Hi I am new to this jboss-portal,
Currently I am working on migrating already existing portal developed with jboss-portal2.4 to jboss-portal2.6.1.
My portal is using a custom login module which extends IdentityLoginModule, as lot of changes happend to the Jboss portal Identity api in jboss-portal2.6.1 , I changed the existing code with the new api changes.
This is My Code
public class SsoLoginModule extends IdentityLoginModule
