FreeTDS does work with MS SQL Server, but it has problems with Unicode
and is not (yet) reliable enough to use in production.

mxODBC works with FreeTDS on Linux and most other Unix platforms,
but due to the above issues we have chosen to develop a new product
called "mxODBC Connect" which allows you to use the client driver on
the server side, rather than on the client side.

For MS SQL Server you can then rely on use the very stable and
performant SQL Server Native Client to interface directly
to the SQL Server kernel via shared memory.
