[Samba] Question Wiki Setup a Samba Active Directory Domain Controller

Hi again,

I refer to
https://wiki.samba.org/index.php/Setup_a_Samba_Active_Directory_Domain_Controller#Testing_your_Samba_Domain_Controller

Thank you for this great wiki! I run all the tests and everything looks
perfect!

I encounter just a little difference here. Actually I thought that there
should be no Master and Workgroup for a AD DC. (as given in the wiki and
in Stefan Kania's book "Samba 4) 

Why is it at my installation (Debian 8.2., Samba 4.1.17)?... ow, and after
I restarted the computer samba, nmbd and smbd were running.... I didn't
install any start script. I thought nmbd is not needed on AD DC, is it?
I'd also prefer a setup where my windows client will not be able to browse
the AD DC.

        workgroup = BLA
        realm = AD.BLA.AT
        netbios name = MYHOSTNAME
        server role = active directory domain controller
        dns forwarder = my dns IP
        idmap_ldb:use rfc2307 = yes

[netlogon]
        path = /var/lib/samba/sysvol/ad.bla.at/scripts
        read only = No

[sysvol]
        path = /var/lib/samba/sysvol
        read only = No

Actually this mailing list keeps me alive. As I cannot give you anything
back at the moment (still DAU knowledge status here), is it possible to
donate a little money? If appreciated, send a link or howto.

kind regards, birgit

You are correct, there is no master in an AD domain, but you still need 
the workgroup name. I cannot speak for the book having never read it, 
but there are several problems with the conf files on the website you 
provided earlier. I would suggest that you stick with the Samba wiki and 
asking questions here :-)

If you have both the samba and nmbd daemons running, then you have 
something wrong, the samba daemon has its own nmbd built in.
If you installed via apt-get, you would probably get nmbd installed in 
/usr/sbin. You need to stop nmbd being started on boot, but just how you 
would this, I do not know because you are using Jessie that uses systemd.

[Samba] Question Wiki Setup a Samba Active Directory Domain Controller

Hello,

Probably problem is numer 3... see below....

All of them are running after restart of computer:

# /etc/init.d/samba-ad-dc status
● samba-ad-dc.service - LSB: start Samba daemons for the AD DC
   Loaded: loaded (/etc/init.d/samba-ad-dc)
   Active: active (running) since Son 2015-10-04 23:14:36 CEST; 18h ago

# /etc/init.d/samba status
● samba-ad-dc.service - LSB: start Samba daemons for the AD DC
   Loaded: loaded (/etc/init.d/samba-ad-dc)
   Active: active (running) since Son 2015-10-04 23:14:36 CEST; 18h ago

# /etc/init.d/nmbd status
● nmbd.service - LSB: start Samba NetBIOS nameserver (nmbd)
   Loaded: loaded (/etc/init.d/nmbd)
   Active: active (exited) since Son 2015-10-04 23:14:36 CEST; 18h ago

 # /etc/init.d/smbd status
● smbd.service - LSB: start Samba SMB/CIFS daemon (smbd)
   Loaded: loaded (/etc/init.d/smbd)
   Active: active (exited) since Son 2015-10-04 23:14:36 CEST; 18h ago

winbind is not running.

And yes, nmbd is in /usr/sbin.

I checked my /etc/init.d/samba-ad-dc and it is the same as
http://anonscm.debian.org/gitweb/?p=pkg-samba/samba.git;a=blob_plain;f=debian/samba.samba-ad-dc.init;h=3132d2e367675f822342a5b7bc2e50c046aa3b8f;hb=HEAD
which is recommended for Debian on
https://wiki.samba.org/index.php/Samba4/InitScript .

I got all those init scripts set to 755 like recommended:
/etc/init.d # ls -l samba samba-ad-dc nmbd smbd
-rwxr-xr-x 1 root root 1948 Mär  7  2015 nmbd
-rwxr-xr-x 1 root root 1266 Mär  7  2015 samba
-rwxr-xr-x 1 root root 2299 Mär  7  2015 samba-ad-dc
-rwxr-xr-x 1 root root 1930 Mär  7  2015 smbd

As far as I understand /etc/init.d/samba starts samba-ad-dc, smbd and nmbd
and the init each of them themselves check if the process is needed or
not. As far as I can understand the /etc/init.d/nmbd file nmbd should not
be started but exit, because I have an active directory domain controller.

I tested on the command line:>samba-tool testparm --parameter-name="server role"active directory domain controller

I do not understand that behaviour. Furthermore I do not understand why I
do have to have a /etc/init.d/samba additionally to
/etc/init.d/samba-ad-dc. So what I did was stopping everything and just
start /etc/init.d/samba-ad-dc (which does not start nmbd and smbd). Then I
did all recommended tests of the Wiki again. Everything's works fine. But
am I going to run into problems later on? Do I need to get rid of init
files? I attached /etc/init.d/samba and /etc/init.d/nmbd files below.

Please can somebody point out 
1) which init scripts/processes are necessary for Samba 4 AD DC 
2) and most important: how to deactivate the unnecessary ones at startup
3) do I have mixed up my installation? To me it seems I somehow have a
samba 4 pdc and a samba 4 AD DC simultaneusly installed. Ow, now I
remember at provision I was informed to remove /etc/samba/smb.conf (the
one that was produced at samba install with aptitude which included
"server role = standalone server"). I renamed it to smb_old.conf and
then
the AD AC installation succeeded. But did it somehow install those
unnecessary processes as wellt? If yes, how to clean up? (I could also
start the whole installation from scratch if it is the easiest way to do
it.)

kind regards, birgit

When I just start "/etc/init.d/samba-ad-dc start" nmbd and smbd are
not
started.
