Configure free radius to blacklist instead of whitelist
Hi all, Is it possible to change the behavior of freeradius so that all users are allowed by default but then any users added to the db are then blocked?

Yes. How? It depends on how you're using the DB. Perhaps you could explain a bit more. How did you configure the DB? Did you use the "sql" module? Did you use the normal SQL schema? Do you have something else in the DB? Questions with minimal technical content get answers with minimal technical content. Alan DeKok.
Totally understand. Right now it's a very basic default install. CentOS 7 yum install freeradius freeradius-utils freeradius-mysql freeradius-perl -y Then opened up firewall ports and configured radiusd to start at boot. Besides that nothing else is changed I would like to configure it to have mysql host the db. I didn't do too much as I wanted to make sure this was possible first.

Yes, it's possible. Alan DeKok.
Awesome, thanks! How would I do that? I've googled quite a bit but haven't found anything. I've also looked in the config files but haven't found anything obvious. Though I could have missed it. The mysql part I can probable figure out. But changing the service to "allow all", then block the users in the db is the part I'd love some help with. Thanks!

There's no documentation which says "do what I want". The documentation describes how the server works, and how to configure it. Putting the pieces together is usually up to the reader.
The mysql part I can probable figure out. But changing the service to "allow all", then block the users in the db is the part I'd love some help with.
In sites-enabled/default, do the normal SQL lookup. Then accept them if not found, and reject them if found. authorize { ... sql if (notfound) { accept } else { reject } Alan DeKok.
I'll give this a shot. Thanks! On Mon, Apr 8, 2019 at 2:14 PM Alan DeKok <aland@deployingradius.com> wrote:
