Thanks Alan DeKok, but I have some questions.

So, how I said in the last post, the HOW_TO about SQL is out-of-date. The tables has name/schema changed. But I will have success.

All of this is documented in the config files. I search in the config files but I don't find nothing about this changes. In the sql directory have only the schemas to databases, and in the sql.conf file have only the configurations to access the database. See raddb/sites-available/dhcp, and modules/mac2ip Don't have problems in use this options? I read that it is in experimental stage. I think that this can break my server. No more, thanks Inácio Alves http://www.polluxweb.com/inacioalves/site
