During the provisioning step of a new [[Setup_a_Samba_Active_Directory_Domain_Controller|Samba Active Directory Domain Controller]], you have decite which DNS backend, if any, should be used: The internal DNS or BIND_DLZ. In some cases, it might be necessary, to revise this decission because of problems, limitations or other reasons. In the following we describe, how to change the DNS backend on a Samba AD Domain Controller.

Samba enables you to change switch between the <code>INTERNAL_DNS</code> and <code>BIND9_DLZ</code> DNS back end on your Active Directory (AD) domain controller (DC) without loosing data.

Introduction

Samba enables you to change switch between the INTERNAL_DNS and BIND9_DLZ DNS back end on your Active Directory (AD) domain controller (DC) without loosing data.



Changing From the Samba Internal DNS Server to the BIND9_DLZ Back End

Run on your domain controller (DC):

  • Shut down the Samba service.
  • Migrate the back end:
# samba_upgradedns --dns-backend=BIND9_DLZ
  • Use one of the following ways to disable the internal DNS in your smb.conf file:
  • If you have a server services parameter, remove the dns option. For example:
server services = s3fs, rpc, nbt, wrepl, ldap, cldap, kdc, drepl, winbindd, ntp_signd, kcc, dnsupdate
  • If you do not have a server services parameter, add the following line:
server services = -dns
  • Enable the BIND service to start at boot time. See your distribution's documentation for details.
  • Start the BIND service.
  • Start the Samba service.



Changing From the BIND9_DLZ Back End to the Samba Internal DNS Server

Run on your domain controller (DC):

  • Shut down the BIND service.
  • Disable the automatic start of the BIND service at boot time. See your distribution's documentation for details.
  • Shut down the Samba service.
  • Migrate the back end:
# samba_upgradedns --dns-backend=SAMBA_INTERNAL
  • Use one of the following ways to disable the BIND9_DLZ module in your smb.conf file::


  • If you have a server services parameter, add the dns option. For example:
server services = s3fs, rpc, nbt, wrepl, ldap, cldap, kdc, drepl, winbindd, ntp_signd, kcc, dnsupdate, dns
  • If you only have the -dns option listed in the server services parameter, remove the entire parameter:
server services = -dns
  • Start the Samba service.
