---------------------------------
Summary: Custom authentication plugin should not need to
prepopulate users in system_auth.users column family
Key: CASSANDRA-5651
URL: https://issues.apache.org/jira/browse/CASSANDRA-5651
Project: Cassandra
Issue Type: Improvement
Components: Core
Affects Versions: 1.2.5
Environment: RHEL 6.3, jdk 1.7
Reporter: Bao Le
Current implementation in ClientState.login makes a call to
Auth.isExistingUser(user.getName()) if the AuthenticatedUser is not Anonymous.
This involves querying system_auth.users column family.
Our custom authentication plugin does not need to pre-create and store users,
and it worked fine under 1.1.5. On 1.2.5, however, we run into authentication
problem because of this.
I feel we should either do this isExistingUser check inside
IAuthenticator.authenticate, or expose another boolean method similar to
IAuthenticator.requireAuthentication() so that custom authentication plugin can
skip this isExistingUser check if needed.
