UserID/Password failure when attempting a connection

I'm used to having to trap for run-time issues when trying to connect to databases. In Oracle, if I fat-finger a password and try to use it to connect, I'd get a run-time error with an Exception.Number value of 1017. There doesn't seem to be like procedure in Teredata even though I find references to an 8017 run-time error somewhere (in the Message to be sure but I'd rather not have to parse that).
What is the recommended method of trapping invalid userID/password attempts at connecting to a Teradata database?
Thanks in advance.
