# Microsoft CHAP authentication
#
#  This module supports MS-CHAP and MS-CHAPv2 authentication.
#  It also enforces the SMB-Account-Ctrl attribute.
#
mschap {
	#
	#  If you are using /etc/smbpasswd, see the 'passwd'
	#  module for an example of how to use /etc/smbpasswd

	# if use_mppe is not set to no mschap will
	# add MS-CHAP-MPPE-Keys for MS-CHAPv1 and
	# MS-MPPE-Recv-Key/MS-MPPE-Send-Key for MS-CHAPv2
	#
#	use_mppe = no

	# if mppe is enabled require_encryption makes
	# encryption moderate
	#
#	require_encryption = yes

	# require_strong always requires 128 bit key
	# encryption
	#
#	require_strong = yes

	# The module can perform authentication itself, OR
	# use a Windows Domain Controller.  This configuration
	# directive tells the module to call the ntlm_auth
	# program, which will do the authentication, and return
	# the NT-Key.  Note that you MUST have "winbindd" and
	# "nmbd" running on the local machine for ntlm_auth
	# to work.  See the ntlm_auth program documentation
	# for details.
	#
	# If ntlm_auth is configured below, then the mschap
	# module will call ntlm_auth for every MS-CHAP
	# authentication request.  If there is a cleartext
	# or NT hashed password available, you can set
	# "MS-CHAP-Use-NTLM-Auth := No" in the control items,
	# and the mschap module will do the authentication itself,
	# without calling ntlm_auth.
	#
	# Be VERY careful when editing the following line!
	#
	# You can also try setting the user name as:
	#
	#	... --username=%{mschap:User-Name} ...
	#
	# In that case, the mschap module will look at the User-Name
	# attribute, and do prefix/suffix checks in order to obtain
	# the "best" user name for the request.
	#

	# The default is to wait 10 seconds for ntlm_auth to
	# complete.  This is a long time, and if it's taking that
	# long then you likely have other problems in your domain.
	# The length of time can be decreased with the following
	# option, which can save clients waiting if your ntlm_auth
	# usually finishes quicker. Range 1 to 10 seconds.
	#
#	ntlm_auth_timeout = 10

	# An alternative to using ntlm_auth is to connect to the
	# winbind daemon directly for authentication. This option
	# is likely to be faster and may be useful on busy systems,
	# but is less well tested.
	#
	# Using this option requires libwbclient from Samba 4.2.1
	# or later to be installed. Make sure that ntlm_auth above is
	# commented out.

	# When using single sign-on with a winbind connection and the
	# client uses a different casing for the username than the
	# casing is according to the backend, reauth may fail because
	# of some Windows internals. This switch tries to find the

		#  Maximum number of connections
		#
		#  If these connections are all in use and a new one
		#  is requested, the request will NOT get a connection.
		#
		#  Setting 'max' to LESS than the number of threads means
		#  that some threads may starve, and you will see errors
		#  like 'No connections available and at max connection limit'
		#
		#  Setting 'max' to MORE than the number of threads means
		#  that there are more connections than necessary.
		max = ${thread[pool].max_servers}

		#  Spare connections to be left idle
		#
		#  NOTE: Idle connections WILL be closed if "idle_timeout"
		#  is set.  This should be less than or equal to "max" above.

		#
		#  0 means "infinite"

		#  to open a connection, and fails.  During this time,
		#  no new connections will be opened.
		retry_delay = 30

		#  The lifetime (in seconds) of the connection
		#
		#  NOTE: A setting of 0 means infinite (no limit).
		lifetime = 86400

		#  The pool is checked for free connections every
		#  "cleanup_interval".  If there are free connections,
		#  then one of them is closed.
		cleanup_interval = 300

		#  The idle timeout (in seconds).  A connection which is
		#  unused for this length of time will be closed.
		#
		#  NOTE: A setting of 0 means infinite (no timeout).
		idle_timeout = 600

		#  NOTE: All configuration settings are enforced.  If a
		#  connection is closed because of "idle_timeout",
		#  "uses", or "lifetime", then the total number of
		#  connections MAY fall below "min".  When that
		#  happens, it will open a new connection.  It will
		#  also log a WARNING message.
		#
		#  The solution is to either lower the "min" connections,
		#  or increase lifetime/idle_timeout.
