+#	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.
+#
+#	If you are using 802.1X (EAP) authentication, please see also
+#	the "inner-tunnel" virtual server.  You wll likely have to edit
+#	that, too, for authentication to work.
+#
+#	$Id$
+#
+######################################################################
+#
+#	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.

+#  This section lists which modules are available for authentication.

+#  used to pick the apropriate module from the list below.
+#
+
+#  In general, you SHOULD NOT set the Auth-Type attribute.  The server
+#  will figure it out on its own, and will do the right thing.  The
+#  most common side effect of erroneously setting the Auth-Type
+#  attribute is that one authentication method will work, but the
+#  others will not.
+#
+#  The common reasons to set the Auth-Type attribute by hand
+#  is to either forcibly reject the user (Auth-Type := Reject),
+#  or to or forcibly accept the user (Auth-Type := Accept).
+#
+#  Note that Auth-Type := Accept will NOT work with EAP.
+#
+#  Please do not put "unlang" configurations into the "authenticate"
