OAM-AD integration: Different beavior of OVD and OID

Hi,

we have similar system topology that described in this use case:

http://www.ateam-oracle.com/part-1-under-the-covers-of-oam11g-wna-integration-with-multiple-ad-forests/

but instead OVD, we are using OID.

AD and OID Accounts will be synchronized.

My question: What is behavior of OID at step 13? Does OID search AD Domain or search same OID-Entities? How can I exact check and/or configure this step?

Thanks,

Moh
