Chapter 12. Roaming and Proxying
The RADIUS protocol was designed with expandability in mind. If your initial RADIUS deployment only makes use of a local user store it is still possible to join a larger network of RADIUS servers without major changes to the configuration. The focus of this chapter is to help you integrate with other RADIUS servers.
In this chapter we shall:
- Discover the advantages and dangers of roaming
- See what a realm is and how it works in FreeRADIUS
- See how to proxy requests based on realms
- Explore ways to make a proxy setup more robust
So let's get on with it...
