Oracle ILOM supports Active Directory, the distributed directory service included with Microsoft Windows Server operating systems. Like an LDAP directory service implementation, Active Directory can be used to authenticate user credentials of users logging into Oracle ILOM.
You can also optionally create groups that are assigned roles and contain users who are granted privileges based on those roles of the group.
