The Oracle ILOM software that is pre-installed on the SP is preconfigured with two user accounts, root and default. The root user can create additional user accounts as needed. The default user is limited to password recovery of the root account and requires proof of physical presence at the server.
For a secure login method, enable an SSH service. Refer to the Oracle ILOM documentation for more information.
