Remote Invocation of EJB in WildFly 10 using JNDI lookup - wildfly

Question

Im trying to invoke an EJB from a remote server using JNDI lookup, Im using EJB3 with Spring-MVC in WildFly 10 and the configuration guided in this documentation has been done in my client and remote server
https://docs.jboss.org/author/display/WFLY10/EJB+invocations+from+a+remote+client+using+JNDI
But still I'm not able to get the connection of remote server.
1) Created a user under ApplicationRealm and gave the permissions for master slave setup for remote EJB Invocation.
2) This is my jboss-ejb-client.properties file, Here I have given the wildfly User_Name and Password of Host server.
endpoint.name=client-endpoint
remote.connections=one, two
remote.connection.one.host=172.16.25.26
remote.connection.one.port=8080
remote.connection.one.username=ABCD
remote.connection.one.password=ABCD#123
remote.connection.two.host=localhost
remote.connection.two.port=8080
remote.connection.two.username=guest
remote.connection.two.username=guest
# org.jboss.as.logging.per-deployment=true
My exception is
javax.naming.AuthenticationException: Failed to connect to any server. Servers tried:
[http-remoting://172.16.25.26:8080 (Authentication failed: all available authentication mechanisms failed:

Please tell me what am I missing here thats causing this exception and what is the significance of secret-key generated while creating the user in wildfly and where to configure that key
