#
#	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.

#	In 1.x, the "authorize", etc. sections were global in

#	section.  It is used when no server name is specified.

#	We don't indent the rest of this file, because doing so

#  then realms, and finally look in the "users" file.
#
#  Any changes made here should also be made to the "inner-tunnel"
#  virtual server.

#  The order of the realm modules will determine the order that
#  we try to find a matching realm.
#
#  Make *sure* that 'preprocess' comes before any realm if you 
#  need to setup hints for the remote radius server

	#  attribute for authentication, the mschap module will find

#
#
#  This section lists which modules are available for authentication.
#  Note that it does NOT mean 'try each module in order'.  It means
#  that a module from the 'authorize' section adds a configuration
#  attribute 'Auth-Type := FOO'.  That authentication type is then
#  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"
#  section.  Put them in the "post-auth" section instead.  That's what
#  the post-auth section is for.

#  counter module:
#  This module takes an attribute (count-attribute).
#  It also takes a key, and creates a counter for each unique
#  key.  The count is incremented when accounting packets are
#  received by the server.  The value of the increment depends
#  on the attribute type.
#  If the attribute is Acct-Session-Time or of an integer type we add
#  the value of the attribute. If it is anything else we increase the
#  counter by one.
#
#  The 'reset' parameter defines when the counters are all reset to
#  zero.  It can be hourly, daily, weekly, monthly or never.
#
#  hourly: Reset on 00:00 of every hour
#  daily: Reset on 00:00:00 every day
#  weekly: Reset on 00:00:00 on sunday
#  monthly: Reset on 00:00:00 of the first day of each month
#
#  It can also be user defined. It should be of the form:
#  num[hdwm] where:
#  h: hours, d: days, w: weeks, m: months
#  If the letter is ommited days will be assumed. In example:
#  reset = 10h (reset every 10 hours)
#  reset = 12  (reset every 12 days)
#
#
#  The check-name attribute defines an attribute which will be
#  registered by the counter module and can be used to set the
#  maximum allowed value for the counter after which the user
#  is rejected.
#  Something like:
#
#  DEFAULT Max-Daily-Session := 36000
#          Fall-Through = 1
#
#  You should add the counter module in the instantiate
#  section so that it registers check-name before the files
#  module reads the users file.
#
#  If check-name is set and the user is to be rejected then we
#  send back a Reply-Message and we log a Failure-Message in
#  the radius.log
#
#  If the count attribute is Acct-Session-Time then on each
#  login we send back the remaining online time as a
#  Session-Timeout attribute ELSE and if the reply-name is
#  set, we send back that attribute.  The reply-name attribute
#  MUST be of an integer type.
#
#  The counter-name can also be used instead of using the check-name
#  like below:
#
#  DEFAULT  Daily-Session-Time > 3600, Auth-Type = Reject
#      Reply-Message = "You've used up more than one hour today"
#
#  The allowed-servicetype attribute can be used to only take
#  into account specific sessions. For example if a user first
#  logs in through a login menu and then selects ppp there will
#  be two sessions. One for Login-User and one for Framed-User
#  service type. We only need to take into account the second one.
#
#  The module should be added in the instantiate, authorize and
#  accounting sections.  Make sure that in the authorize
#  section it comes after any module which sets the
#  'check-name' attribute.

#  This means that LDAP servers don't understand EAP.  If you
#  force "Auth-Type = LDAP", and then send the server a
#  request containing EAP authentication, then authentication
#  WILL NOT WORK.
#
#  The solution is to use the default configuration, which does
#  work.
#
#  Setting "Auth-Type = LDAP" is ALMOST ALWAYS WRONG.  We
