how do you handle situations where the password passed to passwd will be
objected to by your passwd cracklib.

ie:
passwd username
enter old password - goodpass
enter new password - badpass
**** new password is idiotic you should be destroyed ***
enter another new password -

blah blah blah

Is there  a good way to get around this problem?
