default['wildfly-clu']['user']

    #group name
default['wildfly-clu']['group'] = "wildfly"

    #app name
default['wildfly-clu']['name']  = "wildfly"  ##/usr/local/SYMBOLIC_LINK  => /usr/local/wildfly-8.8.8-Final

    #Set true to deploy the HelloWorld.war
    default['wildfly-clu']['wildfly']['deploy_hello_world'] = true

#set this to true in order to configure an haproxy for the slaves declared in the cluster schema
default['wildfly-clu']['wildfly']['haproxy'] = true

#password for the slave realm.. use encrypted databag for increase security
default['wildfly-clu']['wildfly']['ManagementRealm'] = "a2VybmVscGFuaWMhMTIz"

    username:  admin
password:  admin    
    Default username for slave-master communication:
username:  slave
    password:  kernelpanic!123

    In order to configure different user with a different password:
 1. launch on the domain controller server add-user.sh
 2. create and user 
 3. Is this new user going to be used for one AS process to connect to another AS process? 
 e.g. for a slave host controller connecting to the master or for a Remoting connection for server to server EJB calls.
 yes/no? yes
 4. Replace mgmt-users.properties mgmt-groups.properties with new new ones in the template dir of this cookbook.
