HP ProLiant SB460c SAN Gateway Storage Server - Manual (Page 71)

You can back up and restore User Name Mapping data at any time. Because the database is backed
up to a file, you can use that file to copy the mapping database to another server. This provides
redundancy for the sake of fault tolerance.
NOTE:
If you obtain information from multiple NIS domains, it is assumed that each domain has unique users and
user identifiers (UIDs). User Name Mapping does not perform any checks.
User Name Mapping associates Windows and UNIX user names for Client for NFS and Server for
NFS. This allows users to connect to Network File System (NFS) resources without having to log on
to UNIX and Windows systems separately.
NOTE:
Most of the functionality of User Name Mapping has been replaced by Active Directory Lookup. Active
Directory Lookup enables Client for NFS and Server for NFS to obtain user identifier (UID) and group
identifier (GID) information directly from Active Directory. For information about storing UNIX user data
in Active Directory, see documentation for Identity Management for UNIX. For information about enabling
Active Directory Lookup, see “Specifying how Server for NFS obtains Windows user and group information”
available in the online help.
User Name Mapping Administration
The User Name Mapping administration online help contains information for the following topics:
• Understanding the User Name Mapping component
• Starting and stopping User Name Mapping
• Configuring User Name Mapping
• Securing access to the User Name Mapping server
• Managing maps
• Managing groups
Best practices for User Name Mapping
• Install User Name Mapping on a domain controller.
• Create a User Name Mapping server pool.
• Configure User Name Mapping on a server cluster.
• Make sure User Name Mapping can download users from all domains.
• Refresh data whenever a user is added or changed.
• Place password and group files on the User Name Mapping server.
• Use appropriate permissions to protect password and group files.
• Ensure consistency of group mapping.
• Specify the computers that can access User Name Mapping.
