[keycloak-dev] Cluster security

[Matthew Casperson]

The docs state that "By default there's nothing to prevent unauthorized
nodes from joining the cluster and sending potentially malicious messages
to the cluster." (
http://keycloak.github.io/docs/userguide/keycloak-server/html/clustering.html
)

Is this still the case if the jgroups stack in Wildfly has implemented the
AUTH protocol? For example, the Openshift Wildfly config looks something
like this:

    <stack name="tcp">
        <transport type="TCP" socket-binding="jgroups-tcp">
            <property name="external_addr">${env.OPENSHIFT_GEAR_DNS}</property>
            <property
name="external_port">${env.OPENSHIFT_WILDFLY_CLUSTER_PROXY_PORT}</property>
            <property
name="bind_port">${env.OPENSHIFT_WILDFLY_CLUSTER_PORT}</property>
            <property name="bind_addr">${env.OPENSHIFT_WILDFLY_IP}</property>
            <property name="defer_client_bind_addr">true</property>
        </transport>
        <protocol type="TCPPING">
            <property name="timeout">30000</property>
            <property
name="initial_hosts">${env.OPENSHIFT_WILDFLY_CLUSTER}</property>
            <property name="port_range">0</property>
            <property name="num_initial_members">1</property>
        </protocol>
        <protocol type="MERGE2"/>
        <protocol type="FD"/>
        <protocol type="VERIFY_SUSPECT"/>
        <protocol type="BARRIER"/>
        <protocol type="pbcast.NAKACK"/>
        <protocol type="UNICAST2"/>
        <protocol type="pbcast.STABLE"/>
        <protocol type="AUTH">
            <property name="auth_class">org.jgroups.auth.MD5Token</property>
            <property name="token_hash">SHA</property>
            <property name="auth_value">${env.OPENSHIFT_SECRET_TOKEN}</property>
        </protocol>
        <protocol type="pbcast.GMS"/>
        <protocol type="UFC"/>
        <protocol type="MFC"/>
        <protocol type="FRAG2"/>
        <!--protocol type="pbcast.STATE_TRANSFER"/>
        <protocol type="pbcast.FLUSH"/-->
    </stack>
