Invalid data entered on command-line utilities

A known limitation is that some types of invalid data that are entered on command-line utilities do not produce an error.

If you enter a command that contains invalid data after all required options are specified, you will not receive an error message. For example, the following command contains the required options for the idsdnpw command, but the -- characters that follow the required option are invalid.
idsdnpw -p root -n -I inst1 --
Even though the -- characters are invalid, no error is returned.
