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 system. 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 { fixusername pre_proxy_log } This is what i found in the log file, Packet-Type = Access-Request Wed Jan 31 07:55:27 2007 User-Name = "11111111114242" User-Password = "11111111114242" NAS-IP-Address = 172.16.5.188 Client-IP-Address = 172.16.5.188 Stripped-User-Name = "wanadoo" Realm = "coolnet" Realm = "coolnet" Proxy-State = 0x3833 Packet-Type = Accounting-Request Wed Jan 31 07:55:27 2007 Acct-Session-Id = "76" Acct-Status-Type = Start User-Name = "wanadoo" NAS-Port = 2 Service-Type = Framed-User Framed-Protocol = PPP Framed-IP-Address = 255.255.255.254 Class = 0x5376633d32 NAS-IP-Address = 172.16.5.188 Client-IP-Address = 172.16.5.188 Acct-Unique-Session-Id = "26331f725bfc7b96" Stripped-User-Name = "wanadoo" Realm = "coolnet" Realm = "coolnet" Proxy-State = 0x3834
