      Using exclude-local-receiver="true" would workaround this, as it would never try a local-receiver in the jboss-ejb-client.xml in the app:

      <jboss-ejb-client xmlns="urn:jboss:ejb-client:1.0">
   <client-context>
      <ejb-receivers exclude-local-receiver="true">
   </client-context>
</jboss-ejb-client>

      Client calling Clustered EJB fails with authentication issue when it uses the local-receiver

      Setup:

      • EJB deployed on 2 nodes which are clustered
      • EJB is protected with @SecurityDomain, @RolesAllowed
      • Client looks up the EJB via new InitialContext(host/port/user/pass) where the host is either node1 or node2
        • it holds this reference
        • invokes methods on it several times
        • since the ejb is clustered, it will load balance and hit node1 and node2

      Behavior:

      The EJB invocation will succeed twice, when it is using a remote-receiver such as remote+http://127.0.0.1:8080 :

       DEBUG [org.jboss.ejb.client.invocation] (default task-1) sendRequest: setting receiver, strong affinity = Cluster "ejb", weak affinity = None, remote destination is: remote+http://127.0.0.1:8080
 

      ...

      But then it will switch and try to use the local-receiver to invoke the EJB when it is in the same JVM as the client, when this happens it has no identity so it ends up in this error:

      DEBUG [org.jboss.ejb.client.invocation] (default task-1) sendRequest: setting receiver, strong affinity = Cluster "ejb", weak affinity = None, remote destination is: local:-

      Attaching debug logs

      • client-8080-logs.zip , this is when the client creates the InitialContext with localhost:8080 and client is on the same JVM localhost:8080
      • client-8180-logs.zip , this is when the client creates the InitialContext with localhost:8180 and client is on the same JVM localhost:8080

      Tests where client uses localhost:8180 in the initial contexts results in this when clicking invoke several times: server2, server1, fail with authorization exception

      When client uses localhost:8080, it results in : server1, server1, fail with authorization exception
