Sam Tunnicliffe updated CASSANDRA-12813:
----------------------------------------
Fix Version/s: 2.2.x
Status: In Progress (was: Patch Available)
The patch LGTM, but it occurs to me that {{CassandraAuthorizer}} is just as
susceptible to this as {{PasswordAuthenticator}}. As it stands, the
probabililty of hitting the issue during authz is going to be minuscule because
most of the time we'd hit it during authn, but this patch could change that.
Would you mind extending the patch to cover {{CassandraAuthorizer}} too please
