Thanks Santiago and Ivan, The schema of the database is in the source of instalation and I have create my database in MySQL. I think that lack documentation to work with freeRADIUS. The new version 2.x is very different from early 1.x. So, how I said in the last post, the HOW_TO about SQL is out-of-date.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. Finally. About the DHCP: How I said, my AP ignores the configurations that I set on users file, even if I disable the DHCP server in the AP. If I configure a DHCP server on my freeRADIUS server, I need atach MACxIP or if I set the configurations in the users file this informations will to the client? Again thanks to all, Inácio Alves http://www.polluxweb.com/inacioalves/site
