Time for action – activating the NULL realm

Follow these steps to activate the NULL realm:

1. Edit the proxy.conf file under the FreeRADIUS configuration directory and change the following part from:

   #realm NULL {
   #       authhost        = radius.company.com:1600
   #       accthost        = radius.company.com:1601
   #       secret          = testing123
   #}

   to:

   realm NULL {
   #       authhost        = radius.company.com:1600
   #       accthost        = radius.company.com:1601
   #       secret          = testing123
   }

2. Restart the FreeRADIUS server in debug mode and authenticate as alice. Observe the output of the FreeRADIUS server. The following should be part of the output:

   [suffix] No '@' in User-Name = "alice", looking up realm NULL
   [suffix] Found realm "NULL"
   [suffix] Adding Stripped-User-Name = "alice"
   [suffix] Adding Realm = "NULL"
   [suffix] Authentication realm is LOCAL.
   ++[suffix] returns ok
