### Azure Active Directory authentication - preview
The configuration of functionality might change in the future.
Azure Active Directory (AAD) access tokens are relatively short lived and need to be
valid when a new connection is made. Authentication is supported using a callback func that
provides a fresh and valid token using a connector:
``` golang
conn, err := mssql.NewAccessTokenConnector(
"Server=test.database.windows.net;Database=testdb",
tokenProvider)
if err != nil {
// handle errors in DSN
}
db := sql.OpenDB(conn)
```
Where `tokenProvider` is a function that returns a fresh access token or an error. None of these statements
actually trigger the retrieval of a token, this happens when the first statment is issued and a connection
is created.
