Hi all !! I have been running Freeradius fro a while now ( Ver 1.0.1 ) and so far I have been using the "users" file. To be able to use dilaup-admin interface so that people with no linux experience can maintain the system, I had to switch to the mysql-database. I generated teh schema with the db_sql_mysql.sql script that comes with freeradius. I have everything running fine. I can authenticate using radtest. I can even authenticate from some of my clients. The problem: Until now, I have had all my clients authenticate using blank usernames and passwords. a Lot of logistics involved in changing the clients in the field. I realise I cannot create a user via dialup-admin with a blank username. Is there a way to use the Calling-Station-ID to authenticate ? Because essentially this is what happened when using the users-file. I tried to play around with the settings: e.g. by setting username,password non-blank but making AUTH-TYPE = ACCEPT. and setting the Calling-Station-ID the expected value. But this is not working. Can someone help with a pointer ? I went through the archives but couldn't find someone that struggled with the same question ?!?!? Thanks and best ! John
