+#
+#	There may be a lot of output, but look carefully for words like:
+#	"warning", "error", "reject", or "failure".  The messages there

+#
+#	If you are going to ask a question on the mailing list, then
+#	explain what you are trying to do, and include the output from
+#	debugging mode (radiusd -X).  Failure to do so means that all

+#   This should be automatically set at configuration time.
+#
+#   If the server builds and installs, but fails at execution time
+#   with an 'undefined symbol' error, then you can use the libdir
+#   directive to work around the problem.
+#
+#   The cause is usually that a library has been installed on your
+#   system in a place where the dynamic linker CANNOT find it.  When
+#   executing as root (or another user), your personal environment MAY
+#   be set up to allow the dynamic linker to find the library.  When
+#   executing as a daemon, FreeRADIUS MAY NOT have the same
+#   personalized configuration.
+#
+#   To work around the problem, find out which library contains that symbol,
+#   and add the directory containing that library to the end of 'libdir',
+#   with a colon separating the directory names.  NO spaces are allowed.
+#
+#   e.g. libdir = /usr/local/lib:/opt/package/lib
+#
+#   You can also try setting the LD_LIBRARY_PATH environment variable
+#   in a script which starts the server.
+#
+#   If that does not work, then you can re-configure and re-build the

+#
+#  The panic action is a command which will be executed if the server
+#  receives a fatal, non user generated signal, i.e. SIGSEGV, SIGBUS,
+#  SIGABRT or SIGFPE.
+#
+#  This can be used to start an interactive debugging session so

+#  - %p   The PID of the currently executing program e.g. 12345
+#
+#  Standard ${} substitutions are also allowed.
+#
+#  An example panic action for opening an interactive session in GDB would be:
+#
+#panic_action = "gdb %e %p"
+#
+#  Again, don't use that on a production system.
+#
+#  An example panic action for opening an automated session in GDB would be:
+#
+#panic_action = "gdb -silent -x ${raddbdir}/panic.gdb %e %p 2>&1 | tee ${logdir}/gdb-${name}-%p.log"

+#
+#  WARNING: If you notice that requests take a long time to be handled,
+#  then this MAY INDICATE a bug in the server, in one of the modules
+#  used to handle a request, OR in your local configuration.
+#
+#  This problem is most often seen when using an SQL database.  If it takes
+#  more than a second or two to receive an answer from the SQL database,
+#  then it probably means that you haven't indexed the database.  See your
+#  SQL server documentation for more information.

+#
+max_request_time = 30
+
+#  cleanup_delay: The time to wait (in seconds) before cleaning up
+#  a reply which was sent to the NAS.
+#
+#  The RADIUS request is normally cached internally for a short period
+#  of time, after the reply is sent to the NAS.  The reply packet may be
+#  lost in the network, and the NAS will not see it.  The NAS will then
+#  re-send the request, and the server will respond quickly with the
+#  cached reply.
+#
+#  If this value is set too low, then duplicate requests from the NAS
+#  MAY NOT be detected, and will instead be handled as separate requests.
+#
+#  If this value is set too high, then the server will cache too many
+#  requests, and some new requests may get blocked.  (See 'max_requests'.)
+#
+#  Useful range of values: 2 to 10
+#
+cleanup_delay = 5
+
+#  max_requests: The maximum number of requests which the server keeps
+#  track of.  This should be 256 multiplied by the number of clients.
+#  e.g. With 4 clients, this number should be 1024.
+#
+#  If this number is too low, then when the server becomes busy,
+#  it will not respond to any new requests, until the 'cleanup_delay'
+#  time has passed, and it has removed the old requests.
+#
+#  If this number is set too high, then the server will use a bit more
+#  memory for no real benefit.
+#
+#  If you aren't sure what it should be set to, it's better to set it
+#  too high than too low.  Setting it to 1000 per client is probably
+#  the highest it should be.

+#
+#  The default is 'off' because it would be overall better for the net
+#  if people had to knowingly turn this feature on, since enabling it
+#  means that each client request will result in AT LEAST one lookup
+#  request to the nameserver.   Enabling hostname_lookups will also
+#  mean that your server may stop randomly for 30 seconds from time
+#  to time, if the DNS requests take too long.
+#
+#  Turning hostname lookups off also means that the server won't block

+#
+#  There may be multiple methods of attacking on the server.  This
+#  section holds the configuration items which minimize the impact
+#  of those attacks
+#
+security {
+	#  chroot: directory where the server does "chroot".
+	#
+	#  The chroot is done very early in the process of starting
+	#  the server.  After the chroot has been performed it
+	#  switches to the "user" listed below (which MUST be
+	#  specified).  If "group" is specified, it switches to that
+	#  group, too.  Any other groups listed for the specified
+	#  "user" in "/etc/group" are also added as part of this
+	#  process.
+	#
+	#  The current working directory (chdir / cd) is left
+	#  *outside* of the chroot until all of the modules have been
+	#  initialized.  This allows the "raddb" directory to be left
+	#  outside of the chroot.  Once the modules have been
+	#  initialized, it does a "chdir" to ${logdir}.  This means
+	#  that it should be impossible to break out of the chroot.
+	#
+	#  If you are worried about security issues related to this
+	#  use of chdir, then simply ensure that the "raddb" directory
+	#  is inside of the chroot, end be sure to do "cd raddb"
+	#  BEFORE starting the server.
+	#
+	#  If the server is statically linked, then the only files
+	#  that have to exist in the chroot are ${run_dir} and
+	#  ${logdir}.  If you do the "cd raddb" as discussed above,
+	#  then the "raddb" directory has to be inside of the chroot
+	#  directory, too.

