[Zope] newbie, Help with managment login

Hi everyone I just grabed the latest Zope rpms , it seems to work fine , I get to the "welcome to Zope!" page and the QuickStart pages work , but when I try to access the managment screens I allways get Authorization error? I am using RedHat6.1 and have tried using Apache and Zserver and get the same error with both? I have tried changing the username and password in the access file. There must be some thing simple that I am missing? Thanks , Stephen
