When connecting via native Java client 3.6.x, it needs to have a name/password pair that matches one listed on the cluster side.
<group>
<name>dev</name>
<password>dev-pass</password>
</group>
If there is no match, the client will fail with "com.hazelcast.client.AuthenticationException: Invalid credentials!".
When connecting via REST client it seems to work fine without any credentials at all.
I do not see any examples in the Hazelcast REST documentation making use of these credentials. I was expecting something like "curl -u dev:dev-pass ..."
Does this "authentication" feature exist for REST client? Is there any security associated with REST client?
Thank you for your response.
