Hi, I have to follow this tutorial to get the the session limit working. But looking at the debug output it seems the sql counter is not executed. No Session-Timeout is sent to NAS as well. Accounting is working fine. I can see all the accounting information radacct time. Here is my configuration. Please let me know if I should provide more information.
