Azure Connect Sync

Posted on 2016-08-23
Last Modified: 2016-08-31
Right now I have a corporate office 365 setup with about 2000 users. I need to be able to authenticate locally now with these users. My understanding is that the only way I can do this is use azure connect to sync the users locally and then sync them back up and match them up to office 365. First of all is this correct?  

Second... If I only want to sync a subset of the 2000 users (around 400 or so) what happens to the other 1600?  Can azure connect be set up to ignore the mismatch and just leave the other accounts on office 365 without touching them?

The sync process is one-way only, you cannot sync users from Azure AD to on-prem AD if that's what you're after. You can export the user details via PowerShell or similar and import them in AD, but the sync tools will not help you with this process.

As for the filtering part, you can configure it in few different ways and only include the accounts you need. The rest will remain "untouched" in Azure AD.

Yes I know I would have to export and then import them in and sync back to office 365 to have them in both places.  I was just talking to someone and they said you can join local computers directly to the azure ad domain without even having a local domain?  Then I might not even need to sync at all. I am just setting up a local domain for authentication purposes and group policy. Nothing else.

If I do end up having to do this do I need to do anything special so the accounts in azure ad remain untouched or is that the default?

Thank you for your help.

Azure AD Join is quite different compared to "traditional AD", and I can guarantee you that you will run into tons of issues with managing 2000 PCs with it. There are no OUs, no GPOs, nothing. There are many articles that explain the differences, I suggest you review few of those before making a decision you will later regret :)

Do I have to do anything special to make sure that the ad connect doesn't remove any of my extra accounts in azure ad?  I am only going to sync maybe 400 out of 2000 total accounts.

Also I don't have anywhere close to 2000 computers. It is more like 40 shared computers but I also want to have a terminal server and that doesn't seem like it will work well with azure ad join.

Sync will not remove any existing O365 accounts, however once you activate it and "match" the on-prem user objects with the Azure AD ones, every change you make on-prem will be replicated, including deleting users.

One more question related to this.  I did this and it worked properly.  But then I "upgraded" to using ADFS and when I go to Office 365 it automatically directs me to the ADFS password page even for the users who I did not migrate.  I assume there is no way around this, right?  ADFS is an all or nothing?  I had to turn it off because of this and now Office activations are quite annoying.  Thank you for your help!

It's on the domain level, yes.
