Hi.

I'm building this iPhone application to connect to a secured TFS server (one that requires authentication before letting you access its web services). When I access this server in a browser, the first thing it will do is ask me for credentials (username/password) and then connect me to the TFS server if those credentials are correct.

I am using web services, as I don't think there is any other way to use TFS functionality for an outside platform...without changing stuff on the TFS host machine. So my questions are:

• Are there any web services that can be accessed to log into the TFS server?
• This authentication mechanism seems to be something common among multiple websites (I have seen it in other websites). Is there a way to replicate that authentication mechanism by sending an HTTP request?
• Is there a way to replicate this authentication procedure in any way?

Thanks!
