I read this from the 3.5 Instalation guide as one of the improvements,
where can i find the windows software mentioned and details to install?
Please help.

"The Password Management UI has changed from using portlets to using
JSPs. Identity Manager also provides software that can be installed on
Microsoft Windows*, or that can be added to the Novell Client™ login to
provide a way for end users to reset their passwords. A button appears in
the login window, which starts a restricted browser. Using this browser,
users can authenticate by using the challenge/response authentication
method. Once authenticated, users can reset passwords."
