How To Install Samba4 Active Directory on CentOS 7 Part 2

Posted by

Previously, we have been compile and install samba4 that explained at this link : https://imanudin.net/2014/11/16/how-to-install-samba4-active-directory-on-centos-7-part-1/. Now we will configure dns to integrated with Samba and configure Kerberos. First, we should install bind for dns server

yum install bind bind-sdb

Configure named.conf to listen-on port and allow query from samba server. Also include records dns BIND9_DLZ samba

vi /etc/named.conf

change/add and adjust with the following example

Change line below so that become:

listen-on port 53 { 127.0.0.1; any; };
allow-query     { localhost; any; };

Add line below on the bottom

include "/usr/local/samba/private/named.conf";

check bind version and adjust that version in file named.conf on folder /usr/local/samba/private/

yum info bind
[root@samba4 ~]# yum info bind

Summary     : The Berkeley Internet Name Domain (BIND) DNS (Domain Name System) server
URL         : http://www.isc.org/products/BIND/
License     : ISC
Description : BIND (Berkeley Internet Name Domain) is an implementation of the DNS
            : (Domain Name System) protocols. BIND includes a DNS server (named),
            : which resolves host names to IP addresses; a resolver library
            : (routines for applications to use when interfacing with DNS); and
            : tools for verifying that the DNS server is operating properly.

On my system, bind version is 9.9.4. Open file /usr/local/samba/private/named.conf and using database for bind 9.9.0 so that as below :

vi /usr/local/samba/private/named.conf
dlz "AD DNS Zone" {
    # For BIND 9.8.0
    # database "dlopen /usr/local/samba/lib/bind9/dlz_bind9.so";

    # For BIND 9.9.0
     database "dlopen /usr/local/samba/lib/bind9/dlz_bind9_9.so";
};

change owner of folder /var/named, restart dns service and testing

chown named.named /var/named/
service named restart
host -t SRV _ldap._tcp.imanudin.net.
host -t SRV _kerberos._udp.imanudin.net.
host -t A imanudin.net.

This is results of above command. If your results different, maybe configure of dns still problem

[root@samba4 ~]# host -t SRV _ldap._tcp.imanudin.net.
_ldap._tcp.imanudin.net has SRV record 0 100 389 samba4.imanudin.net.
[root@samba4 ~]# host -t SRV _kerberos._udp.imanudin.net.
_kerberos._udp.imanudin.net has SRV record 0 100 88 samba4.imanudin.net.
[root@samba4 ~]# host -t A imanudin.net.
imanudin.net has address 192.168.26.11

# Configure Kerberos

cp /etc/krb5.conf /etc/krb5.conf.ori
cp /usr/local/samba/private/krb5.conf /etc/krb5.conf

# Testing Kerberos

kinit administrator
klist -e

This is results of testing Kerberos

[root@samba4 ~]# kinit administrator

# Configure kerberos DNS dynamic updates (Optional)

This configuration is optional. You can apply or skip this section. For configuration,adding this line tkey-gssapi-keytab “/usr/local/samba/private/dns.keytab”; in named.conf on options section. See the following example

vi /etc/named.conf
options {
tkey-gssapi-keytab "/usr/local/samba/private/dns.keytab";
listen-on port 53 { 127.0.0.1; any; };

Run the following command to change owner and access on dns.keytab file

chgrp named /usr/local/samba/private/dns.keytab
chmod g+r /usr/local/samba/private/dns.keytab
systemctl enable named.service

check whether any update about dynamic DNS updates with the following command

/usr/local/samba/sbin/samba_dnsupdate --verbose

Hooray, now we have been succeeded install Samba4 as Active Directory and be able join Windows client to Samba4.

Good luck and hopefully useful 😀

  1. Hi!

    Thank you for your tutorial, I’m following step by step but I’m receiving this error:

    Loading ‘AD DNS Zone’ using driver dlopen
    samba_dlz: Failed to connect to /usr/local/samba/private/dns/sam.ldb

    When I try:
    service named restart

    Do you have any tips?

    Thank you again!

    1. Hi Roger,

      It seems that problem while provisioning. Please try to remove sam.ldb and provision again

      rm /usr/local/samba/private/sam.ldb
      /usr/local/samba/bin/samba-tool domain provision

    1. Hi Bernard,

      I just configure my bind same as how to on this guidance. In this guidance, i am using BIND9_DLZ who has been provided by Samba4 all records of dns needed

  3. I figured out why host -t SRV & A is not working.

    I updated the /etc/resolv.conf and added the local dns running on my test server (e.g nameserver ) before I run the host -t SRV & A commands.

    1. Hi Bernard,

      Please make sure your bind service has been starting. Please check any problem on the log in /var/log/messages for tracking and debugging

  4. Hi guys,

    I found a solution for this problem (if you always need it) :

    samba_dlz: Failed to connect to /usr/local/samba/private/dns/sam.ldb

    chmod 777 /usr/local/samba/private/
    chmod 777 /usr/local/samba/private/dns/
    chmod 777 /usr/local/samba/private/dns.keytab
    chmod 777 /usr/local/samba/private/dns/sam.ldb.d
    chmod 777 /usr/local/samba/private/dns/sam.ldb

    It worked for me next that 🙂

    Bye

  5. Hi Iman,
    I have the following errors,

    host -t SRV _kerberos._udp.ashproperties.com.
    Host _kerberos._udp.ashproperties.com. not found: 3(NXDOMAIN)

    host -t SRV _ldap._tcp.ashproperties.com.

