You c an back up and restore User Name Mapping data at any time. Because the database is backed up
to a file, you c a n 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 multi ple 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 o n 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Most of the functionality of User Name Mapping has been replaced by Active Directory Lookup.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 N FS obtains Windows user and group
information” available in online help.

Test an NFS file share configuration
The following steps provide the tasks necessary verify the set up of NFS shares, user mappings, and
permissions granting the desired access to an NFS share on the storage server.
1. Create an NFS share.
