I'm very new to using FreeRadius and apologize I don't have a lot of technical knowledge about it. I am setting up FreeRadius with a WAP2-Enterprise wifi network, with the FreeRadius server configured from my Ubiquiti access points. I set up the sql module, and made sure "sql" was listed under the "authorize" and "session" sections of by site's (default) configuration. I also enabled accounting and everything seemed to be working. I added users to the radcheck table with cleartext passwords. I added a Simultaneous-Use line for my user, but it always seemed to be ignored. After a lot of searching, I've discovered that my 'default' config was being used for the 'outer' authentication (eap), and then the "inner-tunnel" config was being used for actual authentication. This already has the sql option under "authorize", but not in "session". Adding "sql" to the "session" section of /etc/freeradius/sites-enabled/inner-tunnel is what finally allowed Simultaneous-Use checking. I'm posting this because this didn't seem to be documented (here: https://www.freeradius.org/documentation/freeradius-server/3.2.9/howto/simul...). It would have been helpful to have a hint about the inner-tunnel configuration when using eap authentication. I'm not looking for more help at the moment, other than that I am wondering if there is a way to constrain simultaneous connections for all users at once. The Simultaneous-Use query doesn't look for a DEFAULT line in the mysql database. Matthew
