130 Managing the PowerVault NX3500
Authentication
The Authentication entry allows you to configure the authentication
authorities, such as Network Information Services (NIS), Active Directory
(AD), and Light-weight Directory Access Protocol (LDAP). In addition, you
can manage local users and groups and map user names from Windows SIDs
to UNIX UIDs.
PowerVault NX3500 supports the following configuration modes:
• Active Directory Authentication Mixed Mode and Native Mode
• NIS authentication only
• LDAP authentication only
• Local internal users only
• NIS or LDAP and Active Directory

Configuring an Identity Management Database

An Identity Management Database allows the system to authenticate and
manage user-level access control. This database is responsible for managing
the users and their passwords, the groups, and the relationship between users
and groups.
If the system belongs to an Active Directory domain, then it also serves as an
identity management database. You can define additional UNIX databases
if needed.
UNIX identity management databases include NIS and LDAP, and they are
relevant only when clients access the system using the NFS protocol
(UNIX/Linux clients).
You can choose one of the following options, based on your network
environment:
• Enable user authentication through an NIS database
• Enable user authentication through an LDAP database
• Disable the use of an external UNIX identity management database
