Minor patch for snmp trap auth...

[Michael Alan Dorman]

I made the following change to my copy of mon---I think it does what
is intended, that auth.cf includes a crypted copy of the desired
community string, which is then compared against a copy of the
recieved community string crypted using the same salt.

Maybe now I'll figure out how to generate the actual traps...
