ActiveDirectoryServicePrincipal connection string

[RudraNirvan]

The current set of examples demonstrate how to connect using only two methods:

simple: login/password
MSI token
How does one connect via the Service Principal of an application? I tried the following (and some variations of it) but it did not work:

"server=%s;user id=%s;password=%s;port=%d;database=%s;fedauth=ActiveDirectoryServicePrincipal;"
Shows this error: login error: Login failed for user

Is this issue saying that the code in your proposed example doesn't work?

[RudraNirvan]

@shueybubbles it actually does work, I was passing the parameters incorrectly. Therefore, created that PR to demonstrate a working example in case someone else wants to try "ActiveDirectoryServicePrincipal".

On that note, since you've renamed all the modules for this fork, I'll probably fork your fork and create new PRs if I don't get a review on denisenkom.
