I have used single sign on(SSO) via Kerberos SPNEGO mechanism IBM Implementation in our project. SSO Via Kerberos Authentication is working fine with Tomcat server(using sun JVM). When I am using Websphere 188.8.131.52(using IBM JVM), SSO Via Kerberos Authentication is not working. Getting java.lang.NullPointerException. I searched for solution in IBM forum, couldn't find any solution for this problem.
