Tips Samba : Migrating From Windows Server To Samba 4 Part 1

Untuk melakukan Migrasi dari Windows Server ke Samba 4, sebenarnya hal yang dilakukan sama persis dengan yang dijelaskan pada artikel sebelumnya : https://www.imanudin.com/2013/05/21/tips-samba-membuat-bdcjoin-a-domain-as-a-dc-pada-samba-4/ dengan sedikit modifikasi dan tambahan konfigurasi. Untuk memudahkan pemahaman, berikut persiapan yang dilakukan :

INFORMASI SISTEM

Windows Server

Domain      : imanudin.com
Hostname    : windowsdc
IP Address  : 192.168.56.26

Linux Server

Domain     : imanudin.com
Hostname   : samba4
IP Address : 192.168.56.11
DNS 1      : 192.168.56.26 (Mengarah ke IP Windows Server)
DNS 2      : 192.168.56.11 (Mengarah ke IP dirinya sendiri)

INSTALASI DAN KONFIGURASI SAMBA 4

Sistem Operasi yang saya gunakan adalah CentOS dengan panduan instalasi merujuk pada artikel berikut :

Ingat, jangan lakukan provisioning pada panduan part 4. Jika terlanjur melakukan provisioning, hapus file smb.conf pada folder instalasi Samba 4

Buang file smb.conf pada folder /usr/local/samba/etc/ dan edit file krb5.conf
[code lang=’bash’]
rm /usr/local/samba/etc/smb.conf
vi /etc/krb5.conf
[/code]
Isi seperti pada contoh berikut :
[code lang=’bash’]
[libdefaults]
dns_lookup_realm = true
dns_lookup_kdc = true
default_realm = IMANUDIN.COM
[/code]
Testing koneksi DNS dan Kerberos
[code lang=’bash’]
kinit administrator
klist
[/code]
Jalankan perintah berikut sebagai root
[code lang=’bash’]
/usr/local/samba/bin/samba-tool domain join imanudin.com DC -Uadministrator –realm=imanudin.com –dns-backend=BIND9_DLZ
[/code]
Berikut adalah proses join domain yang dilakukan :

[root@samba4 ~]# /usr/local/samba/bin/samba-tool domain join imanudin.com DC -Uadministrator –realm=imanudin.com –dns-backend=BIND9_DLZ

Joined domain IMANUDIN (SID S-1-5-21-1957489133-1293898768-425495568) as a DC

Tambahkan A record server Samba4 pada DNS Server. Hal ini dilakukan agar domain imanudin.com mengenali ip Samba4
[code lang=’bash’]
/usr/local/samba/bin/samba-tool dns add 192.168.56.26 imanudin.com samba4 A 192.168.56.11 -Uadministrator
[/code]
Keterangan : IP Address 192.168.56.26 merupakan IP Address Windows Server, samba4 merupakan nama hostname pada server Linux yang saya buat dan 192.168.56.11 merupakan ip address yang digunakan pada server Linux.

Tambahkan juga objectGUID pada DNS
[code lang=’bash’]
/usr/local/samba/bin/ldbsearch -H /usr/local/samba/private/sam.ldb ‘(invocationid=*)’ –cross-ncs objectguid
[/code]
Berikut output yang dihasilkan :

# record 1
dn: CN=NTDS Settings,CN=SAMBA4,CN=Servers,CN=Default-First-Site-Name,CN=Sites,CN=Configuration,DC=imanudin,DC=com
objectGUID: 54cab258-2d26-4273-90c1-f88397bcb5ea

# record 2
dn: CN=NTDS Settings,CN=WINDOWSDC,CN=Servers,CN=Default-First-Site-Name,CN=Sites,CN=Configuration,DC=imanudin,DC=com
objectGUID: 7e84d99e-5d0e-4ade-91a1-30f9f5970988

# returned 2 records
# 2 entries
# 0 referrals

Perhatikan tulisan yang diberi tanda tebal, object GUID yang dimiliki oleh Linux server Samba4 adalah 54cab258-2d26-4273-90c1-f88397bcb5ea, record tersebut harus dibuat dan dimasukkan pada DNS server agar Linux server Samba 4 dapat digunakan sebagaimana mestinya
[code lang=’bash’]
/usr/local/samba/bin/samba-tool dns add 192.168.56.26 _msdcs.imanudin.com 54cab258-2d26-4273-90c1-f88397bcb5ea CNAME samba4.imanudin.com -Uadministrator
[/code]
samba4.imanudin.com merupakan nama hostname Linux Samba4

Testing hasil penambahan DNS
[code lang=’bash’]
host -t A samba4.imanudin.com
host -t CNAME 54cab258-2d26-4273-90c1-f88397bcb5ea._msdcs.imanudin.com.
[/code]

STARTING SAMBA

Untuk melakukan starting samba, dapat merujuk pada link berikut pada bagian starting Samba : https://www.imanudin.com/2013/05/13/membangun-linux-active-directory-dengan-samba4-pada-redhatcentos-part-4-compile-install-provisioning-samba-4/

Pada saat Samba4 baru saja dijalankan, kemungkinan pada log samba akan muncul warning seperti berikut :

UpdateRefs failed with WERR_DS_DRA_BAD_NC/NT code 0xc00020f8 for 5344d0a6-78a1-4758be69-66d933f1123._msdcs.imanudin.com CN=RID Manager$,CN=System,DC=imanudin,DC=com

Jalankan perintah berikut untuk solving problem diatas
[code lang=’bash’]
/usr/local/samba/bin/samba-tool drs kcc -Uadministrator windowsdc.imanudin.com
[/code]
windowsdc.imanudin.com merupakan nama hostname dari Windows Server

Check replikasi antara Windows Server DC dengan Samba 4 DC
[code lang=’bash’]
/usr/local/samba/bin/samba-tool drs showrepl
[/code]

Dari keterangan diatas tidak ada failure mengenai replikasi antara Windows Server dengan Samba4. Artikel berikutnya pembahasan mengenai Tips memindahkan GPO pada Samba4.

Silakan dicoba dan semoga bermanfaat 😀

kang,kalu sudah migrasi apakah kita harus membuat DNS sendiri di linux nya?

terimakasih

@Rahmad : Tidak hilang mas.
@Jalaludin : Jika DNS dari Windows Server tidak terambil, harus buat DNS juga di Linux-nya. Bisa dicek pada part2 😀

  Hi mas Nopriyan,
  
  Hal tersebut biasanya karena data yang ada sudah terlalu banyak (user, ou, group dll).
  Tapi pastikan saja jam antara W2k3 dan Samba4 sama (bisa pake NTP). Kemudian coba kembali

    tetap gagal mas, sudah dipastikan untuk time nya sama,,dikarenakan memakai ntp yang sama.
    
    untuk user memang banyak hampir 500.
    
    apa memang ada batasan user untuk migrasi??

      Untuk batasan Migrasi seharusnya tidak ada

  Hi mas Ruben,
  
  Secara umum, jika tidak join domain cukup buat saja si Samba sebagai file share kemudian pindahkan data2nya.

      Bisa dibuka via vi ataupun nano file /etc/hosts nya. Contoh isinya seperti ini
