Deploying Active Directory with DNS (linux) in Mixed Environment

Deploying Active Directory with DNS (Linux) in Mixed Environment

Integrating Active Directory with the Linux as primary DNS Server Lately I was working on integrating the newly configuring Windows 2003 Active Directory with the old running DNS server which was running on Linux. After a day or two searching on the internet I finally found a way to integrate the windows and Linux together.

Generally we install DNS server into an Active Directory. The separation might have been far easier if the DNS server had been the Windows Server itself, but some tweaks were required when the server was Linux.

The Linux DNS server was far old running and the new Active Directory was to integrate to it. So the active directory was installed in the windows 2003 server with the domain name adtest.dipes.com.np and the full name of this computer being dc.adtest.dipes.com.np

The preferred dns of the server itself was like that of others and the clients, e.g. 192.168.40.2 (the ip of Linux DNS server)
The windows server (domain controller) ip was 192.168.40.13

Then inspecting the netlogon.dns file, the following lines of codes of database were written in the dns database file of Linux (dipes.com.np zone file)


dc.adtest IN A 192.168.40.13

_ldap._tcp.adtest.dipes.com.np. SRV 0 0 389 dc.adtest.dipes.com.np.
_kerberos._tcp.adtest.dipes.com.np. SRV 0 0 88 dc.adtest.dipes.com.np.
_ldap._tcp.dc._msdcs.adtest.dipes.com.np. SRV 0 0 389 dc.adtest.dipes.com.np.
_kerberos._tcp.dc._msdcs.adtest.dipes.com.np. SRV 0 0 88 dc.adtest.dipes.com.np.

And this was what looked in the netlogon.dns file in windows server
adtest.dipes.com.np. 600 IN A 192.168.40.13

_ldap._tcp.Default-First-Site-Name._sites.DomainDnsZones.adtest.dipes.com.np. 600 IN SRV 0 100 389 dc.adtest.dipes.com.np.
The next step was the finally joining the client with the domain controller with its previous old settings of preferred dns being same (i.e. 192.168.40.2)
