[Zope] installation

I can't go to management screen with superuser passwd. I'm using correct name and passwd (as specified in access file), but Zope says "Unauthorized. You are not authorized to access this resource." I'm using apache. No useful info in Apache's log's, pcgi.log and zope.log. Zope.cgi has been copied to apache cgi-bin dir. Apache has correct rewrite rule configuration as per WEBSERVER.txt. This is Zope 2.0.1 rpm. I also tried Zope 2.1.1 sources with same result. Please help me... -- Milos Prudek
