[Zope] zope not authorizing

[Rajil Saraswat]

i installed the zope-pcgi rpm file. the default user is superuser and
password is 123. but when i give these values in the prompt, the software
does not authorize me. i also changed the access file in /var/zope using
zpasswd but still the login is not working. 
earlier i was using zserver and it was working fine, is there some problem
with pcgi, is there some changes to be made. i did all the changes as
given on the rpm page at zope.org(httpd file change)
however when i goto http://localhost/static the zope screen is not
displayed. but if i goto http://localhost/cgi-bin/Zope.cgi then the
welcome screen comes. but i am not able to authorize myself at the
auth. prompt.
using pcgi what is the default object url, will it be
http://localhost/Zope.cgi/sample. if this is the case can we change it to
http://localhost/sample. 
basically i want the zope root to be located on http://localhost instead
of obscure url like http://localhost:8080 or
http://localhost/cgi-bin/Zope.cgi. This was the reason i wanted to try out
pcgi. can we do this.
please help!!
