#
#	As of 2.0.0, FreeRADIUS supports virtual hosts using the
#	\"server\" section, and configuration directives.
#
#	Virtual hosts should be put into the \"sites-available\"
#	directory.  Soft links should be created in the \"sites-enabled\"
#	directory to these files.  This is done in a normal installation.
#
#
######################################################################
#
#	Read \"man radiusd\" before editing this file.  See the section
#	titled DEBUGGING.  It outlines a method where you can quickly
#	obtain the configuration you want, without running into
#	trouble.  See also \"man unlang\", which documents the format
#	of this file.
#
#	This configuration is designed to work in the widest possible
#	set of circumstances, with the widest possible number of
#	authentication methods.  This means that in general, you should
#	need to make very few changes to this file.
#
#	The best way to configure the server for your local system
#	is to CAREFULLY edit this file.  Most attempts to make large
#	edits to this file will BREAK THE SERVER.  Any edits should
#	be small, and tested by running the server with \"radiusd -X\".
#	Once the edits have been verified to work, save a copy of these
#	configuration files somewhere.  (e.g. as a \"tar\" file).  Then,
#	make more edits, and test, as above.
#
#	There are many \"commented out\" references to modules such
#	as ldap, sql, etc.  These references serve as place-holders.
#	If you need the functionality of that module, then configure
#	it in radiusd.conf, and un-comment the references to it in
#	this file.  In most cases, those small changes will result
#	in the server being able to connect to the DB, and to
#	authenticate users.
#
######################################################################
 
#
#	In 1.x, the \"authorize\", etc. sections were global in
#	radiusd.conf.  As of 2.0, they SHOULD be in a server section.
#
#	The server section with no virtual server name is the \"default\"
#	section.  It is used when no server name is specified.
#
#	We don't indent the rest of this file, because doing so
#	would make it harder to read.

#  Authorization. First preprocess (hints and huntgroups files),
#  then realms, and finally look in the \"users\" file.
