We found that in order to get it to work properly, you need to set the default domain within the Kerberos configuration file, to the domain that the SQL Server resides in. If you have a multiple domain environment with SQL Servers in different domains that you are trying to hit, you will run into issues.
#MYSQL JDBC DRIVER FOR SPARK HOW TO#
It walks through how to create the keytab files and what to do with the krb5.ini file.Ĭonfigure Kerberos with Weblogic Server (really just a Java reference) It indicates Weblogic, but really it just goes through the java aspects. The following blog does a good job of walking through the steps to get this setup for Java. Assuming all of that is in place, the driver should work using JavaKerberos to connect. If you need to use a different Login Module, you will need to make sure that is configured for your environment. If you don’t have one, the driver will automatically configure it using the Krb5LoginModule. A login configuration file also needs to be setup. You will also need to generate keytab files for the platform to reference.

In the above referenced documentation we have a sample of what that should look like.

After that is done, you will need to make sure that the Kerberos Configuration file (krb5.ini or nf) is configured properly on your platform. So, you will need to make sure your driver is updated to the 4.0 driver or later. This will not honor the JavaKerberos setting and you will get the error listed above. Using Kerberos Integrated Authentication to Connect to SQL ServerĪnother aspect that was discovered was the that it appears that the WebSphere 8.5 release comes with the 3.0 version of the SQL JDBC Driver. The following document outlines how to use Kerberos with the JDBC Driver and walks through what is needed to get JavaKerberos working properly.

In the third case, even if you specify authenticationScheme=JavaKerberos, it won’t help as the older drivers aren’t aware of it, so it is ignored. , you are using a version of the JDBC Driver prior to the 4.0 driver and trying to use Integrated Authentication on a Unix/Linux platform. , you specified integratedSecurity and omitted authenticationScheme, which defaulted to NativeAuthentication, and you are on a Unix/Linux Platform. , you actually specified authenticationScheme=NativeAuthentication in your connection string and you are on a Linux Platform.

So, if you are receiving the error above, there are three possibilities that could be causing it to show up.
#MYSQL JDBC DRIVER FOR SPARK WINDOWS#
This is java specific and not bound to the underlying operating system, so this can be used on both Windows and Linux platforms. – Makes use of the Java API’s to invoke kerberos and does not rely on the Windows Platform. This was the only option prior to the JDBC 4.0 driver. (default) – This uses the sqljdbc_auth.dll and is specific to the Windows platform. Starting in the JDBC 4.0 driver, you can use the authenticationScheme connection property to indicate how you want to use Kerberos to connect to SQL. It is when we are trying to use Kerberos and the Authentication Scheme is set to NativeAuthentication, which is the default setting for this property. There is only one location within the JDBC Driver where this particular error is raised. The last one I worked on was running WebSphere 8.5. Specifically they were running WebSphere on a Linux platform. The key environment point on this was that they were trying to do this on a Linux platorm and not a Windows platform. : This driver is not configured for integrated authentication I’ve had about 4 cases in the last two months that centered around the following error when trying to use Windows Integrated authentication with JDBC.
