Sql Server - connect with windows authentication

i must connect to a sql server with windows authentication

sql server is on machine 192.168.3.6 web server (client) is on my machine 192.168.3.10

I'm using JTDS driver

dbUrl=jdbc:jtds:sqlserver://192.168.3.6:1099/db_test;instance=test
Connection con = DriverManager.getConnection( dbUrl, "", "" );

I have username and password of administrator user of sql server !

I also put ntlmauth.dll into c:\windows and c:\windows\system32 and I have always error:

java.sq开发者_如何学Gol.SQLException: Login failed for user '(null)'. Reason: Not associated with a trusted SQL Server connection.

Any idea to solve my problem ? Thank you very much

See jTDS FAQ http://jtds.sourceforge.net/faq.html

you will have to pass useNTLMv2=true and domain=yourdomain

What you can do is something like:

String url = "jdbc:jtds:sqlserver://MYPC/MYDB;instance=SQLEXPRESS";
Class.forName("net.sourceforge.jtds.jdbc.Driver");
Connection conn = DriverManager.getConnection(url);

Make sure you have jtds.jar in the Java build path.

Also, add "-Djava.library.path="PATH\JTDS\x64\SSO" where 'Path' is where your SSO folder is after installing the JTDS driver (this is where you have your ntlmauth.dll).

Here is a short step-by-step guide showing how to connect to SQL Server using jTDS (as well as JDBC) with Windows authentication should you need more details. Hope it helps!
