This really is astounding great news. I almost can't believe it. Thanks
freddy77. JKL asked if I wanted to take a stab at this problem, but you
chopped off its head before I could even think about it.

I built freetds-0.83.dev.20100127 in mingw-cross-env with this
configuration:

./configure \
        --prefix='$(PREFIX)/$(TARGET)' \
        --host='$(TARGET)' \
        --disable-rpath \
        --disable-dependency-tracking \
        --disable-shared \
        --enable-sspi \
        --enable-static \
        --enable-libiconv \
        --enable-msdblib \
        --with-tdsver=8.0

Don't forget "--enable-sspi"!

First I tried jkl's test with bsqldb.exe. It works!

Then I rebuilt the Qt TDS driver plugin in mingw-cross-env and tried it
in an app in Win7. It works! No password!

Thanks. I'm going to go celebrate.
