Help Needed for Kerberos token retrieval using GSS API

[Aditya]

Hello Sir,

I am not sure whether this is correct forum or not but......

Can you please let me know that how can I write JDK 1.6 program to retrieve Kerberos token of the logged in user? I am very new to this technology. 
After reading few articles I am not able to understand, how I can do it at my machine(stand alone Windows XP machine).

Your inputs can help me a lot.


Regards,
Aditya
