Thanks again with your answer. When you speak about "an external mechanism" to synchronize user data for authentication, this means that for example, I should to do a mysql replica with this table? I want to get to synchronize both concepts, authentication and accounting data because I want to get two servers with identical data and functionality in real time. So, I have it clear. I should to get to write accounting records into a detail file. I have tested it with radlogin client, in authentication mode and accounting mode and both works fine. Thanks for your answer again. I am going to begin with a original configuration files, with basic functionality and I'm going to work to get write accounting records in detail file.
