OK, sorry as this is a long mail because Im going to include as much config
as possible.
I have been playing around trying to get this to work with little success
though the debug error messages have changed since yesterday
Im having trouble getting freeradius to use ntlm_auth - the error massage is
now stating a permission error..
Just to confirm, Im following the steps on deployingradius.com ..
PAP has been tested and is working
Samba configured and working
wbinfo -a = works, having tested multiple logins
ntlm_auth --request-nt-key --domain=MYDOMAIN --username=user
--password=password = working, again tested with multiple logins
radtest user password localhost 0 testing123 = does not work, see debug info
at end of email..
Contents of/raddb/modules/ntlm_auth file
#
# For testing ntlm_auth authentication with PAP.
#
# If you have problems with authentication failing, even when the
# password is good, it may be a bug in Samba:
#
# https://bugzilla.samba.org/show_bug.cgi?id=6563
#
exec ntlm_auth {
wait = yes
program = "/usr/local/etc/raddb/modules/ntlm_auth --request-nt-key
--domain=xxxxxxxxxx --username=%{mschap:User-Name}
--password=%{User-Password}"
}
I have modified the authenticate sections of the raddb/sites-enabled/default
file, and of the raddb/sites-enabled/inner-tunnel file
Listed below are the authenticate sections only as that is all I have
changed....
sites-enabled/default
authenticate {
#
# PAP authentication, when a back-end database listed
# in the 'authorize' section supplies a password. The
# password can be clear-text, or encrypted.
Auth-Type PAP {
pap

#
# Most people want CHAP authentication
# A back-end database listed in the 'authorize' section
# MUST supply a CLEAR TEXT password. Encrypted passwords
# won't work.
Auth-Type CHAP {
chap

#
# MSCHAP authentication.
Auth-Type MS-CHAP {
mschap

# ntlm authentication.
ntlm_auth
# If you have a Cisco SIP server authenticating against
# FreeRADIUS, uncomment the following line, and the 'digest'
# line in the 'authorize' section.
digest
#
# Pluggable Authentication Modules.
# pam
#
# See 'man getpwent' for information on how the 'unix'
# module checks the users password. Note that packets
# containing CHAP-Password attributes CANNOT be authenticated
# against /etc/passwd! See the FAQ for details.
#
# For normal "crypt" authentication, the "pap" module should
# be used instead of the "unix" module. The "unix" module should
# be used for authentication ONLY for compatibility with legacy
# FreeRADIUS configurations.
#
unix
# Uncomment it if you want to use ldap for authentication
#
# Note that this means "check plain-text password against
# the ldap database", which means that EAP won't work,
# as it does not supply a plain-text password.
# Auth-Type LDAP {
# ldap
# }
#
# Allow EAP authentication.
eap
#
# The older configurations sent a number of attributes in
# Access-Challenge packets, which wasn't strictly correct.
# If you want to filter out these attributes, uncomment
# the following lines.
#
# Auth-Type eap {
# eap {
# handled = 1
# }
# if (handled && (Response-Packet-Type == Access-Challenge)) {
# attr_filter.access_challenge.post-auth
# handled # override the "updated" code from
attr_filter
# }
# }
}
#
raddb/sites-enabled/inner-tunnel file - again just showing the bit
modified..

DEFAULT Auth-Type = ntlm_auth has been added to the top of the users
