Appendix B: RADIUS server configuration
RADI US serve r conf igura tion
This appendix outlines how to set up a RADIUS server for user authentication.
B.1  RADIUS server configuration
The following procedure is an example of how to set up a simple RADIUS server. You install the RADIUS server software on 
a separate computer. In this example, we use FreeRADIUS third-party software.
1. Download and install FreeRADIUS from www.freeradius.net
 as the RADIUS server. This is a Windows 32-bit installation 
that is known to work. If you try another third-party tool and it does not work, use the FreeRADIUS software from 
freeradius.net.
2. Open the radius.conf file in the <Path_to_Radius>\etc\raddb folder, locate the "bind_address" field, and enter your 
RADIUS server IP address. An example is
bind_address = 10.14.61.109
Text editor software that supports direct editing and saving of UNIX text encodings and line breaks, such as EditPad 
Lite, is needed for this editing.
3. In the users.conf file in the <Path_to_Radius>\etc\raddb folder, add the following text to configure a user "Tester" with 
an Administrator role.
Tester               User-Password == "testpw"
        GE-PDC-USER-Role = Administrator,
4. In the clients.conf file in the <Path_to_Radius>\etc\raddb folder, add the following text to define the UR as a RADIUS 
client, where the client IP address is 10.0.0.2, the subnet mask is 255.255.255.0, the shared secret specified here is also 
configured on the UR device for successful authentication, and the shortname is a short, optional alias that can be 
used in place of the IP address.
client 10.0.0.2/24 {
secret = testing123
shortname = private-network-1
}
5. In the <Path_to_Radius>\etc\raddb folder, create a file called dictionary.ge and add the following content.
