How can I reset the admin password in Datastax Opscenter? Will disabling and reenabling authentication in /etc/opscenter/opscenterd.conf do the trick? Will I lose any other data in the process?
Turns out this was fairly simple. All I needed to do was stop OpsCenter, rename (or remove) passwd.db, and restart OpsCenter again. The daemon automatically creates a new password db file and sets the admin password to 'admin'.
