Good Day, I've an interesting question. I currently authenticate users via caller-id for a static ip delivery system. I have had to change the "sql_user_name" to the "calling-station-id" attribute so that i can match the entries to so called usernames in the MYSQL database This is working and works well as the username for authentication ends up being the caller id. I now have to authenticate users based on username and password in one instance and solely calling-station-id in another. the config i use in the "files" to authenticate a user on caller id is as follows: DEFAULT Calling-Station-ID =="1234567890", Auth-Type := Accept Framed-IP-Address = 155.22.0.21 DEFAULT Calling-Station-ID =="2234567890", Auth-Type := Accept Framed-IP-Address = 155.22.0.22 DEFAULT Calling-Station-ID =="3234567890", Auth-Type := Accept Framed-IP-Address = 155.22.0.23 DEFAULT Calling-Station-ID =="4234567890", Auth-Type := Accept Framed-IP-Address = 155.22.0.24 the DEFAULT section has the framing types etc set. How would i now do this in the MYSQL database as there is no way of tying the "username" to anything ? Regards John
