When using Kerberos authentication, you must provide the TeraJDBC.config security configuration file and specify its location in a Java property. The format of the TeraJDBC.config file is specified in the Teradata JDBC Driver Reference, available at https://developer.teradata.com/connectivity/reference/jdbc-driver . Specify the location of this file in the java.security.auth.login.configure property variable.
To add this property variable to the .ini file enter:
-Djava.security.auth.login.config=c:/TeraJDBC.config
where c:/TeraJDBC.config is the location of the TeraJDBC configuration file. The .ini file (TeradataStudioExpress.ini, TeradataStudio.ini, or eclipse.ini) is located in the same directory as the executable.
You must run kinit to initialize your Kerberos credential before launching the product.
