# 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.

|

|
#
|
||
|
|
# 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.

|
# 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
