[SNMP4J] reg: USM and MPV3

[satish gummadelli]

Hi Frank,
Thanks for your reply.

we have 2 NMS systems,
Our Requirement is , each NMS can configure its own engine id and usernames.
we have multi threaded program which works perfect for one NMS.
after adding a new NMS we are using the same snmp session object with the
different USM [which has different username and local engine ids] to send
the PDU.

Reason why we are adding different USMs are ... because of different
usernames and engine ids.

I have debugged the code and found that .. USM is giving security name not
found and it returns null in USM.getUser() method.

our requirement is to have different multiple USMs for one session to send
the PDUs.
