Apply the following general guidelines when you manage user accounts:
ILOM supports a maximum of 10 user accounts, one of which is the preconfigured Administrator account. The preconfigured Administrator account cannot be deleted. If all 10 user accounts are configured, you must delete an existing user account before you can add a new user account.
Only accounts with Administrator privileges are allowed to add, modify, or delete user accounts. However, a user with Operator privileges can modify his or her own password.
The user name of an account must be at least four characters and no more than 16 characters. User names are case sensitive and must start with an alphabetical character. You can use alphabetical characters, numerals, hyphens, and underscores. Do not include spaces in user names.
You can either configure local accounts or you can have ILOM authenticate accounts against a remote user database, such as Active Directory, LDAP, or RADIUS. With remote authentication, you can use a centralized user database rather than configuring local accounts on each ILOM instance. In addition, remote authentication lets you change a user’s password on the server once.
