    Remote EJB security - JAAS

    Ferenc Nagy Newbie

      Hi!

       

      We have some problem setting up remote EJB calls with JAAS security. We have 2 separate Jboss instances, say "Server A" and "Server B".

      There is a web application deployed on "Server A", on which the user can log in using a login form, using JAAS.

      On "Server B" there is a simple war deployed containing only 1 remote EJB.

      When the user logs in to "Server A" there is a local EJB that automatically calls the remote EJB on "Server B".

       

      The problem is that I have to know the logged in username on "Server B" in the remote EJB, so I decided to setup the server to use EJB security, to be able to automatically propagate the user principal to the server running the remote EJB.

       

      Server A

      As you can see it is a log from Jboss EAP 6.1 Alpha, but I get the same running Jboss AS 7.1.2.

       

      If I hardcode the username and the password on "Server A", the remote EJB call works works, but then I cannot get the username of the currently logged in user in the remote EJB:

      (the username is in the remote-outbound-connection tag)

      <security-realm name="ejb-security-realm">
        <server-identities>
            <secret value="YXNkX3F3ZTEyMw=="/>
        </server-identities>
      </security-realm>
      
      
      <!-- ... -->
      
      
      <subsystem xmlns="urn:jboss:domain:remoting:1.1">
                  <connector name="remoting-connector" socket-binding="remoting" security-realm="ejb-security-realm"/>
                  <outbound-connections>
                      <remote-outbound-connection name="remote-ejb-connection" outbound-socket-binding-ref="remote-ejb" username="ejbUser" security-realm="ejb-security-realm">
                          <properties>
                              <property name="SASL_POLICY_NOANONYMOUS" value="false"/>
                              <property name="SSL_ENABLED" value="false"/>
                          </properties>
                      </remote-outbound-connection>
                  </outbound-connections>
              </subsystem>
      
      

       

       

      We need the current user's name on the remote side (Server B) because we want to do some Database operations, and we have to set the "updated_by" fields of the entities. The worst solution would be adding the current user's name to every single Remote EJB call, this is not we want. If you know any other solution let me know please, the only one that I've found is using the EJB Security, but I cannot configure it correctly.

       

      Thank You for any help!
