I've done this:
UserTarget target = new UserTarget();
target.setSecurityName(new OctetString("CryptoExtWeb"));
Then I've done this:
UsmUser user = new UsmUser(new OctetString("CryptoExtWeb"), null, null,
null, null);
In this way the code works fine and the trap is sent but if I use
different OctetStrings this runtime exception is returned.

So I've deduced that the two OctetStrings must be equal.
