Hi ai77, if I unterstand the docs correctly, the synchronization of the two databases can be done by the SynchronizingLoginModule (at least for the JBoss part). It is described here: http://docs.jboss.com/jbportal/v2.6.4/referenceGuide/html/authentication.... You can also turn off the Jboss IdentityModule in login-config.xml, or mark it as optional. Then you won't have to mess around with two databases (but I'm not sure what will happen to JBoss specific functions then). I already tried logging in with a user that exists in the portal database as well as on the remote server I have to authenticate to, but it's still the same problem. But you said it worked out for you, so I will give it another try. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4150710#...
