com.microsoft.sqlserver.jdbc.SQLServerException: This driver is not configured for integrated authentication.

  • 發行項

On a Windows platform, when trying to connect to SQL Server using Integrated Authentication, you may see this exception:
    com.microsoft.sqlserver.jdbc.SQLServerException: This driver is not configured for integrated authentication.
along with the following trace message:
    com.microsoft.sqlserver.jdbc.AuthenticationJNI <clinit>
    WARNING: Failed to load the sqljdbc_auth.dll

This generally indicates that the driver can not find the appropriate sqljdbc_auth.dll in the JVM library path.  To correct the problem, please use the java.exe -D option to specify the "java.library.path" system property value.  You will want to specify the full path to the directory contain the sqljdbc_auth.dll.
    For example:  java -cp .;"c:\jdbcv1_2\sqljdbc.jar" -Djava.library.path="c:\jdbcv1_2\auth\x86" myApp

Alternatively, you can copy the sqljdbc_auth.dll to a directory in the search path (example: the local directory where you are executing your application).

Note: You may also get the same error message if the application is trying to use the incorrect architecture (x86 VS x64) version of the sqljdbc_auth.dll.  Try specifying the directory path to the other architecture.
If you are on a x64 machine running x64 OS, but the JVM you are using is the x86 version, you will need to specify and use the x86 version of the sqljdbc_auth.dll.

Some related information:
If you get the following exception:
  java.lang.UnsatisfiedLinkError: GetDNSName
This typically indicates that the application is trying to use the incorrect version (say v1.0 VS v1.1) of the sqljdbc_auth.dll.  Make sure the application is using the save version of the sqljdbc.jar and sqljdbc_auth.dll files.

    A question about this, if we have one server for SQL Server 2005 and another one for the WebServer, where must we specify the "java.library.path" system property value? On the webserver or on the SQL Server? Thank you! Adrien

    I have a particular problem with this driver. In fact, i use three webapp in the same instance of Tomcat Server. The surprise is that i can use only one webapps, the others throw the exception : com.microsoft.sqlserver.jdbc.SQLServerException: This driver is not configured for integrated authentication.

    Have you tried the steps in the blog above ie putting the sqljdbc_auth.dll to the application directory or in the JVM library path?

    Our application runs on both Windows and Linux, and we are getting the same warning about loading the sqljdbc_auth.dll on both platforms.  Installing the sqljdbc_auth.dll works great for Windows, but when we install the Linux driver we can't find an equivalent sqljdbc_auth for Linux.  Does one exist?   By the way, we tried using the sqljdbc_auth.dll in the Linux install thinking that it had the same name but was compiled for Linux, but it doesn't work.

    There is no version of the integrated authentication dll that will work from Linux. Currently integrated authentication is Windows only.

    jay & javed - problem may be that you have multiple sqljdbc.jar's each trying to classload sqljdbc_auth.dll, and the 2nd initialization fails. look at your installation - if you have multiple sqljdbc.jar files, combine them into a single place and see if that solves your problem.

    First, thank you for the fix. It works only when I'm running it in a class as a Java Application. But when I use the same class in a servlet, I get com.microsoft.sqlserver.jdbc.AuthenticationJNI <clinit>    WARNING: Failed to load the sqljdbc_auth.dll I have placed the sqljdbc_auth.dll file in the main project dir, which did work on a regular class but not when used with a servlet.

    I would look at how to setup the class path for your particular application server. The application servers class path may be different from your standard java vm path.

    Could someone give an example of what the connection string should look like? I notice a post above has "integratedSecurity" in the string, but it looks like it is cut off. I am setting this up in java withouth any assitance, so a more complete example would be helpful.

    Hey jagooch, Does this work for you? Please notice that I'm assuming you're using a local instance, please change this information as appropriate. Connection conn = DriverManager.getConnection("jdbc:sqlserver://;serverName=localhost;integratedSecurity=true;database=archive"); HTH

    I have tried every possible solution listed in hundreds of sites with no luck. I can log in with the same credentials through SSMSE with no problem. If I use integratedSecurity=false; then I get "This user is not associated with a trusted SQL Server connection". If I use integratedSecurity=true; then I get the following: May 8, 2009 6:42:24 PM com.microsoft.sqlserver.jdbc.SQLServerConnection SSPIData WARNING: ConnectionID:1 Authentication failed code-2146893052 May 8, 2009 6:42:26 PM com.microsoft.sqlserver.jdbc.AuthenticationJNI SNISecGenClientContext WARNING: InitializeSecurityContext failed with -2146893052{WINERR} This repeats for a few seconds and it tells me the driver is not configured for authentication. I have tried many different things. I have copies of the DLL located in many different areas with no changes to these errors. Any help would be great!

    Never mind! My SQL install was not mixed authentication. I used VPN to another server and had no problems with logging in.

    Gundala, Have you tried the tips above? Are you on Windows? Try to copy the sqljdbc_auth.dll to a directory in the local directory where you are executing your application. See if you still receive your error. -- Tres London [SQL Server]

    I ran into this same issue and the short answer was as follows:

  1. Download the latest driver
  2. Install as per Microsoft Instructions
  3. Open PA Database Connection Manager
  4. Click on JDBC Drivers...
  5. Add new copy propertys from SQL Server 2008
  6. Click on Add Jar... and select the above installed file (from M$).
  7. Click on old driver and click Remove Jar
  8. Test (worked fine after this).

    I am trying to connect to SQL server 2008 from within Eclipse. However, I keep getting the message "failed to load sqljdbc_auth.dll. I have this file set in the system Path, eclipse path. The file has been copied to multiple system and application folders, but to no good. Can somebody suggest me steps one by one to configure Eclipse to log on to SQL server 2008? Thanks Raghu

    I Microsoft SQL Server JDBC Driver 3.0 on a client machine running WIn7 64bit and I am using Window Server 2008. I am using NT authentication.  Sometimes I get connected to the database with no problem other times I get the following intermittent error: com.microsoft.sqlserver.jdbc.SQLServerConnection SSPIData WARNING: ConnectionID:46 Authentication failed code-2146892976 with the message "This driver is not configured for integrated authentication" Inevitably I reboot the client machine or restart the client application, which seems to increase the odds of a connection being established. jdbc:sqlserver://<my sql server IP address>;database=qai;integratedSecurity=true; Not sure why? Is this just related to a time-out or a path issue? does anyone have any ideas? Should I force the login timeout to be longer?

    Señores: Yo trabajé con la herramienta Rational Functional Tester V.7 en base a el IDE Eclipse y realice la conexión con el MS SQL Server 2008 R2, antes que todo descargue el archivo indicado en todos los blog de MS, para la versión MS SQL Server 2008 R2  conector JDBC. 3.0 de todas formas siempre puedes usar el sqljdbc.jar, donde encontraras la .dll necesaria nombrada "sqljdbc_auth.dll", recuerda chequear la versión para tu procesador, X86(32 Bits),  64 Bits y otra extra que aparece. La mejor opción es copiar el archivo .dll Solución: C:Window y listo, estará todo Ok. Puedes realizar la prueba ahora, el String de conexión que use fue este: String url = "jdbc:sqlserver://localhost;databaseName=Mydatabase;integratedSecurity=true;"; locahost = nombre del servidor. databaseName= nombre de tu base de datos. integratedSecurity=true; indica que ingresara con la "Autenticación Window".
