[Zope] Emergency user not working?

[ed nospam]

Hi I have zope-2.7.2 installed but I can't seem to log into zope with
the emergency user. I followed the instruction:
cd /usr/lib/zope
bin/zpasswd.py access
Username: superuser
Password:
Verify password:

Please choose a format from:

SHA - SHA-1 hashed password (default)
CRYPT - UNIX-style crypt password
CLEARTEXT - no protection

Encoding:
Domain restrictions:

and then I did /etc/init.d/zope restart but I still cannot log into zope. 

Am I doing anything wrong here?
Thank you
