Dell PowerVault 715N (Rackmount NAS Appliance) - Manual (Page 84)

1. On the User and Group Mappings window menu, click Explicit User Mapping to create user maps, or click
Explicit Group Mapping to create group maps.
2. Specify the Windows Domain. If the server is configured as PCNFS, go to step 4.
3. Click List UNIX Users or List UNIX Groups.
This action refreshes your UNIX users or groups selection.
4. Create map entries by selecting a Windows user or group and a UNIX user (UID) or group (GID) from the list and
clicking Add.
5. Click OK to create the maps.
Basic Scenarios
For UNIX and Windows NT User Name Mapping, an NIS Server must already exist in the UNIX environment or UNIX user
and group files must exist on the PowerVault NAS system. User Name Mapping associates UNIX users and groups to
Windows NT users and groups. You can use two types of maps, simple and explicit. Simple maps define a one-to-one
relationship between the same user names and groups. Explicit maps define a relationship between dissimilar user names
and groups.
Workgroup
In the workgroup scenario, you configure User Name Mapping locally on the PowerVault 715N system. All maps are
contained on this system.
Domain
In the domain scenario, you configure NFS Authentication on all domain controllers. The NT Authentication Service
installation program must be installed on the domain controller and available in the DomainUtils share on the NAS
system.
To install the NT Authentication Service on a domain controller, perform the following steps:
1. Log in to the domain controller as an administrator.
2. Map the NAS system's DomainUtils share.
3. Run sfucustom.msi, which is located in the Services for Unix directory.
Filename Character Translation
Although Windows and UNIX file systems do not allow certain characters in filenames, the characters that are prohibited
by each operating system are not the same. For example, a valid Windows filename can not contain a colon (:), but a
UNIX filename can. If a UNIX user attempts to create a file in an NFS share and that file contains an illegal character in its
name, the attempt will fail.
You can use filename character translation to replace characters that are not allowed in a file system by mapping them to
characters that are valid. To enable filename character translation, create a text file that maps Windows to UNIX
characters, and then modify the registry entry that specifies the path and name of the translation file.
The filename character translation text file is a list of mapped characters in the following format, such as the following:
0xnn : 0xnn [ ; comment ]
where nn is the hexadecimal value of the character
The entry for a map from the UNIX character ":" to the Windows character "-" in the filename character translation text is
as follows:
0x3a : 0x2d ; Map ':' (0x3a) to '-' (0x2d)
To map the character combination "()" to the character "^", add the following entry:
0x28 0x29 : 0x5e ; Map '()' to '^'
