Getting security or remoting Exceptions while deploying a clustered ejb application with an EJB outbound-connection in EAP6

Issue

• If an application is deployed to a cluster which is using a remote (outbound-connection) to another server why there is this error

ERROR [org.jboss.remoting.remote.connection] (Remoting "node2" read-1) JBREM000200: Remote connection failed: javax.net.ssl.SSLException: Unrecognized SSL message, plaintext connection?
INFO  [org.jboss.as.ejb3.remote.RemotingConnectionClusterNodeManager] (ejb-client-cluster-node-connection-creation-4-thread-2) Could not create a connection for cluster node node1 in cluster ejb: java.lang.RuntimeException: javax.net.ssl.SSLException: Unrecognized SSL message, plaintext connection?

• If an application is deployed to a cluster which is using a remote (outbound-connection) to another cluster why there is this error

JBREM000200: Remote connection failed: javax.security.sasl.SaslException: Authentication failed: all available authentication mechanisms failed 

• After modifying the cluster-passivation-store name within the configuration the out going ejb connections failed with an SSL message

ERROR [org.jboss.remoting.remote.connection] (Remoting "node2" read-1) JBREM000200: Remote connection failed: javax.net.ssl.SSLException: Unrecognized SSL message, plaintext connection?

• A standalone ejb client work without any error messages but if an application is used inside of a clustered server there are error messages in the logfile, what is the reason and how can the error avoided?
