Browser login with Windows domain login

[<stevenr () mastek com>]

Hi

I needed some pointers/links/tips from you folks on a problem. 

I have a web-based application. Is it possible to sign in a user into
the browser based application transparently based on the windows NT
domain login. By this I mean that when the user opens the browser and
types in the URL, the client machine should automatically send the user
credentials to the application. FYI, the windows domain login is
authenticated against Microsoft Active Directory.

If this is possible, can anyone point me to some sites/tutorials? I have
googled but have not come up with anything useful, hence this mail.

Are there any known vulnerabilites with this kind of approach for web
based logins?

Any help would be appreciated.

Thanks
Steve
