I am using pentaho data integration 4.1 (Kettle) to build an ETL system. My customer requires connecting to database (MS SQL Server) using window authentication, I knew that Kettle supported it . However when I run my Kettle job, it throws the exception

"I/O Error: SSO Failed: SSPI Not Initialized".

From an article on a forum, I copy library sqljdbc_auth.dll into jre/bin folder. The result is quite good, I can use window authentication to connect to SQL server. But this function is not stable, I mean sometimes it works well, sometimes it throws exception

"I/O Error: SSO Failed: SSPI Not Initialized".

Please tell me how to fix this error.

Thank you.

    To connect to SQL Server 2008, I had to install the ‘Microsoft JDBC Driver 4.0 for SQL Server’ and then add the path to sqljdbc_auth.dll to Spoon.bat in %PENTAHO_DI_JAVA_OPTIONS%. Like this:

    set OPT=%PENTAHO_DI_JAVA_OPTIONS% "-Djava.library.path=%LIBSPATH%;C:\PROGRA~1\MICROS~1.0FO\sqljdbc_4.0\enu\auth\x86;C:\PROGRA~1\IBM\SQLLIB\BIN" "-DKETTLE_HOME=%KETTLE_HOME%" "-DKETTLE_REPOSITORY=%KETTLE_REPOSITORY%" "-DKETTLE_USER=%KETTLE_USER%" "-DKETTLE_PASSWORD=%KETTLE_PASSWORD%" "-DKETTLE_PLUGIN_PACKAGES=%KETTLE_PLUGIN_PACKAGES%" "-DKETTLE_LOG_SIZE_LIMIT=%KETTLE_LOG_SIZE_LIMIT%"

    Ugly, but that’s Java under Windows for you. Works quite reliably now though.
