Dear All,
I need your help to configure FreeRadius to rewrite the User-Name 
attribute in Accounting-Request.
my setup as follow; please correct me if i had a mistake,
i'm using Freeradius to do a proxy to another radius server. we are 
using one username (wanadoo) as a default username for our prepaid card 
in the freeradius server we replace the username with a new one which is 
the same as the password, so we are using pre-proxy to call attr_rewrite 
that will replace the username with the  new one. As an authintecation 
process every thing goes will, but for the Accounting the free radius 
didnt change the username and send it as it is to the another radius 
which mean that i couldnt do accounting for them. so could you please 
help me to solve like this problem.

attr_rewrite fixusername {
                attribute = User-Name
                searchin = proxy
                searchfor ="wanadoo"
                replacewith = %{Password}
                ignore_case = no
                new_attribute = no
                max_matches = 10
                append = no

pre-proxy {
This is what i found in the log file,

Packet-Type = Access-Request

        User-Name = "11111111114242"

        NAS-IP-Address =
        Client-IP-Address =
        Stripped-User-Name = "wanadoo"
        Realm = "coolnet"
        Realm = "coolnet"
        Proxy-State = 0x3833

        User-Name = "wanadoo"
        NAS-Port = 2
        Service-Type = Framed-User
        Framed-Protocol = PPP
        Framed-IP-Address =

        NAS-IP-Address =
        Client-IP-Address =
        Acct-Unique-Session-Id = "26331f725bfc7b96"
        Stripped-User-Name = "wanadoo"
        Realm = "coolnet"
