Hi I need to understand Matching Service Attributes.
According to the user guide. it is statedas follows: Matching—When two objects are matched, the Global Unique Identifier (GUID) of the corresponding object is written to the service attribute selected to store information about matching
I migrated 2000 users recently and if I retrieved the GUID of the source domain and the Extenstion Attribute 15 of the same migrated user, I see that they are not identical:
GUID of source domain (domain A) of user X: 7a79022c-9e79-4e92-8ffb-bef0debcdeb3
ExtenstionAttribute15 of user X on target domain (Domain B): 2C02797A799E924E8FFBBEF0DEBCDEB3
I can see that part of the GUID from User X gets written to attibute15 on the target but it is not identical. I this normal ? How can I be certain that this user is the same one when I start a new migration project? (ex: Domain C -> Domain B) ?
I do not want to merge a wrong user account.
