IDS 7.31

We occasionally get this error in online.log.

11:56:29 Password Validation for user [abc] failed!
11:56:29 Check for password aging/account lock-out.
11:56:29 listener-thread: err = -952: oserr = 0: errstr = abc: User (abc)'s
password is not correct for the database server.

I would like to pro actively find this error before the user
gets it. My only trouble is how to simulate this error condition
via a cronjob script.
The easiest way would be to log in as user abc and check for this
error. However we do not know other users password.

I am thinking of using a bogus hardcoded password in my script
which is guaranteed to fail. My guess is that, even before it
finds out the password is incorrect, if the account is locked
out, the engine will return that error instead of invalid
password error. That would suffice my requirement.

Will my approach work or I am taking a wrong path.

thanks