    1. Additional info:
      A Kerberos configuration suitable for Samba 4 has been generated at /usr/local/samba/private/krb5.conf
      Once the above files are installed, your Samba4 server will be ready to use

  6. Hi!
    Very nice tutorial!
    Everything is working, but i can’t create a new account in my domain, only the administrator account is working.
    I used: “useradd xxx” and “smbpasswd xxx” but i can’t connect on my domain.

      1. Thank a lot for your answer.
        “samba-tool” is missing on CentOS 7 and i can’t find it with “yum provides samba-tool”
        I’m gonna try with RSAT.

      2. I’ve tried with RSAT on Windows 7 and it’s working!
        I can create a user and connect and the domain.
        Thank a lot!
        But i’m wondering, why can’t i find samba-tool on CentOS 7.

  7. Hello,

    Thanks for your guide.
    While trying to install BIND, package bind-sdb isn’t installed. Package bind installs correctly without errors.
    I get the following output:
    yum install bind-sdb
    Loaded plugins: amazon-id, rhui-lb
    No package bind-sdb available.
    Error: Nothing to do

    Do you have any suggestions?

    Best Regards,
    Konstantin.

  8. Hi iman great post.

    i have an issue with dns update

    01-Oct-2015 05:10:27.023 database: info: samba_dlz: starting transaction on zone eproyiv.cu
    01-Oct-2015 05:10:27.026 update-security: error: client 172.168.1.4#1370: update ‘eproyiv.cu/IN’ denied
    01-Oct-2015 05:10:27.026 database: info: samba_dlz: cancelling transaction on zone eproyiv.cu

    i check everything and seem to be allright

    1. Hi David,

      You can try to restart your Workstation and re-login to Samba4. Please make sure you have configured DNS Dynamic Address

  9. service named start
    Failed to connect to /usr/local/samba/private/dns/sam.ldb
    Still looking for an answer for this! Therefor neither LDAP nor kerberos are not working 🙁 I gave permission to this file as an owner for named but not working..

    1. Hi,

      Please try to change permission with 777. For example

      chmod -R 777 /usr/local/samba/private/dns/
      

      Sometimes, i also use this options for make sure nothing problem with my configuration. But problem in permissions 😉

  10. You saved the day! Now it works great thx a lot 🙂 How i’m silly
    Let me add something; BIND must have installed before provisioning bcoz during the provision samba generates /usr/local/samba/private/named.conf! I mean If bind installed already than samba creates the right configuration file..
    Attention! If you try to re-enable SElinux!
    Must add the following rules;
    firewall-cmd –permanent –add-port=53/tcp
    firewall-cmd –permanent –add-port=53/udp
    firewall-cmd –permanent –add-port=88/tcp
    firewall-cmd –permanent –add-port=88/udp
    firewall-cmd –permanent –add-port=135/tcp
    firewall-cmd –permanent –add-port=137/tcp
    firewall-cmd –permanent –add-port=137/udp
    firewall-cmd –permanent –add-port=138/udp
    firewall-cmd –permanent –add-port=139/tcp
    firewall-cmd –permanent –add-port=389/tcp
    firewall-cmd –permanent –add-port=389/udp
    firewall-cmd –permanent –add-port=445/tcp
    firewall-cmd –permanent –add-port=464/tcp
    firewall-cmd –permanent –add-port=464/udp
    firewall-cmd –permanent –add-port=636/tcp
    firewall-cmd –permanent –add-port=1024-5000/tcp
    firewall-cmd –permanent –add-port=1024-5000/udp
    firewall-cmd –permanent –add-port=3268/tcp
    firewall-cmd –permanent –add-port=3269/tcp
    firewall-cmd –permanent –add-port=5353/tcp
    firewall-cmd –permanent –add-port=5353/udp
    And restart.. Restart again 🙂

    Thx again man you are great
    Best regards

  11. May I ask question?
    I have some problem, when I running “service named restart”.
    It can’t start.

            cp /usr/local/samba/private/krb5.conf /etc/krb5.conf
            
    1. I had this problem as well and the cause was /etc/resolv.conf pointing to an external DNS server in stead of DNS server for Samba.

        Finished upgrading DNS

        After that got the same error……..

          1. Its working fine in Centos-6 with bind9.8 . But in Centos7 with Bind9.9 always the same problem.

            Selinux and firewall is off in Centos 7 but still comes the same problem.

  15. hi! i have a problem! i need to join linux machine on samba4 domain. I used this tutorial to create samba AD. At moment the client have some problem with DNS, the error is “Host kclient.samdom.er.com not found: 3(NXDOMAIN)”. File hosts it’s properly configured. From server i can ping the client and viceversa. Windows works good in domain, i also a problem with linux join.

