A method and mechanism for verifying information on a managed device is provided. A request identifying the managed object and also containing a plurality of non-null values comprising proposals for a correct value of the managed object is received from a requester that does not have a correct value for a managed object of a managed device. The requester is unable to read and write the managed object directly, and unable to obtain object specification information. It is determined whether any of the values match the correct value stored in the managed object. Execution of the request is completed by transmitting a notification message indicating whether any of the values match the correct value of the managed object, where the notification message does not provide any indication of which proposed value is the correct value.
