Need help: Kerberos authentication for DFS application.

Hi,

I have a DFC application exposed as Web Service using the “@DfsPojoService” annotation. For authentication it is currently utilizing a custom authentication plug in which take user’s login name and a fixed text as one of the arguments aside from the login name for the ‘IDfLoginInfo’ object, like this:

loginInfo.setUser(strUserLoginName);

loginInfo.setUserArg1(strSSOID);

This web service is called by a .Net based application which passes the login name and that fixed text (say SSO ID) as the argument to the service. Now, I need to replace this authentication mechanism with Kerberos SSO, preferentially without any change at the client side (the .Net based application). It is first time I am implementing the Kerberos authentication; I gathered the basic information on Kerberos and configurations need to be done for the webtop, but the solution for DFS that too specific to my scenario I could not find or clearly understand.

May I have some lucid guideline on how do I go about it. Please let me know if you have any query which may help you understanding the scenario in a better way and guide me.

I’ll highly appreciate quick help.

Thanks,

Abhishek
