Open Directory in Window Domain

We are planning to setup a OpenDirectory in Window environment and put its IP as one of the DNS leasing in DHCP service.

1. Can any window and mac workstation  use it for DNS resolution
2. Can window and mac workstation be login to the window domain in case it contact the DNS service in OpenDirectory ? OpenDirectory shouldn't be able to authenticate to Window domain so I suppose it should at least able to forward this request to my DC records.

Are you having an active Directory as well as attempting Open Directory?

Yes, just wonder whether I can use the DNS in Open Directory to offline the DNS offered by DC ? Can I  include OSX Server as DNS record in DHCP and lease to both Window and MAC workstation ?

Cris HannaSr IT Support EngineerCommented:
Windows doesn't like two DCHP servers on the same subnet.   Are you just trying to shoot for redundancy incase the Windows Server goes down?   Having both AD and Open Directory will be a nightmare in my opinion, unless you're just doing this for learning purposes, but I would never advise this in a production environment.   Are you trying to fix an issue?

no. I have one dhcp server but can I add server osx in DNS record for dhcp leasing,

can window or mac book can use it , similar to AD DNS?
Cris HannaSr IT Support EngineerCommented:
According to Wikipedia:
When connected to a directory system, a Mac OS X client or Server can authenticate users, lookup contacts, perform service discovery and name resolution with the following types of directories:[6]

Authentication and contacts
Microsoft Active Directory
LDAPv3, including an Open Directory domain or RFC 2307-compliant system
Apple/NeXT NetInfo domains
BSD flat files and NIS

What I don't get is what you think the benefit would be.  Do you have several Mac computers in your network?

OD only needs DNS for for the server, per se. when in a Golden triangle.  That being said here is how it should be setup and will work:


Since you already have AD and DNS in place, Keep it and let AD DNS manage your network


Create a DNS entry on your AD DNS server for your Mac


Make sure that your Mac is now configured with the static IP you entered into your AD DNS


Configure your Mac's DNS to point your AD DNS server and no other


Join your Mac to AD


You should now be able to configure OD
I do not recommend using two distinct DNS servers on your network and the same for DHCP.  A single point of management and implementation is the best way to go with what you ask.

Do you mean that only two Window DNS servers should be leased by DHCP. I shouldn't include the OSX server in my DNS (which also hosted the A records in my network) ?

Each MAC book will join the Window Domain and OSX server, correct ?

I did not have my Mac server host DNS records, it was left on the windows servers. If you have a primary and secondary windows DNS box, go ahead and leave in you DHCP settings.

The Mac server really doesn't care about where DNS is as long and there is DNS.
