Hello,

Pre-requisites:
1. AD with Unix attributes (you're able to do without Unix attributes,
but our setup is based on it)
2. AD Kerberos and LDAP advertised in DNS (should already be in place if
you're using MS DNS servers; check that with dig -t srv
_ldap._tcp.example.com and dig -t srv _kerberos._udp.example.com where
example.com is your AD domain name).
3. CFEngine with cfgen on Linux machines (or you'll need to just read
the automation file auth_sss.cf yourself and do the changes listed and
replace [% environments %] with actual data.
4. Proper SSL certificates for AD LDAP service or a certificate that you
will add to ca-certificates on Linux clients (or you'll need to pass nss
data through ldap:// instead of ldaps://)
5. AD LDAP reader account with minimal set of permissions.

Procedure:
1. Include auth_sss.cf in CFEngine and use the bundle auth_sss. as
included in the attachments.
2. Enter the domain details and AD reader details as input variables to
the auth bundle and cfgen.
3. Run CFEngine with that.

Outcome:
1. The machine does not need to wait for network during boot time
(unless for non-sss related reasons).
2. You are not relying on a commercial company to provide you with auth
services.
3. It works way better than winbind3.
4. The logged-in user gets a Kerberos ticket which he can use to SSO to
services (like windows shares and printers, ldap and kerberos enabled
webpages).

# Sample configuration file for the Samba suite for Debian GNU/Linux.
#
#
# This is the main Samba configuration file. You should read the
# smb.conf(5) manual page in order to understand the options listed
# here. Samba has a huge number of configurable options most of which 
# are not shown in this example
#
# Some options that are often worth tuning have been included as
# commented-out examples in this file.
#  - When such options are commented with ";", the proposed setting
#    differs from the default Samba behaviour
#  - When commented with "#", the proposed setting is the default
#    behaviour of Samba but the option is considered important
#    enough to be mentioned here
#
# NOTE: Whenever you modify this file you should run the command
# "testparm" to check that you have not made any basic syntactic 
# errors. 
# A well-established practice is to name the original file
# "smb.conf.master" and create the "real" config file with
# testparm -s smb.conf.master >smb.conf
# This minimizes the size of the really used smb.conf file
# which, according to the Samba Team, impacts performance
# However, use this with caution if your smb.conf file contains nested
# "include" statements. See Debian bug #483187 for a case
# where using a master file is not a good idea.

[global]

## Browsing/Identification ###

# Change this to the workgroup/NT-domain name your Samba server will part of
   workgroup = [% domain.short %]

# Windows Internet Name Serving Support Section:
# WINS Support - Tells the NMBD component of Samba to enable its WINS Server

# Note: Samba can be either a WINS Server, or a WINS Client, but NOT both

# This will prevent nmbd to search for NetBIOS names through DNS.
   dns proxy = no

# What naming service and in what order should we use to resolve host names
# to IP addresses

#### Networking ####

# The specific set of interfaces / networks to bind to
# This can be either the interface name or an IP address/netmask;
# interface names are normally preferred
;   interfaces = 127.0.0.0/8 eth0

# Only bind to the named interfaces and/or networks; you must use the

# It is recommended that you enable this feature if your Samba machine is
# not protected by a firewall or is a firewall itself.  However, this
# option cannot handle dynamic or non-broadcast interfaces correctly.

# If you want Samba to only log through syslog then set the following

# should go to /var/log/samba/log.{smbd,nmbd} instead. If you want to log
# through syslog you should set the following parameter to something higher.
