Summary: CEP-50: Authentication Negotiation
Key: CASSANDRA-20768
URL: https://issues.apache.org/jira/browse/CASSANDRA-20768
Project: Apache Cassandra
Issue Type: Epic
Components: Client/java-driver, Feature/Authorization
Reporter: Joel Shepherd
CEP-50 proposes a negotiation mechanism implemented using Cassandra's existing
native protocol that will enable clients to tell the node what authentication
mechanisms they support, and enabling the node to use its most preferred
authenticator that the client supports.

https://cwiki.apache.org/confluence/display/CASSANDRA/CEP-50%3A+Authentication+Negotiation
The goals of CEP-50 are:
* Enable clients to negotiate an authentication method with a node at time of
connection via the existing native protocol.
* Reduce the effort and risk of changing authentication method for a running
cluster.
* Enable operators to more easily enable environment-specific authentication
mechanisms.
* Provide seamless backwards-compatible interoperability for existing clients
and nodes that don't support authenticator negotiation.
Out-of-scope: {color:#000000}Other initiatives mentioned in CEP-31 —
user-specific negotiation, multiple role managers, authorization features,
negotiated inter-node authentication, specific authentication mechanisms — are
out of scope of this CEP. These additional initiatives are either extensions of
a basic authenticator negotiation solution, or touch on orthogonal concerns
like authorization and inter-node authentication.{color}
