+# 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
+
+ #
+ # This 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.
+ #
+ # For Samba 4, you should also set the "ntlm auth" parameter
+ # in the Samba configuration:
+ #
+ # ntlm auth = yes
+ #
+ # or
+ #
+ # ntlm auth = mschapv2-and-ntlmv2-only
+ #
+ # This will let Samba 4 accept the MS-CHAP authentication
+ # method that is needed by FreeRADIUS.
+ #
+ # Depending on the Samba version, you may also need to add:
+ #
+ # --allow-mschapv2
+ #
+ # to the command-line parameters.
+ #
+# ntlm_auth = "/path/to/ntlm_auth --request-nt-key --allow-mschapv2 --username=%{%{Stripped-User-Name}:-%{%{User-Name}:-None}} --challenge=%{%{mschap:Challenge}:-00} --nt-response=%{%{mschap:NT-Response}:-00}"
+
+ #
+ # 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.
+ #
+# winbind_username = "%{mschap:User-Name}"
+# winbind_domain = "%{mschap:NT-Domain}"
+
+ #
+ # 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
+ # user in the correct casing in the backend, and retry
