Partner non admins are not authorized to sign in

I just deployed the portal and get this message:
Partner non admins are not authorized to sign in

What does this mean?

By the way, this blog post is gone:

It seems like only users with the AD Role "Company Administrator" are allowed to administrer the portal. Since the Sales department are to configure the portal it would be really nice to have another role or group to access the Admin part of the application.
