[AGENT++] Wrong exeption in GET-response to unavailable object instance

[Fehde, Marcus]

Hi,
 
may be I discovered a non-compliance to RFC 3416 regarding the exception in case of an unavailable object instance.
Example:
An GET-request to 1.3.6.1.2.1.1.1.0 works as expected.
An GET-request to 1.3.6.1.2.1.1.1 result in a "no-such-name" exception as well as
an GET-requesz to 1.3.6.1.2.1.1.1.1.
 
Accordingly to RFC3416 the correct result would be an "no-such-instance" exception:
 
RFC3416 (SNMPv2); pp. 10-11 states:
"Upon receipt of a GetRequest-PDU, the receiving SNMP entity 
processes each variable binding in the variable-binding list 
to produce a Response-PDU.  All fields of the Response-PDU 
have the same values as the corresponding fields of the 
received request except as indicated below.  Each variable 
binding is processed as follows:
   
...
   
(2)  Otherwise, if the variable binding's name does not have an
  OBJECT IDENTIFIER prefix which exactly matches the OBJECT
  IDENTIFIER prefix of any (potential) variable accessible by
  this request, then its value field is set to "noSuchObject".
   
  (3)  Otherwise, the variable binding's value field is set to
  "noSuchInstance".

Please, can someone verify this.
