autocomplete not work

Hi All,
my customer ask me to enable the autocomplete feature on the login form to save the username credential with Internet Explorer.

I've remove AUTOCOMPLETE=OFF on the login.jsp in the form section:


<form name="IDPLogin" enctype="application/x-www-form-urlencoded" method
="POST" action="<%= (String) request.getAttribute("url") %>" AUTOCOMPLETE="off">

but it still not work.

Do you know I can enable this feature?

Thanks in advance.

Maurizio
