When using our RADIUS Server Instance there are only 20 slots in the configuration tool's UI. Here is how to add more client IPs and secrets.
While the UI in the configuration tool only shows 20 slots, the system will support more IPs/secrets in the client IP allow list. You can edit the config.xml file found in the c:\programdata\surepassid\ folder to add more clients.
Make a backup copy of the file first, to be safe, then add more client blocks in this section of the config.xml:
<?xml version="1.0" encoding="utf-8"?>