+#	chroot = /path/to/chroot/directory
+
+	# user/group: The name (or #number) of the user/group to run radiusd as.
+	#
+	#   If these are commented out, the server will run as the
+	#   user/group that started it.  In order to change to a
+	#   different user/group, you MUST be root ( or have root
+	#   privileges ) to start the server.
+	#
+	#   We STRONGLY recommend that you run the server with as few
+	#   permissions as possible.  That is, if you're not using
+	#   shadow passwords, the user and group items below should be
+	#   set to radius'.
+	#
+	#  NOTE that some kernels refuse to setgid(group) when the
+	#  value of (unsigned)group is above 60000; don't use group
+	#  "nobody" on these systems!
+	#
+	#  On systems with shadow passwords, you might have to set
+	#  'group = shadow' for the server to be able to read the
+	#  shadow password file.  If you can authenticate users while
+	#  in debug mode, but not in daemon mode, it may be that the
+	#  debugging mode server is running as a user that can read
+	#  the shadow info, and the user listed below can not.
+	#
+	#  The server will also try to use "initgroups" to read
+	#  /etc/groups.  It will join all groups where "user" is a
+	#  member.  This can allow for some finer-grained access
+	#  controls.

+	#  will be accepted.
+	#
+	#  If this number is set too high, then an attacker may be
+	#  able to send a small number of packets which will cause

+	#  accounting packets.
+	#
+	#  It's also useful when a NAS marks a RADIUS server "dead".

+# THREAD POOL CONFIGURATION
+#
+#  The thread pool is a long-lived group of threads which
+#  take turns (round-robin) handling any incoming requests.
+#
+#  You probably want to have a few spare threads around,
+#  so that high-load situations can be handled immediately.  If you
+#  don't have any spare threads, then the request handling will
+#  be delayed while a new thread is created, and added to the pool.
+#
+#  You probably don't want too many spare threads around,
+#  otherwise they'll be sitting there taking up resources, and
+#  not doing anything productive.

+	#  If this limit is ever reached, clients will be LOCKED OUT, so it
+	#  should NOT BE SET TOO LOW.  It is intended mainly as a brake to
+	#  keep a runaway server from taking the system with it as it spirals

+	#
+	#  You may find that the server is regularly reaching the
+	#  'max_servers' number of threads, and that increasing
+	#  'max_servers' doesn't seem to make much difference.
+	#
+	#  If this is the case, then the problem is MOST LIKELY that
+	#  your back-end databases are taking too long to respond, and
+	#  are preventing the server from responding in a timely manner.
+	#
+	#  The solution is NOT do keep increasing the 'max_servers'
+	#  value, but instead to fix the underlying cause of the

+	#  servers to handle transient load spikes.
+	#
+	#  It does this by periodically checking how many servers are
+	#  waiting for a request.  If there are fewer than

+	#  Each module has a configuration as follows:
+	#
+	#	name [ instance ] {
+	#		config_item = value
+	#		...
+	#	}
+	#
+	#  The 'name' is used to load the 'rlm_name' library
+	#  which implements the functionality of the module.
+	#
+	#  The 'instance' is optional.  To have two different instances
+	#  of a module, it first must be referred to by 'name'.
+	#  The different copies of the module are then created by
+	#  inventing two 'instance' names, e.g. 'instance1' and 'instance2'
+	#
+	#  The instance names can then be used in later configuration
+	#  INSTEAD of the original 'name'.  See the 'radutmp' configuration
+	#  for an example.
+	#
+
+	#
+	#  As of 3.0, modules are in mods-enabled/.  Files matching
+	#  the regex /[a-zA-Z0-9_.]+/ are loaded.  The modules are
+	#  initialized ONLY if they are referenced in a processing
+	#  section, such as authorize, authenticate, accounting,
+	#  pre/post-proxy, etc.

+# Instantiation
+#
+#  This section orders the loading of the modules.  Modules
+#  listed here will get loaded BEFORE the later sections like
+#  authorize, authenticate, etc. get examined.
+#
+#  This section is not strictly needed.  When a section like
+#  authorize refers to a module, it's automatically loaded and
+#  initialized.  However, some modules may not be listed in any
+#  of the following sections, so they can be listed here.
+#
+#  Also, listing modules here ensures that you have control over
+#  the order in which they are initialized.  If one module needs
+#  something defined by another module, you can list them in order
+#  here, and ensure that the configuration will be OK.
+#
+#  After the modules listed here have been loaded, all of the modules
+#  in the "mods-enabled" directory will be loaded.  Loading the
+#  "mods-enabled" directory means that unlike Version 2, you usually
+#  don't need to list modules here.
+#
+instantiate {
+	#
+	# We list the counter module here so that it registers
+	# the check_name attribute before any module which sets
+	# it
+#	daily
+
+	# subsections here can be thought of as "virtual" modules.
+	#
+	# e.g. If you have two redundant SQL servers, and you want to
+	# use them in the authorize and accounting sections, you could
+	# place a "redundant" block in each section, containing the
+	# exact same text.  Or, you could uncomment the following
+	# lines, and list "redundant_sql" in the authorize and
+	# accounting sections.
+	#
+	#redundant redundant_sql {
+	#	sql1
+	#	sql2
+	#}

+#  Policies are virtual modules, similar to those defined in the
+#  "instantiate" section above.
+#
+#  Defining a policy in one of the policy.d files means that it can be
+#  referenced in multiple places as a *name*, rather than as a series of
+#  conditions to match, and actions to take.
+#
+#  Policies are something like subroutines in a normal language, but
+#  they cannot be called recursively. They MUST be defined in order.
+#  If policy A calls policy B, then B MUST be defined before A.
