-----------------------------------

I've something like this in mind:

{code:xml}
<jboss-ejb-client xmlns="urn:jboss:ejb-client:1.0">
    <client-context>
        <ejb-receivers exclude-local-receiver="true">
            <remoting-ejb-receiver outbound-connection-ref="abc" />
        </ejb-receivers>
        <clusters>
             <!-- Configuration for cluster named ejb -->
             <cluster name="ejb" max-allowed-connected-nodes="5" username="foo" security-realm="realm configured in domain or standalone config" connect-timeout="5000">
                <!-- Optional cluster node selector -->
                <cluster-node-selector name="org.myapp.Foo" module="optional-module-name"/>
                <!-- Connection creation options applicable to all nodes in this cluster -->
                <connection-creation-options>
                    <property name="prop" value="val"/>     
                </connection-creation-options>
                <!-- Optional channel creation options -->
                <channel-creation-options>
                      <property name="prop" value="val"/>
                </channel-creation-options>
                <!-- Optional node configurations for a specific node in this cluster -->
                <node name="some node name" user-name="foo" security-realm="bar">
                    <!-- Connection creation options applicable to this node -->
                    <connection-creation-options>
                       <property name="prop" value="val"/>     
                    </connection-creation-options>
                </node>
             </cluster>  
        </clusters>
    </client-context>
</jboss-ejb-client>

> While writing a documentation for server to server EJB invocations when security is involved, I just noticed that we lack a way to let the user deployments configure security and other connection details for dynamic nodes that participate in the clustered invocation. Consider the following scenario:
> 1) Server A and Server B both running in standalone HA mode. Both server A and B have a deployment "foo" containing clustered SFSBs.
> 2) Server C is a client server (may or may not have cluster capability). 
> 3) Server C has a deployment "bar" containing a jboss-ejb-client.xml with reference to a outbound remoting connection:
> {code:xml}
> <jboss-ejb-client xmlns="urn:jboss:ejb-client:1.0">
>     <client-context>
>         <ejb-receivers>
>             <remoting-ejb-receiver outbound-connection-ref="server-A-outbound-connection" />
>         </ejb-receivers>
>     </client-context>
> </jboss-ejb-client>
> {code}
> Server C has a outbound connection configuration to server A, configured in its remoting subsystem with appropriate security and other connection settings. 
> The "bar" application on server C invokes a SFSB from "foo" application on server A. Server A sends back the cluster topology to server C and that topology includes server B (and other nodes if any). Now server C has no knowledge on how to connect to server B with the appropriate security credentials. The EJB client API falls back on default connection options and will try to connect to server B, but that will obviously fail because those defaults won't be applicable in a secured server environment. 
> The infrastructure is in place, in EJB client API to dynamically connecting to the cluster nodes. What we are missing is a way to let users configure this. For a remote standalone client, we allow this via jboss-ejb-client.properties. We need something similar but more applicable for a client hosted on the server, in the jboss-ejb-client.xml.
