Couple of notes. First, I wrote up an example for exactly this situation
on my blog some months ago:
http://weierophinney.net/matthew/archives/165-Login-and-Authentication-with-Zend-Framework.html
In that article, I suggest using the form's Description along with a
Description decorator for displaying an "invalid credentials" message.
Second, there have been requests for an error message mutator in
Zend_Form/Zend_Form_Element, and I hope to have time to do this for the
1.6 release.
