Setting up Samba as an Active Directory Domain Controller on Debian 9 Stretch


Samba is great project and if wont make Samba AD DC today is very simple. More about Samba look at

Preparing the Installation

  • select hostname(,domain name(
  • installation and configure of time server (ntp)
  • installation and configure of domain name system (bind9)


Set hostname of my Samba ad dc server:

hostnamectl set-hostname

Edit hosts:

nano /etc/hosts dc1

Installation and configure of time server (ntp):

apt-get install ntp

Change settings in ntp.conf

nano /etc/ntp.conf

logfile   /var/log/ntp.log
driftfile /var/lib/ntp/ntp.drift
ntpsigndsocket /var/lib/samba/ntp_signd/

pool iburst
pool iburst
pool iburst
pool iburst

restrict -4 default kod notrap nomodify nopeer noquery limited
restrict source notrap nomodify noquery
restrict default kod nomodify notrap nopeer mssntp

Fix bug apparmor (Thanks to  Louis van Belle):

Enable the local file part for ntpd:

sed -i 's[#include <local/usr.sbin.ntpd>[include <local/usr.sbin.ntpd>[g' /etc/apparmor.d/usr.sbin.ntpd

NTPD fix.:

echo "
  # To sign replies to MS-SNTP clients by the smbd daemon /var/lib/samba
  /var/lib/samba/ntp_signd r,
  /var/lib/samba/ntp_signd/{,*} rw,

  # samba4 winbindd pipe
  /{,var/}run/samba/winbindd r,
  /{,var/}run/samba/winbindd/pipe rw,

  # samba4 winbindd privileged pipe ? Needed?
  /var/lib/samba/winbindd r,
  /var/lib/samba/winbindd/pipe rw,

" >> /etc/apparmor.d/local/usr.sbin.ntpd

Installation and configure of domain name system (bind9):

Instalirati bind9 paket:

apt-get install bind9

Configure neamed.conf.options

nano /etc/bind/named.conf.options

//  Add any subnets or hosts you want to allow to use this DNS server
acl internal {;;

options {

        auth-nxdomain yes;
        directory "/var/cache/bind";
        notify no;
        empty-zones-enable no;
        listen-on-v6 { none; };

        forwarders {

        allow-query { internal; };
        allow-recursion { internal; };
        allow-transfer { none; };

Finale step start service and test ntp and bind9:

systemctl restart ntp.service bind9.service

Set in resolv.conf our bind9:

nano /etc/resolv.conf


Now test bind9:

Test the localhost forward zone):

host -t A localhost 

Default respond is:

Using domain server:

localhost has address

To test the reverse zone:

host -t PTR 

Default respond is:

Using domain server:
Aliases: domain name pointer localhost.

Test NTP server:

ntpdate -q

Default respond is:

server, stratum 2, offset -0.000073, delay 0.02602
24 Apr 12:10:30 ntpdate[10143]: adjust time server offset -0.000073 sec


Installing Kerberos & Samba and configure Bind9 with Samba:

  • Installing Kerberos and configure
  • Installing Samba and configure
  • Configure Bind9 to work with Samba

Installing Kerberos and configure:

apt-get install krb5-config krb5-user

Configure krb5.conf

nano /etc/krb5.conf

        default_realm = INTERNAL.EXAMPLE.COM
        dns_lookup_realm = false
        dns_lookup_kdc = true


Installing Samba and configure:

Debian bring Samba 4.5.16 but that version don't have JSON module (Need 4.7+ for JSON), and I find great repository by Louis van Belle (Please feel to free Donate to Louis).

