Reset Authenticator Password

This procedure describes the steps that need to be done in a case a user lost his password and can not reset it with a super user. The procedure requires a cluster downtime and all the system_auth information will be removed.

Procedure

1. Stop Scylla nodes (Stop all the nodes in the cluster).
sudo systemctl stop scylla-server
2. Remove your tables under /var/lib/scylla/system_auth.
rm -rf /var/lib/scylla/system_auth
3. Start Scylla nodes.
sudo systemctl start scylla-server
4. Verify that you can log in to your node using cqlsh command.
The access is only possible using Scylla superuser.
cqlsh -u cassandra -p cassandra
5. Recreate the users
