I made a try with a CSV fulfillment for AD permission, just to see attributes availability and I get this:

changeItemId,changeRequestType,fulfillmentInstruct ions,userName,account,appName,reason,permName
"19","ADD_PERMISSION_TO_USER","","John Demo","","AD Account Permissions","Add Permission to user for permission ERP_Administrators to be given to John Demo requested by John Demo. Reason for request: test; test","ERP_Administrators"

And I can see there is no account ?

Let's try now with LDAP fulfillment.
