GEODE-420: Reverting checkAttributes change in AbstractDistributionConfig.java.
> locator ssl configuration
> -------------------------

> Key: GEODE-420
> URL: https://issues.apache.org/jira/browse/GEODE-420
> Project: Geode
> Issue Type: New Feature
> Components: locator
> Reporter: Darrel Schneider
> Assignee: Udo Kohlmeyer
>
> We currently allow separate SSL configuration for cluster, server, gateway,
> jmx-manager, and http-service.
> The "server" attributes configure the ssl connections from clients to a cache
> server.
> The "gateway" attributes configure the ssl connections between a gateway
> sender and receiver.
> The "jmx-manager" attributes configure the ssl connections between an admin
> client (for example gfsh) and the jmx-manager.
> The "http-service" attributes configure the ssl connections between REST
> clients and the http-service.
> The "cluster" attributes configure the ssl connections between the members of
> a distributed system (peer-to-peer connections) AND to the locators.
> Using "cluster" for the connections to a locator can be a problem.
> Say you trust all your members of a distributed system since they are running
> on your private network. So no need for ssl on the p2p connections.
> So you disable cluster-ssl. These means that your peers are locators are all
> using unsecure connections.
> But some of these members are hosting a cache server and have clients
> connecting to them. So you configure "server" ssl for the client to server
> connections. But for your clients to find you servers they need to talk to
> the locator. Since the clients are coming from the outside world you want
> them to use SSL. So you configure "server" ssl on them for when they connect
> to the cache server and "cluster" SSL on them for when they connect to the
> locator. But your locators are configured with "cluster" SSL disabled so that
> the p2p connects on the internal network will not be SSL.
> So you are either forced to have you client to locator connections to be
> unsecure or you need to secure all the cluster connections forcing the peers
> to also use SSL.
> I think we should introduce "locator" SSL configuration options that would
> allow you to have just the locator and server using SSL and the "cluster" to
> have SSL disabled.
> Something else to consider would be for the locator to be able to use SSL for
> clients but non-SSL for locator-to-locator and peers-to-locator connections.
> I think this would be more complicated because we would need to have
> different ports that the locator listens on (one for clients and one for
> locators and members).
