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 x64\SSO\ path in system directory.
I an confused why this is not working for Sql Server 2008 R2 and Denali.
Try by placing the ntlmauth.dll file in the bin folder of your Java Runtime Environment (e.g. C:\Program Files\Java\jre7\bin).
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.
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-dist\x64\SSO
The above directory would then contain the ntlmauth.dll file
In addition to DeChrist's response, I had to add the same dll file in the bin folder of C:\Program Files\Java\jdk1.8.0_91\jre\bin also. In that case, it worked for me.
