SAP Gui Single Sign-On with Kerberos


I am working on the SAP GUI SSO with Kerberos. We have decided to use SAP NW-SSO Secure library to support the Kerberos.
I am following the instruction from SDN Link -

1.     Create Service Id and SPN

2.     Setup SAP Parameters

3.     Setup SAP SNC Parameters

4.     Setup KeyTab

5.     Restarted.. SNC is on with Service ID and I can confirm it is working from dev_wx trace.

We setup SNC parameters in User master record and Gui properties. But when I click to log-on , we get the error message " GSS-API(maj): No credentials were supplied. Unable to establish the security context. "

I am doing this on my POC environment.  With that being said, my Window machine is setup with same domain but my SAP environment on productive domain. Do you see this an issue?

I have attached the error message received.

Did I missed anything?

Thank you in advance.
