Question

I am trying to connect Sql Server Data Base using windows authentication from my application using JTDS driver but i got following error

SSO Failed: Native SSPI library not loaded. Check the java.library.path system property.

Following are the scenarios where i tried to resolve but still something is missing..

i have added ntlmauth.dll in system directory and it works fine for Sql server 2005.
But the same thing i tried for Sql Server 2008 R2 and Denali but it gives me the same error as i mentioned above
Also i considered bit i mean i copied ntlmauth.dll from x64SSO path in system directory.

I an confused why this is not working for Sql Server 2008 R2 and Denali.

Answer 1

Try by placing the ntlmauth.dll file in the bin folder of your Java Runtime Environment (e.g. C:Program FilesJavajre7in).

Be sure to match the "bitness" (32 bit or 64 bit) of the DLL with the JVM bitness.

I ran into the same issue using SQL Server Express 2008 R2 and this MSDN SQL Server Forum Article recommended this resolution, which worked for me.

Answer 2

Apart from putting it into your JRE directly, you can also just specify the java.library.path as such:

-Djava.library.path=C:jtds-1.3.1-distx64SSO

The above directory would then contain the ntlmauth.dll file

Answer 3

In addition to DeChrist s response, I had to add the same dll file in the bin folder of C:Program FilesJavajdk1.8.0_91jrein also. In that case, it worked for me.