Add repos:

wget -O - | apt-key add -

echo "# AptVanBelle repo for samba." | sudo tee /etc/apt/sources.list.d/van-belle.list

echo "deb stretch-samba410 main contrib non-free" | sudo tee -a /etc/apt/sources.list.d/van-belle.list

apt-get update

Install samba:

apt-get install samba winbind attr acl

Configure service samba for AD DC:

systemctl stop smbd nmbd winbind
systemctl mask smbd nmbd winbind
systemctl disable smbd nmbd winbind
systemctl unmask samba-ad-dc
systemctl enable samba-ad-dc
systemctl daemon-reload

Configure Samba as AD DC:

If exist old configuration of samba /etc/samba/smb.conf then make backup of config and delete.

cp /etc/samba/smb.conf /etc/samba/smb.conf.bck
rm /etc/samba/smb.conf

samba-tool domain provision --use-rfc2307 --realm INTERNAL.EXAMPLE.COM --domain EXAMPLE --server-role dc --dns-backend=BIND9_DLZ  --adminpass StrongPassword

Configure Bind9 to work with Samba:

Add under section options { }

nano /etc/bind/named.conf.options

allow-update {; };

// DNS dynamic updates via Kerberos (optional, but recommended)
//tkey-gssapi-keytab "/var/lib/samba/private/dns.keytab";    //samba 4.8 and lower
tkey-gssapi-keytab "/var/lib/samba/bind-dns/dns.keytab";    // samba 4.9 and up


Add rndc.key, bind-dns include in named.conf

nano /etc/bind/named.conf.local

include "/etc/bind/rndc.key";
    controls {
     inet allow { localhost; } keys { rndc-key;};

include "/var/lib/samba/bind-dns/named.conf";

Set pemission for Bind9:

setfacl -m g:bind:r /etc/krb5.conf
setfacl -m g:bind:r /var/lib/samba/bind-dns

Set permission for NTP:

chown root:ntp /var/lib/samba/ntp_signd/
chmod 750 /var/lib/samba/ntp_signd/

Restartati all services:

systemctl restart bind9.service ntp.service samba-ad-dc.service

Test Kerberos:

kinit administrator

Test DNS over Samba:

samba_dnsupdate --verbose

* Change from internal samba dns to bind9_dlz use (If you are running a older samba ad-dc and then upgrade as shown, The file dns.keytab isnt move the the new folder, you need todo that manualy. Its already in the debian bugreport for samba):

samba_upgradedns --dns-backend=BIND9_DLZ

Tweak service start order for Samba then Bind9 and disable reload for Bind9(bug sometime confuze Samba) :


systemctl edit samba-ad-dc.service 

Add in file:

[Unit] bind9.service


systemctl edit bind9.service

Add in file:


Test Samba:

samba-tool domain info
net ads info
net rpc info -U administrator
wbinfo -P
wbinfo -t
wbinfo -pPt 

Congratulations enjoy in Samba World.

How to install self hosted Mozilla Sync for Pale Moon in 3 min on Debian 9


My default internet browser is Pale Moon and I'm very satisfied. Very stable, in six months of use has never collapsed or obstructed. The rendering speed of the web site is great thanks to the Goanna layout engine. Compatibility with NPAPI plugin is supported (some apps need that plugin). Pale Moon is multi platform browser and work on Linux, Windows and soon on Mac. This is not "one man project". Read "BLOG: This is rumor control, here" before you make your prejudices about this internet browser.


Let's start

Open console and add Jurisic repository and install mozsync package:

echo "deb stretch main contrib non-free" >> /etc/apt/sources.list.d/jurisic.list
wget -q -O- | apt-key add -
apt-get update
apt-get install mozsync

Strong recommendation to turn on support https on new fresh installed apache.
Short example how to enable ssl:

a2enmod ssl
a2ensite default-ssl
systemctl restart apache2

Now configure service, open address (replace ip with Your IP/dns name):

For my personal using no need MySQL database, I select SQLite and press OK.

Congratulations you have successfully installed the mozilla sync 1.1 server!

Setup Sync in Pale Moon

Click on Tools->Preferences then click on tab Sync:

Now click on "Set Up Pale Moon Sync"

Fill form with e-mail,password and under server select "Use a custom server ..." and enter link of Your sync server.

Click Next to finish proces:

That is all. Enjoy in Pale Moon browser and own Sync service !!!

De-Googling my phone

For a long time I've been using the Xiaomi Mi 5 phone with MUI interface that is base on based Android. That means that on my phone I have installed Bloatware that came with MIUI and additionally with Android. The result of all this is the weaker performance of mobile phone, faster battery discharge, the disruption of privacy and the very questionable security of the data I have on my mobile.



