Hello, I'm running Freeradius : freeradius: FreeRADIUS Version 2.2.8, for host x86_64-pc-linux-gnu, built on Apr 5 2016 at 13:40:43 I've configurated Active Directory integration, and it's working fine for authentication. Local users in users file are also ok. In the local users file I can specify a calling station id like : customer Cleartext-Password := "password",Calling-Station-Id == "AA-AA-AA-AA-AA-AA" How can I use a local file (or sql table) to link a user authenticated in Active Directory with one or several calling-station-id ? If possible I'd really prefer not to use the ActiveDirectory to store the Mac addresses. The goal is to limit each login to a few devices (I know it's possible to mask mac address, this is not the point here). I've tried to insert in the users file : customer2 Calling-Station-Id := "BB-BB-BB-BB-BB-BB" but with correct password customer2 is always authenticated using the BB-....-BB mac adress or not. Thks a lot for any help, Ethariel
