In May of 2009, we began the process of adding Macs to our Active Directory in order to give our Technical and Creative Arts people the ability to view our network shares and have more of the same privileges that users in our Windows network enjoy.

There are several ways you can accomplish this:

  • Extend the Active Directory Schema
  • Use a 3rd party product like ADmitMac or Likewise
  • The “Magic Triangle” or what Apple prefers to call the “Dual Directory” method.

My team and I discussed the various methods and I also discussed them with some other churches who integrated their Macs and we decided to use the third “Dual Directory” option (Dual Directory=Active Directory (Windows)+Open Directory (Mac).  We used a combination of both links to PDFs in Jason M Lee’s blog to accomplish this (thanks Jason!).

Here is why we chose this option:

  • Both the paid and volunteer IT Staff at our church is part time, so we need to keep as much as possible with best practices.  This eliminated the option for extending the Active Directory Schema.
  • By the time we paid for a 3rd party product for existing church-owned Macs, we could have spent the same amount on a Mac Server.  If we had gone with a 3rd party product, it would have needed to have been software that could have provided support, since our limited staffing resources would make it difficult to troubleshoot.
  • Technical Arts wants to eventually go with a Final Cut Server, so having an existing Open Directory would likely make that an easier move in the future.
  • We also wanted to push software updates, antivirus updates to the Mac clients.

Each church I spoke with had varying reasons for the method they chose.  Some are using the 3rd party product and their reasons make sense.  I didn’t find a church that chose to extend the Schema, which makes me nervous because it could potentially add some problems we might not be able to solve.

How the project went:

We used a Leopard Server and a couple of iMacs running Leopard to start.  We agreed with the Technical Arts people that we would only use Intel Macs in the Domain to keep things simple and that users should not have local admin rights since it is a lot easier to accidentally pull a Mac off the network than it is with a Windows machine.

On the server end, I think we needed our Active Directory to be at the 2008 level, but I can’t remember if that is 100% true, it seems that Microsoft made some modifications that made the process better with a 2008 Domain.

My team went through both of Jason’s links and were able to have our first Mac client in our domain in two Wednesday nights (my volunteers serve on Wednesday evenings).

We encountered our first hiccup about two weeks after our integration began because our Technical Arts Director began upgrading Macs to Snow Leopard.  That broke any Mac already on the Domain and prevented us from successfully adding new Macs to the domain until Apple released a software update several weeks later.
