FreeTDS

FreeTDS is an open-source implementation of the TDS (Tabular DataStream) database client access protocol and related libraries used by Sybase and Microsoft.

FreeTDS supports all versions of the protocol from both vendors, and includes DB-Lib, CT-Lib, and ODBC libraries.

What is new in this release:

• This version provides full Kerberos and SSPI support for passwordless login to Microsoft SQL Server from Unix and Windows clients.
• It fully support building DB-Library on Win32/64 via NMAKE.EXE.
• It has built-in support for UTF-8 and wide characters in ODBC and better thread-safety in ODBC, and error messages in all libraries now distinguish between connect and login errors.
• For Microsoft servers, FreeTDS implements TDS 7.2, the version used by SQL Server 2005.
