Re: v3 traps and plain text password

If I have two usmUser entries in the configuration file, then how to specify
which user to use when sending traps to a particular destination.
To do this, we need to specify the user name in  "trapsess .." line in the
configuration. Here we will end up giving plain text passwords for the user.
