[Zope] authentication problem

hello everyone, i'm trying to try out zope's file permission and authentication on different users. i think i got the roles and users to set for each file correctly under zope manager but when i try to do "/manage" on a specific file, netscape ask me for username/password. i entered it in, but i couldn't get netscape to authenticate for that user. i added that username/passwd to the access file and still couldn't get netscape to authenticate. how do i get netscape to authenticate a different userser besides the "manager" account? thanks khai btw, i'm running zope under win95 with zope's http server
