones]

I have turned on reply_log option in the post-auth area. for both accepted 
and rejected packets.

It is logging to the file successfully but it does not log the username or 
password.

        Packet-Type = Access-Accept
        Framed-Address = x.x.x.x
        Framed-Netmask = 255.255.255.255
        Port-Limit = 1
        Framed-Protocol = PPP
        User-Service-Type = Framed-User
        Framed-MTU = 1492
        Framed-Routing = None

Any ideas?
