> The system_auth keyspace uses a QUORUM consistency level when checking authentication
for the default cassandra user. For all other users created, superuser or otherwise, a LOCAL_ONE
consistency level is used for authenticating.

> But for my new superuser, new node members are rejected because QUORUM CL can't be achieved:
