It sounds like you are querying the SNMP server for an OID that you have 
not exposed to be viewed by the read only snmp v1 user. Make sure the 
following two lines exist (and look the same) in your snmpd.conf:

view  all  included      .1
access notConfigGroup "" any noauth exact  all    none   none
                                            ^^^
			       note "all" must be present

Yes, the above advice is important. If your application support it, then 
definitely try and use SNMPv3.