    1. Hi Gennaro,

      For Linux client who join domain, i am not yet try in other Linux. I am usually use openSUSE/SLES for join domain using YAST (Wizard/GUI) 😀

      1. Ok thank. I have another question. I need manage some users from kerberos database with “kadmin” and generate some keytabs for clients. With samba4 i add users with “samba-tool” and kerberos works fine but how can i generate keytabs and to use kadmin interface?? In another server i have configured kerberos generating a database and add user principals, the kadmin interface worked fine. In your tutorial what is the kerberosdatabase? whats is the principals kerberos?

    1. Hi Edgar,

      Please check whether your DNS server has been worked or not. You can check from services of BIND, nslookup command or dig and firewall configuration

    restart named.service sudah bisa mas..guidance jg sudah saya ikutin..tapi pas instruksi berikut..
    [root@samba ~]# host -t SRV _ldap._tcp.ito.co.id.
    ;; connection timed out; trying next origin
    ;; connection timed out; no servers could be reached
    [root@samba ~]# host -t SRV _kerberos._udp.ito.co.id.

    ;; connection timed out; no servers could be reached
    [root@samba ~]# host -t A ito.co.id
    ;; connection timed out; trying next origin
    ;; connection timed out; no servers could be reached

    whats wrong mas? need help pls..
    thx bro.

    1. Hi mas,

      Pastikan services DNS nya sudah jalan. Coba cek pake perintah nslookup jika pake perintah host tidak bisa

      nslookup ito.co.id
      

      Pastikan IP nameserver yang pertama mengarah ke localhost/IP server itu sendiri

  19. Dear Mas Iman..

    IP nameserver sudah saya arhkan ke ip server..domain ito.co.id masih belum kebaca mas. nslookup ito.co.id tidak ada.

  22. Hi firs off very nice guide.

    I got everything to work. But i have this 1 problem that the DNS (bind) wont resolve names to ip addresses. i can ping googles ip address but not http://www.google.com.

    Any suggestions to where the configuration is messed up ?

  23. mas Iman, setelah saya menambahkan include “/usr/local/samba/private/named.conf”; pada konfigurasi /etc/named.conf, dan saya cek pada named.conf tsb sudah ada dgn menggunakan bind 9.8, saat saya restart namednya muncul error not found file named.conf tsb, kira2x masalahnya apa ya mas? karena sata install di SLES 12 konfigurasi tsb tidak masalah.

    1. Hi Abhi CN,

      How you get webmail.kplinux.com as CNAME from linus7.kplinus.com? AFAIK, if you have configured bind9 DLZ as internal DNS for Samba4, the server only have A records for domain and hostname. And do not have webmail as CNAME for another Name/Hostname

  31. Salam Jempol untuk Mas Imanudin,.

    saya sudah mengikuti tutorial diatas, dan berhasil.
    yg jadi masalah, ketika saya coba koneksikan mesin windows 7 ke domain yg baru saya buat tsb, bisa muncul Halaman Username & Password utk Domain yg baru saya buat.
    tetapi setelah username saya masukkan (Administrator) dan Password nya, lalu muncul error:

    ” Computer Name/Domain Changes
    An Attempt to resolve the DNS name of a domain controller in the domain being joined has failed. Please verify this client is configured to reach a DNS server that can resolve DNS names in the target domain.
    For Information about network trouble shorting, see windows help. ”

    Mohon di bantu utk permasalahan ini ya Mas,.

    Terima Kasih.

  32. Mas Iman,
    di step yang merubah vi /usr/local/samba/private/named.conf
    tidak saya temukan file tersebut.

    cd /usr/local/samba/private/
    [root@centos private]# ls
    dns.keytab ldap_priv secrets.ldb
    dns_update_cache msg.sock secrets.tdb
    dns_update_list netlogon_creds_cli.tdb share.ldb
    encrypted_secrets.key privilege.ldb smbd.tmp
    hklm.ldb sam.ldb spn_update_list
    idmap.ldb sam.ldb.d tls
    krb5.conf schannel_store.tdb
    ldapi secrets.keytab

    Apakah tidak masalah kalau saya create file baru disitu ?

  33. how to implement the security and GPO in window and Linux client. and one more thing.how to join the linux client in linux DC.

    1. Hello,
      You can apply GPO only for Windows. The samba4 project developed for replacing Windows Server AD.
      If you are using openSUSE ,you can use YAST to join (using wizard)

  34. Salam kenal mas, saya sudah mengikuti tutorial di atas. Saya ada kendala saat melakukan perintah service named restart muncul keterangan :
    Job for named.service failed because the control process exited with error code. See “systemctl status named.service” and “journalctl -xe” for details.

    Kebetulan versi bind yang terinstall di saya adalah versi 9.11. Saya sudah edit bagian /usr/local/samba/private/named.conf menjadi :
    database “dlopen /usr/local/samba/lib/bind9/dlz_bind9_9.so”;

    Tapi saat saya restart error tetap sama. Mohon solusinya
