User Name Mapping
User Name Mapping provides mapping of names between the UNIX and Windows environments. You can configure User
Name Mapping from the SFU MMC Console or by using the NAS Manager to configure properties for the NFS Sharing
Protocol. With User Name Mapping, you can create simple maps between Windows Powered user accounts and
corresponding UNIX accounts. You can also use the Advanced Map feature to map accounts with dissimilar names. Given
that UNIX user names are case-sensitive, while Windows Powered operating system names are not, the use of User Name
Mapping can greatly simplify maintaining and managing accounts in the two environments. User Name Mapping uses
Network Information Service (NIS) or local Personal Computer Network File System (PCNFS) user and group files to
authenticate users. Also, User Name Mapping supports bidirectional one-to-many mapping, allowing you to map a single
UNIX or Windows Powered operating system account to multiple accounts in the other environment. For example, you can
map more than one administrative account in a Windows Powered operating system to the UNIX root account.
To create user and group name maps, perform the following steps:
1. Log in to the NAS Manager.
See "
" in "NAS Manager."
2. From the NAS Manager, click Shares.
3. Click Sharing Protocols.
4. Click NFS Protocol, and then click Properties.
5. Click User and Group Mappings.
6. Use the User and Group Mappings window to define your user and group maps.
Configuration
To configure the type of server to be used to access UNIX user and group names, perform the following steps:
1. On the User and Group Mappings window, click General.
2. Click Use NIS server, or click Use password and group files to select the server type.
3. Depending on whether you use an NIS server or password and group files, perform one of the following steps:
For password and group files, specify the location and filename of the UNIX password file and UNIX group
file.
NOTE:
The UNIX password file and group file formats must conform to the UNIX standard for these files.
For NIS server, type the NIS domain and, optionally, the name of the NIS server.
4. Click OK to apply the configuration.
Defining Maps
To define simple maps in SFU, select the Simple Maps check box, and then perform the following steps:
1. In the User and Group Mappings window menu, click Simple Mappings.
2. Click Enable Simple Mapping.
3. Specify the Windows Domain.
4. Click OK to create the maps.
If you are defining explicit maps, you create user and group maps individually. To create explicit maps, perform the
following steps:
