Local Authentication when Running Xpages

I am designing an Xpages application. The design is on a server but I would like to work on it on my local machine (speed is faster). It works OK except when I need to log in. I get an authentication dialog box which looks different from the one I get on the server and it asks for my username and password for the local host. I use SSO so I give it my Notes username and password, the same one that works on the web site, but it refuses the connection.

What am I doing wrong?

Subject: Authentication

Whenever you’re authenticating, you’re authenticating against the names.nsf of the same server the database is on, so your local names.nsf, your Personal Address Book.

If I’m developing a web application (and that’s effectively what an XPages app is), I tend to work on a local copy giving Anonymous the relevant access I want to test.
