I/O Error: SSO Failed: Native SSPI Library not Loaded

When this error is encountered, it is because a process is seeking to use your windows credentials to connect to a Microsoft SQL Server.  When a Java application using jDTS attempts  a Single Signon to MS SQL Serve, a library is needed on the machine.  This is the ntlmauth.dll library which is often missing when you move your code from development to production.

This file must exist in the system’s path.  When on a Windows system, a good place to put it is in the Windows\System32 folder.
The library is available for download from the jDTS project at the following address: jDTS Project – Downloads
