newbie question please respond

[sarath]

i am trying to design and implement an SSO for web applications,in
Java, using
JAAS, Kerberos 5 and GSS for java. The problem is each of them is new
for me.

I have downloaded some sample code from

http://www-128.ibm.com/developerworks/java/library/j-gss-sso/

it assumes that the system is windows 2000 and belonging to some domain
in a server.

i am not in any domain.

i am not able to start anything right now.. please give me some
pointers in the right direction

Thanks in advance.
