AD to AD Object Sync (inc password + continuous)


Internal Windows 2008 R2 (FFL/DFL) AD
Internal Windows 2012 R2 (FFL/DFL) AD
No trust (could potentially exist)

External OpenLDAP

I have a requirement to provide a continuous object (user+group) sync from multiple ldap sources (mostly AD but a single instance of OpenLDAP).

There are currently no trusts between these directories so I was hoping to get some guidance on the following options:

1: Deploy a FIM setup
2: Create a trust a use ADMT as a object migration/merge tool (create PES for passwords)
3: Use DirSync (Non Azure)
4: 3rd party tool like 'Binarytree'

I was hoping to see if there were any options I may have missed and or any preferred methods for basic user/group object sync between AD (on-prem).

Out of all of the possible options you have I would recommned using Microsoft FIM. Below is a checklist / HowTo for setting Microsoft FIM up. This is not an easy task by any means but it will be the most effective for what you are trying to accomplish.

Hi Will

Thanks for your comment. I am leaning towards FIM - I have used the DirSync previously (and FIM) - Just wondered about OpenLDAP?

Any thoughts?

I have not had a chance to use OpenLDAP so i am not sure if it can work for exactly what you are doing. However Microsoft FIM should be able to do what you are asking.

Agreed with my thinking of FIM being most appropriate (for AD anyhow), so happy to assign points. Most likely looking at a connector for OpenLDAP.
