See the INSTALL file, in the parent directory.
For every file there is a fully commented example file included, that explains what is does, and how to use it. Read those sample files too!
Again, many of the configuration files are ONLY documented in the comments included in the files. Reading the configuration files is required to fully understand how to create complex configurations of the server.
See the raddb/radiusd.conf file for the base configuration file.
The latest version of FreeRADIUS is always available from the git repository hosted on GitHub at
https://github.com/FreeRADIUS/freeradius-server
There are two mailing lists for users and developers. General user, administrator and configuration issues should be discussed on the users list at:
http://lists.freeradius.org/mailman/listinfo/freeradius-users
When asking for help on the users list, be sure the include a detailed and clear description of the problem, together with full debug output from FreeRADIUS, obtained by running
$ radiusd -X
Developers only discussion is to be had on the developers list:
http://lists.freeradius.org/mailman/listinfo/freeradius-devel
Please do not raise general configuration issues there.

If you have ANY problems, concerns, or surprises when running the server, then run it in debugging mode, as root, from the command line:
$ radiusd -X
It will produce a large number of messages. The answers to many questions, and the solution to many problems, can usually be found in these messages.
