[SNMP4J] Unsupported security model

[Kazantsev, Andrey V.]

I'm glad to hear that I helped you.

What user name do you mean? In fact there is only security name, which is first argument to UsmUser constructor. You use it later for adding this user to USM instance (usm.addUser(user.getSecurityName(), user)). I just called security name with "username", but it could be arbitrary string.

  Hello

Thanks for your quick reply. I've tried your code and after five tries 
it now works. In fact I didn't understand that the username and the 
security name have to be equals (confirm?). But now it works fine.

Thanks again for your help
Have a nice day
