What to use "Active Directory Changes" or "Active Directory Sync Changes"?

Shane Lim 13 years ago • updated by anonymous 8 years ago • 9

My knowledge of Active Directory and Event Broker is very limited.

I have read https://unifysolutions.jira.com/wiki/display/EB300/Active+Directory+Changes and https://unifysolutions.jira.com/wiki/display/EB300/Active+Directory+Sync+Changes and understood that the later uses the Directory Synchronization Cookie method.

What I do not understand is why different method of detecting the Active Directory changes is required and when to use which method. Eg different version of Active Directory?

I would appreciate if someone could help clarifying this for me.

Thank you in advance for your time and help.

Hi Matt,

Can you please answer this and update the documentation as necessary to be clearer.

Thanks.

Shane,

The main difference is the method that is used, with Active Directory changes also able to perform tombstone detection as far as I'm aware. Adam can comment further, and we may possibly need his input in making the documentation clearer

Hi Matthew,

I found this document explaining the two method of detecting changed for Active Directory How to poll for object attribute changes in Active Directory on Windows 2000 and Windows Server 2003

You can use the following two polling methods to monitor changes in Active Directory:

  • Use the Active Directory directory synchronization (DirSync) control.
  • Use Update Sequence Number (USN) queries that use the uSNChanged attribute.

Does this corresponds to the two methods for Event Broker?

Hi Shane,

Yes, that link you provided describes the differences between the two methods.

Please assign this issue back to Matthew so that he can review our documentation on the topic.

Thanks.

Re-assigned to Matthew as per Adam's request so.

Updated documentation with more information on each operation. Assigned to Adam to confirm if it is clear (and correct) in the documentation what the difference is between the two
