[Zope] New kubuntu zope/plone installation problem

[Mike Elliott]

I just installed zope and plone on a new Kubuntu installation using
the Adept package manager.  Zope comes up on port 8081 -- which was a
bit of a surprise, as I expected it to be on port 9673 as in other
Debian distributions -- but I can deal with that.

The problem is I don't know the admin username and password.  Is there
a way to either find out what they are or to reset them to something
known?

Any help would be most welcome.
