I am trying to implement JBoss Federated SSO using the standard Tomcat loginConfig.xml and JAAS. I have a Stacked login configuration, that uses the standard LdapLoginModule to authenticate, and a simple database sql select to obtain the roles. I am trying to use the standard Seam RuleBasedIdentity to accomplish the login. This works fine in a non SSO environment. What I have not been able to do is implement an SSO environment. The Seam RuleBasedIdentity does so much for me, I don't want to completely abandon it. Does anyone have a suggestion or example as to how to implement Federated SSO via a Seam RuleBasedIdentity?
