TDS_VERSION auto doesn't try from 7.4 nor preserve bad username/password error

Hi,

We accidentally found in your source code that the TDS_VERSIONs are defined in src/tds/config.c, 7.4 as the latest. However in src/tds/login.c, if TDS_VERSION is set to auto it started guessing TDS version from 7.3, not 7.4!

                /*
                * A major version of 0 means try to guess the TDS version.
                 * We try them in an order that should work.
                 */
                const static TDS_USMALLINT versions[] =
                                { 0x703
                                , 0x702
                                , 0x701
                                , 0x700
                                , 0x500
                                , 0x402
                                };

Why doesn't it start guessing from tds version 7.4?

Meanwhile, when connecting with TDS_VERSION "auto", the bad username/password error is not preserved. It just gave an unknown error. Does the team have a plan to make this particular error more clear, i.e. preserve the bad username/password error?

Thanks,
Johnny
