Add example: connect using Windows Authentication

[sietse]

I spent a good while figuring out how to specify the database server
host+instance, and where to specify the Windows Domain and the user.
Solution found here, and confirmed to work with pymssql 2.1.3:

Thanks for your contribution! I've already merged it.

On which platform are you using pymssql?

Would it be useful to you to use integrates auth so there is no need to specify username nor password when calling connect()?

Hi ramiro,

Thanks for the merge, that was quick!

I use pymssql on Windows Server 2008.

I ... think that integrated auth would be useful to me? Microsoft SQL Server authentication is not something I know much about, but the Server Manager Studio seems to authenticate without me needing to enter any credentials, so I suppose that it already uses integrated auth. One big advantage: one could then deploy without needing to put the password in a configuration file or environment variable. From where this question? Can I be of assistence, for example by field testing?

(Caveat: my usual environment is Linux and PostgreSQL, so I don't know much of what is possible in Windows or what is desirable.)

Thank you so much for being part of this library's maintenance team, it has been a lot of help to me. :-)

@sietse Thanks for your reply.

Maybe you can help us testing changes introduced to the master development branch (what will become pymssql 2.2) in that front (integrates authentication). See #402, #433 and 55e9e8a

If it's possible for you to perform this testing, you can download Wheel files for your Python version+Platform architecture from https://ci.appveyor.com/project/level12/pymssql

Any feedback is helpful and welcome!
