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 & 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 116 Managing the PowerVault NX3500
