Unable to use Windows Integrated Authentication to access MS SQL Server from MID ServerIssue Background Customers can use Windows Integrated Authentication (also known as NTLM Authentication, Domain Authentication and so on: https://en.wikipedia.org/wiki/Integrated_Windows_Authentication) to run queries against an MS SQL Server via JDBC using a MID Server running on a Windows host. Problem Symptoms Some customers have seen the following error: MID Server reported error: java.sql.SQLException: com.microsoft.sqlserver.jdbc.SQLServerException: This driver is not configured for integrated authentication.

It's possible for a 32-bit MID server to be installed and working on a 64-bit host OS. If you don't know whether your MID server was installed from the 32-bit or 64-bit MID Server installer do the following to check: Go to the folder where the MID Server is installed, go into the logs directoryOpen the latest agent... log fileSearch in the log file for the string AutoUpgrade.3600 Installed You'll see something like this, note the part right at the end that indicates whether the installed MID server is x86-32 or x86-64:2019-11-20 22:01:13 (530) AutoUpgrade.3600 Installed: [mid-core.newyork-06-26-2019__patch2-09-18-2019_09-24-2019_1701.universal.universal.zip, mid-jre.madrid-12-18-2018__patch3-04-24-2019_05-03-2019_1443.windows.x86-32.zip]Example for 64-bit:11/12/19 05:03:00 (719) AutoUpgrade.3600 Installed: [mid-jre.madrid-12-18-2018__patch0-01-08-2019_01-17-2019_1433.linux.x86-64.zip, mid-core.madrid-12-18-2018__patch7a-10-01-2019_10-03-2019_1530.universal.universal.zip] Step 2: Verify the Java Classpath and Library Path Variables are Correct If the above doesn't resolve the issue try these steps: In \agent\conf\wrapper-override.conf or wrapper.conf (preferred wrapper-override.conf) file in the MID Server installation directory make sure that you have # Java Classpath (include wrapper.jar) # Add class path elements as needed starting from 1wrapper.java.classpath.1=lib/*.jarwrapper.java.classpath.2=extlib/*.jar# Java Library Path (location of Wrapper.DLL or libwrapper.so)wrapper.java.library.path.1=libwrapper.java.library.path.2=lib/%SNC_JVM_ARCH%Make sure that you have the correct version (32 or 64bit) of sqljdbc_auth.dll in the folder lib/x86-32 and lib/x86-64Make sure that you restart the mid server after any config changeVerify that the SQL server is configured to allow Integrated Authentication (https://msdn.microsoft.com/en-us/library/bsz5788z.aspx)Check the driver compatibility (https://docs.microsoft.com/en-us/sql/connect/jdbc/microsoft-jdbc-driver-for-sql-server-support-matrix?view=sql-server-2017) Step 3: Contacting Support If the issue still hasn't been resolved please raise a Case in HI with Customer Support, provide the results of the above troubleshooting steps and the following details: a) MID server OS b) JRE version c) JDBC driver jar file and version d) Full path of all occurrence of sqljdbc_auth.dll and their version info e) Extract of MID server log and wrapper log where the error happened.
