Create custom sync rule to sync DistinguishedName to Azure

Chau Le 96 Reputation points

I need to get DN value sync'd to azure somehow somehow... sync'd to some attribute, I really don't care which attribute. There are so many articles saying that you must create a CUSTOM SYNC RULE to do this... but NONE SHOWS YOU HOW TO MAKE THE CUSTOM RULE.

Can someone just show me how to make a custom sync rule to sync the Distinguishedname to maybe ExtensionAttribute15 or something?

    @Chau Le

    Thank you for reaching out to us. As per my understanding you want to sync On premise DN attribute to Azure ( by passing the value via ExtensionAttributeXX).

    I have verified this issue in my lab and I see we do sync DN value to Azure and the same can be seen from Graph Explorer, below are the screenshots for your reference.



    However I am sharing the steps of creating custom inbound sync rule as well on how to pass the DN information to ExtensionAttributeXX ( 1 to 15 ), you can use any attribute which ever is not in use.

    Note: No need to create Outbound rule here at this point, As out to AAD - User ExchangeOnline rule has ExtensionAttributeXX defined.

    Post creating the sync rule, perform initial sync to trigger the changes "Start-ADSyncSyncCycle -PolicyType Initial"



    Let me know if you have any questions or if you need any help in configuring the same, happy to assist you offline.
