 > [!NOTE]
 >- When using the Active Directory options with the Windows ODBC driver ***prior to*** version 17.4.2, ensure that the [Active Directory Authentication Library for SQL Server](https://go.microsoft.com/fwlink/?LinkID=513072) has been installed. When using the Linux and macOS drivers, ensure that `libcurl` has been installed. For driver version 17.2 and later, this is not an explicit dependency since it is not required for the other authentication methods or ODBC operations.