The main objection, from my point of view, is that I must have google account to access Android apps. Why couldn’t I install an application anonymously? After long search for alternatives for Google Play, I found the Yalp Store program from the F-Droid repository. I thought Yalp was the answer to the earlier question, so I deleted the google account from my cell phone and all looked just like I wanted.


Screenshot F-Droid Screenshot Yalp Store Screenshot Blokada


As I often use internet browser on my mobile phone, I wanted to install a program for blocking unwanted ads. I use the uBlock Origin on my computer and I'm very satisfied, and I found Blokada for the mobile and now there is a shocking discovery. All the applications I received with my cell phone (pre-installed) and the apps I installed from my google store were still trying to send some information to google. Even if I did not have a google account assigned to a mobile, still all apps generated network traffic towards google. Paradoxically, when I returned google account to my cell phone, I still generated the traffic but less.

Then I downloaded a couple of programs from F-Droid and network packages did not generate from those applications but only from google play service and that points to only one thing. Google analyzes what you have installed on your mobile phone even though you have not used their service.


I found interesting articles on the google service Youtube about google android:


After active search for alternative andorid os, I found various projects but one of them particularly attracted my attention - /e/ project. Unfortunately, the project is just in the initial phase so I looked for something that would be compatible with the android os and that there is no installed default google play service with the loads of bloatware installed in it. The answer is an open source LineageOS project where google play service can, but it does not have not be installed. Luckily for me, my cell phone Xiaomi Mi 5 is officially supported and I am starting the great adventure great adventure.


Complete manual for installation can see at link but in practice it looked like this:

1. Download software for fastboot

I using Debian GNU/Linux 9 and installation of fastboot is very simple:

apt-get install fastboot

2. Download TWRP loader for Xiaomi Mi 5 (phone need to be unlock to apply new loader)


3. Download LingeageOS za Xiaomi Mi 5


4. Start phone in fastboot and flash loader

With the device powered off (connect phone with pc -usb ), hold Volume Down + Power. Keep holding both buttons until the word “FASTBOOT” appears on the screen, then release and in linux console put command:

fastboot flash recovery twrp-3.2.3-0-gemini.img

After success upload of image, I power off phone, then hold Volume Up + Power. Keep holding both buttons until TWRP appears on screen. First all wipe (dalvik,cache,data,internal storage)

5. Copy LineageOS-a and installation

First open on my PC file explorer (Nemo) and copy in internal memory of phone, then in TWRP select Install and select zip file. Waiting to complete install and reboot phone and new LineageOS is ready for me.


The first thing I did when I started LineageOS, I started browsing and I installed F-Droid. I've installed a few programs that are very useful. Some programs are replacement for some programs that I used before, and for some, unfortunately, I have no alternative.

LineageOS is based on the original Android and applications, so I've replaced a default google keyboard with a Simple Keyboard, an e-mail client with K-9 Mail in combination with OpenKeychain and google chrome with Privacy Browser.


Lists of programs on my phone now:

Namjena Banned Alternative
App store Google Play F-Droid
E-mail client Gmail/Mail K-9 Mail
Email Encryption - OpenKeychain
Instant Messaging WhatsApp or Viber Conversations or Telegram
SMS Messaging - Silence
Media Youtube NewPipe
Password Managers LastPass Password Store
Social Network Facebook dandelion*
Social News Twiter Tusky or Mastalab
Enterprise Suite Google Apps Nextcloud
Internet Browser Google Chrome Privacy Browser
Navigation Google Maps OsmAnd~
Phone Contacts Google Contacts DAVdroid
Phone Calendars Google Calendars DAVdroid
Phone Tasks Google Tasks Tasks
PDF Viewer Google PDF Viewer Document Viewer
Office Documents Google Docs LibreOffice Viewer
Keyboard Google Keyboard Simple Keyboard
File Share & Sync Google Disk, Files Go Nextcloud

Did I achieve my goal? Do I have more privacy and security on my mobile? Yes and no, it is difficult to answer on that but surely the cell phone now has fewer unwanted programs and the battery on my mobile lasts longer. This is one step towards a better OS but it is still far from the destination I am heading for. I have great expectations from /e/ project and the time will show in which direction will it go.
