If I set the use Radius to accounting in the DHCP server option the clients get an IP without authenticating from the radius first.
When I have it to YES (not accounting) new clients get an Access-Reject and don’t get an IP. radpostauth table of the Radius gets rejected entries.
The moment I change it to Accounting the same client gets an IP and gets registered in the radacct table of the RADIUS but nothing on the radpostauth when I believe it shouldn’t authenticate and get an IP
