What settings are required to connect to SharePoint via the Office Hub on Windows Phone 7? I've heard so many contradictory things that I have no idea what it takes. Is it using claims auth? classic auth, while on an intranet?
Currently the web application needs to support anonymous or forms-based authentication (which requires claims), because Windows Phone 7 does not support Windows authentication. I think you can also use Basic authentication but wouldn't recommend it.
There are ways to implement FBA so that the credentials map to AD using an LDAP authentication provider.
The Microsoft recommended solution, for an intranet situation, is to use Forefront UAG if possible. This translates from FBA to Windows so you don't need to do a lot of work on your SharePoint configuration. But of course you have to implement (and pay for) UAG.
This may well all change with the Mango release in late 2011. I think a lot of people will be waiting for an update to WP7 to support Windows authentication rather than try to get it working.
