For an Active Directory setup with sernet-samba 4.0.9 on CentOS, I 
believe the only package that needs to be installed is:

# yum install sernet-samba-ad

Prerequisites seem to be:

- make sure that this points at your existing Active Directory server 
(if you have one)

- configure this if you have an existing AD controller and test using 
'kinit administrator'

  default_realm = ADDOMAIN.EXAMPLE.COM
  dns_lookup_realm = true
  dns_lookup_kdc = true

- set to "permissive" while you configure the server
- "service auditd rotate" to rotate the log files prior to install/setup
- "cat /var/log/audit/audit.log | audit2allow" to check for exceptions
- fix SELinux issues, then go back to "enforcing" mode

After that you can follow the instructions at either:


The only service that runs at startup is (AFAIK) "sernet-samba-ad".  I 
am moderately sure that the other (3) services (sernet-samba-nmbd, 
sernet-samba-smbd, sernet-samba-winbindd) do not need to run if you are 
doing an Active Directory domain.  But I'm not certain yet because I'm 
in the process of testing this in our environment.
