DSE Authentication

DSE 5.0 introduced a DSE Unified Authenticator. The DSE Authenticator can be used for internal Cassandra plaintext authentication by configuring the cluster to use a given username/password for authentication to the DSE cluster.

Background

Given

a running dse cluster with dse authentication enabled

And

the following example:

require 'dse'

begin
  cluster = Dse.cluster(
              username: ENV['USERNAME'],
              password: ENV['PASSWORD']
            )
  puts "authentication successful"
rescue Cassandra::Errors::AuthenticationError => e
  puts "#{e.class.name}: #{e.message}"
  puts "authentication failed"
else
  cluster.close
end

Authenticating with correct credentials

When

it is executed with a valid username and password in the environment

Then

its output should contain:

authentication successful
