FIM Bug for multi-valued strings that need approval
I think I found a bug in FIM Version 4.0.3576.2 take a look: It appears that when you have a multi-valued string attribute when you add more than 1 value at a time and you need approval to create the object or to update the attribute, the request will fail. In the event log you will see an error (UnwillingToPerformException … CREATE UNIQUE INDEX statement terminated because a duplicate key was found for the object).
