Accoring to the CIM guide at http://www.authorize.net/support/CIM_XML_guide.pdf PAGE 105 under "Duplicate Profile Verification",  when adding a new payment profile using "createCustomerPaymentProfileRequest", if the payment profile information is the same as a payment profile already in the customer profile, "then the payment gateway will return an error that contains the ID of the already-created profile." As far as I've been able to test, it does not work like the documentation states at all. All I receive back is "Error E00039 A duplicate customer payment profile already exists.", but I do not receive the crucial payment ID of the existing matching profile.

I absolutely need to get this existing payment id returned as there is no other way for me to compare newly entered CC info to a customer's existing profile because all CC info is masked out. (Customers do not [yet] store profiles in my system, but on certain recurring delivery orders, I first bill using AIM for the 1st transaction, then store their info in a CIM profile for subsequent transactions. If a customer returns and starts another recurring delivery order, they enter their CC info again, it will be billed via AIM, then go to CIM. If the payment already exists, I want to use the existing payment ID. If not, create a new payment profile.)
