Enable Kerberos authentication for the KDB input and output adapters by setting the necessary environment variables and specifying the Authentication and espUser parameters.

1. Set the following environment variables:

   3. Set the KRB5CCNAME environment variable to point to the ticket cache.
   4. Set the KRB5_CONFIG environment variable to point to the configuration file used by the Kerberos library.
2. Specify the following parameters:
   • Set the Authentication parameter to kerberos.
   • Set the espUser parameter.
