Password authentication works with dse 3.1 and higher and cql-rb 1.2.0 or better. Only dse 3.0 has the problem of not using the standard password authenticator. After 3.1 the default cassandra one is available.
I have tested this and have systems working in production using cql-rb 1.2.0 and dse 3.5.1 with password authentication turned on.
Documentation should be updated to reflect the state of support.
