Enable Kerberos authentication for the Reuters Marketfeed input and output adapters
      by setting the necessary environment variables and specifying the -G option.
Prerequisites
Ensure you have a 32-bit version of Kerberos installed in the machine as the Reuters
         Marketfeed adapter does not work with 64-bit versions.
 
Task- Set the following environment variables:
- Set the ESP_SERVICE_NAME environment variable  to set the service principal name.
 
- Set the ESP_GSSAPI_LIB environment variable  to point to the shared library provided by
							the Kerberos install. The library contains the GSSAPI function
							implementations. 
 
							Note: If using a Kerberos library that depends on additional libraries, set the PATH
								environment variable for Windows or the LD_LIBRARY_PATH environment
								variable for Solaris and Linux. 
						  
- Set the KRB5CCNAME environment variable  to point to the ticket cache.
 
- Set the KRB5_CONFIG environment variable to point to the configuration file used by the
							Kerberos library.
 
 
- Specify the -G option.
