I'm running FreeRADIUS 3 on Red Hat Linux with a MySQL backend. I want FreeRADIUS to only read from the database-no writes-since I'm syncing it to another server for redundancy and using a separate interface to manage user accounts.

Everything works, but I see Access-Accept and Access-Reject entries being written to radpostauth. How can I stop this?

Edit the configuration files. They're text. If you want to know what to edit, run the server in debug mode. It will print out what it's doing, and why. Then, edit the relevant portion of the config files. Or, read the postauth section. It isn't large. Alan DeKok.
