Configuring Hybrid Join for Azure AD to Point to Specific OU
Question
Hi All,
Was wanting to turn on hybrid join for azure ad. Is there a way to point that directly to one specific OU. So we don’t contaminate all of the on prem ad. If anyone can point me to the correct article I would be greatly appreciate.

create an OU, azure ad connect, sync only that OU, drop pc’s in. I’d put block In heritence on that OU too.

Yes you can filter to a single OU.

You can select particular OUs to sync to Entra ID. I wouldn’t consider this “contaminating” on prem AD though. These computer objects are still on prem AD computer objects.

Yes possible and always first step is to go with specific OU

Google azure ad connect. Download app and setup with your OU. And enable OU when needed.

What do you mean by “contaminate”? There is no downside to Hybrid Join. The users never know it happens and it exposes more information to IT when computers are not on a local connection.

Mike Leach have approximately 2k pcs on a business that runs 24/7. I want to test hybrid join on one ou and a few pcs, before I potentially crash every pc within the company. I find it difficult that I have to explain this to fellow IT people. I’m prior military I test, test and re-test. I just don’t jump in head first into something. And there are many downsides to hybrid join. Please google and you will see people’s frustrations with it.

Matthew Salisbury Many downsides? I’ve joined thousands and thousands to Hybrid Join for my clients over the years. Never seen any major issues. Did it 2 days ago for my current client. You made it sound like that was your permanent state and not a test. So, I was trying to help. Nothing wrong with testing first. I didn’t understand what you meant by “contaminate”. But, yes, you can limit it in Entra ID Connect to specific OUs.
