Dell PowerVault 770N (Deskside NAS Appliance) - Manual (Page 68)

If you are defining explicit maps, you create user and group maps individually. To create explicit maps, perform the following
steps:
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 to populate the UNIX users box.
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 NAS system. All maps are contained on this system.
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 for Windows 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 a 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 '^'
To set up the character translation, perform the following steps:
