Authentication Failed (WFHTTP000008) while calling EJB over HTTP using wildfly http naming client - wildfly

Question

We are trying to use wildfly-http-naming-client for http://host:8080/wildfly-services (instead of remote+http://host:8080/ ) and facing below mentioned exception. Have added the wildfly-config.xml to the java path using -Dwildfly.config.url= option.
Exception trace:
getInitialContextForSubsystem {java.naming.provider.url=http://somehost.ekiies.com:8180/wildfly-services, java.naming.factory.initial=org.wildfly.naming.client.WildFlyInitialContextFactory, java.naming.factory.url.pkgs=org.jboss.ejb.client.naming, jboss.naming.client.ejb.context=true}
