On Windows systems, if Teradata Database user password expires, Teradata Database returns an error message. ODBC driver detects the error and prompts for a new password (if Quiet Mode is OFF). At this point, the user is not allowed to enter another Teradata Wallet string, but must type a new password for the actual database user.
Similarly, the value for PWD2 in a connection-string cannot be a Teradata Wallet string.
