Configuring system_auth and dse_security keyspace replication
The system_auth and dse_security keyspaces store security authentication and authorization information.
The system_auth and dse_security keyspaces store security authentication and
authorization information.
- DataStax Enterprise uses the system_auth keyspace when you enable any kind of authentication.
- DataStax Enterprise uses the dse_security keyspace on all nodes.
Attention: To prevent a potential problem logging into a secure cluster, set
the replication factor of the system_auth and dse_security keyspaces to a value that
is greater than 1. In a multi-node cluster, using the default of 1 prevents logging into any node when the node that stores the user data is down.
Use a keyspace command such as ALTER KEYSPACE to change the replication factor.
Setting the replication factor
Follow this procedure to increase the replication factor of the system_auth and dse_security keyspaces.
