Wildfly 10.1.0 getting "anonymous" as principal name in EJB - wildfly

Question

Problem Statement: context.getCallerPrincipal().getName() always gives "anonymous" with following client and server settings
I have done all the settings required. My security domain is using a Custom spring security module for JAAS login. The client acts as an installer for the application. The main application is deployed on wildfly 10.1 and installer launches as a standalone application which access the remote EJBs from the server. The EJB access is successfully but when I access caller principle from context it always gives "anonymous"
Client Side Settings:
jboss-ejb-client.properties:
remote.connections=default
remote.connection.default.port=8080
remote.connection.default.host=127.0.0.1
remote.connectionprovider.create.options.org.xnio.Options.SSL_ENABLED=false
remote.connection.default.connect.options.org.xnio.Options.SASL_POLICY_NOANONYMOUS=false
remote.connection.default.username=root
remote.connection.default.password=catch22*
Initial Context Creation:
Properties prop1 = new Properties();
prop1.put(Context.URL_PKG_PREFIXES, "org.jboss.ejb.client.naming");
prop1.put("org.jboss.ejb.client.scoped.context", "true");
System.out.println("setup() ################### 1");
context = new InitialContext(prop1);
Used jboss-client.jar
I have used the jboss-client.jar lib provided with in "WILDFLY_HOME/bin/client" directory
Server Side Settings
ejb realm:
Added following ejb realm in standalone-full.xml
<security-realm name="ejb-outbound-realm">
<server-identities>
<secret value="Q29ubmVjdGlvblBhc3N3b3JkMSE="/>
</server-identities>
</security-realm>
remoting subsystem settings:added out bound connection as follows
<outbound-connections>
<remote-outbound-connection name="ejb-outbound-connection" outbound-socket-binding-ref="ejb-outbound" security-realm="ejb-outbound-realm" username="root">
<properties>
<property name="SASL_POLICY_NOANONYMOUS" value="false"/>
<property name="SSL_ENABLED" value="false"/>
</properties>
</remote-outbound-connection>
</outbound-connections>
Against out bound connection I have added following socket binding group
<outbound-socket-binding name="ejb-outbound">
<remote-destination host="localhost" port="8080"/>
</outbound-socket-binding>

After above settings, when I am calling context.getCallerPrincipal().getName() it always gives me "anonymous"
Please help!
