Dell OpenManage™ Security 29
Table 2-4 defines the user privilege level abbreviations used in Table 2-3.
Authentication
The Server Administrator authentication scheme ensures that the correct access types are assigned to the
correct user privileges. Additionally, when you invoke the CLI, the Server Administrator authentication
scheme validates the context within which the current process is running. This authentication scheme
ensures that all Server Administrator functions, whether accessed through the Server Administrator
home page or CLI, are properly authenticated.
Microsoft Windows Authentication
For supported Windows operating systems, Server Administrator authentication uses Integrated
Windows Authentication (formerly called NTLM) to authenticate. This authentication system allows
Server Administrator security to be incorporated in an overall security scheme for your network.
Red Hat

Enterprise Linux and SUSE
®
Linux Enterprise Server Authentication
For supported Red Hat Enterprise Linux and SUSE Linux Enterprise Server operating systems, Server
Administrator authentication is based on the Pluggable Authentication Modules (PAM) library.
This documented library of functions allows an administrator to determine how individual applications
authenticate users.
Encryption
Server Administrator is accessed over a secure HTTPS connection using secure socket layer (SSL)
technology to ensure and protect the identity of the system being managed. Java Secure Socket
Extension (JSSE) is used by supported Windows, Red Hat Enterprise Linux, and SUSE Linux Enterprise
Server operating systems to protect the user credentials and other sensitive data that is transmitted over
the socket connection when a user accesses the Server Administrator home page.
Microsoft Active Directory
The Active Directory service software acts as the central authority for network security, letting the
operating system readily verify a user's identity and control that user’s access to network resources for
Dell OpenManage applications running on supported Windows platforms. Dell provides schema
extensions for customers to modify their Active Directory database to support remote management
authentication and authorization. IT Assistant, Server Administrator, and Dell remote access controllers
can now interface with Active Directory to add and control users and privileges from one central
database. For information about using Active Directory, see "Using Microsoft® Active Directory®."
